1.GENERAL INFORMATION

1.1 Automatic Brinell Test Methods

The Automat�c Br�nell System makes a Br�nell �mpress�on �n conformance w�th the standard method for Br�nell test�ng as descr�bed �n ASTM E10. The �mpress�on made by the Automat�c Br�nell may be measured opt�cally by an operator to atta�n the Br�nell Hardness Number. The Automat�c Br�nell tester, however, �nstead of measur�ng the w�dth of the �mpress�on w�th a scope, automat�cally measures the depth of the �ndentat�on. (The depth measurement method �s descr�bed �n ASTM E103.) Th�s techn�que prov�des the advantages of greater speed and reduced operator �nfluence on the test results. S�nce no opt�cal measurements are made, d�fferent operators w�ll cons�stently prov�de except�onally repeatable test results.

L�ke the Rockwell hardness test method, th�s depth measurement �s calculated based on the d�fference �n penetrat�on depth between a preload and a major load pos�t�on. The tester appl�es a preload, zeros the measurement, appl�es the full load, returns to the preload sett�ng and makes �ts depth read�ng. The zero�ng funct�on �s automat�cally done both mechan�cally and electron�cally.

For a g�ven mater�al th�s depth measurement has been establ�shed to be l�nearly related to the w�dth measurement, but th�s relat�onsh�p may change from one mater�al to another. Some examples of spec�fic factors that can offset th�s relat�onsh�p are the elast�c recovery of the mater�al that causes the bottom of the �mpress�on to compress to d�fferent depths. Also, the r�dge of mater�al that forms around the l�p of the �mpress�on may be h�gher for some mater�als.

In order to compensate for these factors, the Automat�c Br�nell can be programmed to adjust the readout so �t accurately reflects the actual l�near relat�onsh�p between the depth and the w�dth of the �mpress�on. Th�s relat�onsh�p �s eas�ly establ�shed by mak�ng tests and compar�ng the automat�c readouts w�th opt�cal measurements of the same �mpress�ons. Then the tester �s told to offset �ts own calculat�on of the results by a certa�n value so that �t w�ll thereafter read accurately on that mater�al. Once the mach�ne has been set up for a mater�al, �t can eas�ly be changed to a d�fferent offset for another mater�al or changed back aga�n �n a few seconds. The tester can then be ver�fied for accuracy at any t�me by mak�ng an opt�cal read�ng of the d�ameter of the �mpress�on.

1.2 Machine Description

1.2.1 Basic Configuration

The tester cons�sts of a number of components as shown �n the �llustrat�ons �n the Spec�ficat�ons Sect�on. Insofar as poss�ble each component �s modular and des�gned for easy ma�ntenance or serv�c�ng. Pr�nc�pal components such as the test head and electron�c readout box, as well as sub‑ assembl�es, are eas�ly removed or replaced �n m�nutes w�thout any requ�rements for spec�al tools or sk�lls. The hydraul�cs are s�mple �n des�gn and standard �n manufacture so that they can be serv�ced by average shop ma�ntenance personnel. All electr�cal components have connectors on at least one s�de so they can be qu�ckly d�s‑connected, and external w�r�ng cables are keyed so that they can only be hooked up properly.

Page 1‑2

1.2.2 Test Head

The ma�n gaug�ng components of the Automat�c Br�nell are located �n the test head. The head �ncorporates load controll�ng elements, a measur�ng system, and other dev�ces to ensure safe operat�on and constant test parameters. The load controll�ng element �ns�de the head cons�sts of a h�gh accuracy load cell that accurately detects the load be�ng appl�ed. All load and measurement sett�ngs are eas�ly adjusted. (Refer to the ma�ntenance sect�on.) The depth sens�ng element �s an LVDT.

Other sens�ng dev�ces have been �ncorporated �nto the test head to detect certa�n cond�t�ons: soft mater�als (e.g. operators’ hands), unstable or non‑level test surfaces, or the absence of a test spec�men. When tr�ggered these dev�ces �n�t�ate an automat�c return of the test head. Also, some cond�t�ons of �mproper start pos�t�on�ng can be detected. In th�s case, the tester may prevent �tself from mak�ng a test, �f the part �s too far out of level.

The Automat�c Br�nell System uses a spec�al test surface reference dev�ce ‑‑ a float�ng nosep�ece or shroud that surrounds the �ndenter and wh�ch references the surface of the spec�men. Th�s feature allows the tester to reta�n accurate read�ngs even as the tester frame or test sample deforms dur�ng load, because �t ma�nta�ns contact to and reference w�th the or�g�nal preload pos�t�on dur�ng the test cycle. Another advantage to the nosep�ece �s that �t t�lts to allow test�ng on surfaces that are out of level by up to two degrees. Th�s means that cast�ngs w�th a normal draft angle may be tested w�th accurate results. Also, normal d�mens�onal var�at�on on the parts w�ll not adversely affect the results. Standard un�versal or custom�zed fixtur�ng may be requ�red, however to prov�de good lateral or rotat�onal stab�l�ty on some parts that fall outs�de the parameters for stable and accurate test spec�mens. (Please refer to the F�xtur�ng Sect�on.)

Page 1‑3

1.2.3 Electronic System

All the electron�cs are run off a 120V l�ne separate from the power supply to the hydraul�cs. Th�s l�ne should be �solated so that �rregular�t�es �n supply do not affect the electron�cs.

1.2.4 Test Stand

The stand has a C frame that carr�es the hydraul�c cyl�nder wh�ch appl�es the load.

1.2.5 Hydraulic Power Supply and Cylinder

The Automat�c Br�nell System has a hydraul�c system to dr�ve the test head through a 4" stroke. The power of the cyl�nder �s translated �nto a load.

2. OPERATION

(Please refer to the �llustrat�on �n the spec�ficat�on sect�on for actual part locat�ons)

2.1 Example of Standard Test Operation

1) Turn on power to hydraul�cs. Turn the OFF/ON sw�tch to the ON pos�t�on (at back of electron�c box). The d�g�tal readout w�ll say:

SELF TEST V XX.X

Th�s d�splay w�ll rema�n on for a short t�me wh�le perform�ng rout�ne checks of �nternal funct�ons and the transducer. After all funct�ons have been ver�fied for proper operat�on the tester w�ll enter the test mode and the d�splay w�ll show a ready status:

HB‑1 READY

Th�s d�splay would �nd�cate that the tester was �n the HB1 scale and the tester was ready to start perform�ng tests. The scale w�ll be set on the last scale selected even �f the un�t was turned off s�nce that select�on.

2) Properly pos�t�on a test spec�men on the anv�l and adjust the elevat�ng screw so the top surface of the spec�men �s w�th�n reach of the stroke of the test head and �s perpend�cular to the test surface.

(IMPORTANT: Please refer to the sect�on for F�xtur�ng to �nsure that the test spec�men �s �n a stable pos�t�on for test�ng.)

3) Depress the foot pedal (or �n�t�ate start sw�tch) and keep �t depressed for at least 0.5 seconds. The test head w�ll beg�n to move downward. If the foot pedal �s released at any t�me before full load �s reached, the tester w�ll stop and rema�n at the same pos�t�on unt�l the pedal �s act�vated aga�n and full load �s reached. (Th�s allows the operator to "jog" the test head down close to the test sample pr�or to test�ng to allow for opt�mum test pos�t�on�ng.)

(NOTE: The transducer detects the d�fference �n depth of penetrat�on between the �ndenter nosep�ece wh�ch �s pressed aga�nst the test surface and the �ndenter wh�ch has made an �ndentat�on �nto the surface. Th�s g�ves the depth measurement wh�ch �s then translated �nto a Br�nell Hardness Number or equ�valent d�ameter measurement by the programm�ng �n the console.)

After reach�ng the full load �s reached, the test head rema�ns �n th�s pos�t�on w�th the full load for the selected t�me‑at‑load, then automat�cally retracts. At th�s t�me the hardness value �s d�splayed. Typ�cally the d�splay would appear l�ke th�s:

HB‑1 208

Page 12: Automatic Brinell - hardnesstesters.com · Automatic Brinell Direct Reading Brinell Hardness Testing System ... L ke the Rockwell hardness test method, th s depth measurement s calculated

Page 2‑2

Th�s d�splay would �nd�cate that the tester was set �n the first Br�nell scale setup file and the Br�nell Hardness Number was 208.

The d�splay may show a tolerance �nd�cator, (OK, LO, HI). Each scale setup file can have �ts own tolerance sett�ngs. Refer to TOL (tolerance) key funct�ons.

When the test head returns to the “home” pos�t�on w�th the hydraul�cs retracted, the mach�ne �s ready for another test. Each succeed�ng test �s performed s�mply by plac�ng the part �n pos�t�on, depress�ng the foot pedal unt�l the d�al �nd�cates that full load has beers appl�ed, and read�ng out the hardness result from the d�g�tal d�splay.

PLEASE NOTE: In order to test the tester must �nd�cate a ready status by e�ther the “READY” readout on the d�splay or a test result from the preced�ng test.

2.2 Test Head Retraction

If at any t�me dur�ng the cycle, the Emergency Return button (customer suppl�ed) �s pressed or the tester senses a bad test parameter such as a soft mater�al (l�ke the operator’s hand) the test head �mmed�ately retracts to the home pos�t�on.

(CAUTION Regard�ng the safety sw�tch to retract the test head: �f the operator has h�s hand under the �ndenter dur�ng the load, the safety sw�tch w�ll not prevent �njury. It may lessen the degree of �njury.

2.3 Fixturing

F�xtur�ng plays an �mportant part �n stable accurate automat�c Br�nell test�ng. D�fferent funct�ons that fixtur�ng performs are:

2.3.1 Positioning

In a h�gh product�on test�ng env�ronment, �t �s often �mportant to automat�cally �ndex the proper test pos�t�on w�th a fixture so the operator does not have to take the t�me or use judgement to al�gn each part. If test�ng the the edge of a spec�men, pos�t�on�ng changes can dramat�call affect the hardness read�ng �f the test �s too close to the edge.

2.3.2 Orientation

The Automat�c Br�nell nodep�ece �s des�gned to t�lt sl�ghtly to enable accurate test�ng on sl�ghtly t�lted test surfaces.

If a part has a draft angle of MORE than two degrees, or has �rregular�t�es l�ke a part�ng l�ne and flash on the unders�de of the test spec�men that causes the part to t�lt more than two degrees, or has a shape that won’t support the spec�men, �t must be supported to or�ent the top surface so that �t �s close to perpend�cular to the ax�s of �ndentat�on.

Page 2‑3

2.3.3 Specimen Stability

Some part configurat�ons present an �nherently unstable shape for support�ng a load. Some common examples are shapes w�th curves �n more than one d�rect�on l�ke a football shape or a nose cone. Other parts that are �nherently unstable are long, narrow parts to be tested on the end. Small amounts of angle on the support�ng end can cause the spec�men to lean over at a substant�al angle wh�le the load �s appl�ed. These types of parts should be supported or referenced at the s�des so they w�ll not be able to lean.

2.3.4 Accuracy

Somet�mes �rregular�t�es such as large flashl�nes can cause a spec�men to rock sl�ghtly as �t settles �n under load. Th�s change �n or�entat�on changes the �ndenter to shroud relat�onsh�p after the preload has been zeroed. Th�s can cause �naccurate calculat�on of the depth of penetrat�on by the tester even though the final �ndentat�on g�ves an accurate result.

2.3.5 Compressible Test Samples

Some parts, such as cyl�ndr�cal shapes s�m�lar to a prov�ng r�ng, can compress under the load and, �n effect, store the force of the test load. If the part should break or sl�p under load, the large loadof the test can cause forceful eject�on of p�eces or the ent�re part present�ng a dangerous s�tuat�on to the ooperator.

CAuTION

1) Do not attempt to test parts that w�ll move under load. Injury may occur.2) Tra�n operators to detect parts that cannot be tested.3) Ver�fy proper funct�on�ng of all emergency sw�tches on a regular bas�s.

The follow�ng rout�ne w�ll enable any of the funct�on keys des�red:

1. Press�ng the CONV. key wh�le the mach�ne d�splays “READY” or �s first turned on causes the follow�ng message to appear on the d�splay:

SELF TEST V X.X

2. W�th�n a five seconds after th�s d�splay appears the operator must beg�n to �nput the secur�ty code number. If the operator fa�ls to beg�n to enter the secur�ty code procedure w�th‑�n the t�me allotted, the system w�ll revert back to the test mode. (Once the first key �s pressed the operator w�ll have about 60 seconds more to complete the procedure.) As each code number �s entered, the letters �n the d�aplay d�sappear from the left as confirmat�on.

2.4.3 Scale Selection Function

Th�s tester performs all �ts test�ng �n the HB30 scale (Br�nell Hardness w�th a 10mm carb�de ball and 3000 kg. load or opt�onally another load) . However, depend�ng on the system, th�s same scale may be stored �n the electron�c memory ‑ typ�cally 1‑ 3 t�mes. Each scale has a d�fferent scale number �n order to store d�fferent test parameters ‑ l�ke tolerances sett�ngs.

There �s no d�fference between any of these scale/files. They are all set up �n�t�ally the same way so the operator can ta�lor each of them to h�s needs. Each of the scales �s set up by default w�th only the bas�c �nformat�on necessary to get a Br�nell result. Th�s allows each of the scales to be set up, �f des�red, w�th other test parameters l�ke h�gh and low tolerances or a zero d�splacement (cal�brat�on) value. Once these parameters have been set up, the operator can qu�ckly sw�tch scales to test var�ous mater�als or parts w�thout enter�ng new parameters.

A few thousand test results may be stored �n a scale/file before �t becomes full. If an E‑17 or Memory Full, message appears the “Clear All” under the STAT key funct�ons should be used.

IMPORTANT: When the operator changes scales, all the test results stored �n the system memory for the last scale used w�ll be forgetten, unless the Spl�t Memory Opt�on �s �n use.

The hardness scale �s always d�splayed wh�le the tester �s �n the test mode. Typ�cal d�splays when the tester �s ready to perform a test m�ght be:

HB1 READY or HB1‑1 218

These d�splays would �nd�cate “READY” to start test�ng �n the first Br�nell scale or that �t had performed a test w�th a Br�nell value of HB 218, and was ready to perform another test.

OPERATION WITH SECuRITY CODE ACCESS:

Press�ng the SCALE SELECT key (when enabledw�th the secur�ty code), w�ll make the d�splay read:

HB‑1 1 YES?

Press�ng YES w�ll enter (select) the HB‑1 scale and return the tester to the test mode.

Press�ng NO w�ll stop the scale select�on funct�on and return the tester to the test mode �n the last scale that was actually entered.

Press�ng the SCALE SELECT key aga�n w�ll cause the readout to d�splay the next scale �n sequence. If the operator cont�nues to hold the SCALE SELECT key down, the tester w�ll cont�nue to d�splay each scale �n sequence at one second �ntervals. The operator may also press the SCALE SELECT key repeatedly to v�ew the scales �n sequence. At any po�nt a scale may be selected by press�ng the YES key. The operator may also choose to sk�p chang�ng scales by press�ng the NO key.

OPERATION WITHOuT SECuRITY CODE ACCESS:

The scale may not be changed w�thout secur�ty code clearance

2.4.4 Calibration (Cal) Key Function

The Cal�brat�on key �s normally used to control factory set software funct�ons and �s not normally access�ble. There are 3 parameters �nvolved �n the cal�brat�on wh�ch are �mportant to control:

1) Electron�c Cal�brat�on for d�fferent mater�als (refer to 0‑Set Key Funct�on).

2) Transducer Cal�brat�on (refer to Transducer Sect�on)

3) Load Cal�brat�on (refer to Load Cal�brat�on Sect�on)

Page 19: Automatic Brinell - hardnesstesters.com · Automatic Brinell Direct Reading Brinell Hardness Testing System ... L ke the Rockwell hardness test method, th s depth measurement s calculated

Page 2‑9

2.4.5 0-Set Key Function

The Zero D�splacement funct�on �s des�gned for prec�se cal�brat�on on a part�cular mater�al or for parts of the same mater�al but w�th a s�gn�ficant d�fference of hardness (normally 40 pts). Th�s funct�on should be used when test�ng on any long test nuns or other appl�cat�ons where accuracy �s most �mportant. Once the number �s set, �t should be good for that part whenever �t �s run. (If there �s a large range of hardness between d�fferent parts of the same mater�al, a s�ngle zero d�splacement value may not work for all the parts.)

W�th the mach�ne at or�g�nal cal�brat�on (no “*” on d�splay), the factory‑set zero d�splacement value �s 860. (DPTH = 100.0).

1. Number and test 5‑10 parts and record the Br�nell numbers test results from the tester.

2. Opt�cally read the �mpress�ons and record the Br�nell values next to the correspond�ng Automat�c Br�nell values. Make the read�ngs as accurate as poss�ble.

3. Average the 10 values from each ser�es of read�ngs (opt�cal scope and automat�c Br�nell) and calculate the d�fference,

4. If the automat�c values have an average value lower than the average opt�cal read�ngs, add the d�fference to the zero d�splacement value and enter that number �nto zero d�splacement. If �t’s h�gher, subtract from the zero d�splacement. Press 0 SET key, key �s the new number, press ENTER key, enter secur�ty code (see cal�brat�on cert�ficate).

5. Also note the range of values for each ser�es of read�ngs. They should be close to the same range. After the zero d�splacement �s adjusted the LED d�splay w�ll show a “*” at the r�ght s�de �nd�cat�ng that the mach�ne has been cal�brated.

Th�s procedure reduces the �nherent var�at�on �n opt�cal measurements of the w�dth of the �mpress�on. Subsequent read�ngs from the tester should match the opt�cal read�ngs, w�th�n approx�mately +/‑ 0.05mm.

Technical Note:

The Br�nell Hardness Scale may be graphed as a curve relat�ng w�dth of an �ndenter �mpress�on to the hardness of test mater�als. The depth‑of‑�ndentat�on curve �s l�nearly related to the d�ameter‑of‑�ndentat�on curve, but �n pract�ce th�s curve may have to be adjusted to account for the �nd�v�dual character�st�cs of a spec�fic mater�al. Examples of factors that can cause an offset are an�sotrop�c elast�c propert�es or plast�c deformat�on caus�ng d�ffer�ng r�dge effects around the l�p of the �mpress�on or d�ffer�ng amounts of elast�c recovery at the bottom of an �mpress�on. The cal�brat�on funct�on allows the curve that �s preset �n the computer memory to be adapted for d�fferent mater�als so that the automat�c depth measurement curve w�ll equate closely w�th the opt�cal w�dth measurement curve.

2.4.6 Tolerance (TOL) Function

The Tolerance funct�on allows the operator to v�ew or set h�gh and low tolerance l�m�ts �n only one of the HB scales for acceptable hardness results.

Each scale on file can have �ts own tolerance sett�ng. When tolerances are setup, hardness values w�ll be d�splayed w�th “HI”, “LO”. or “OK’’ �nd�cators. Ind�cators on the d�splay flash on and off.

OPERATION WITHOuT SECuRITY CODE ACCESS

Press�ng the TOL key, when the Tolerance funct�on A‑Mt enabled, w�ll cause the d�splay to show the h�gh and low tolerances. For example:

HB1 180, 220

Th�s d�splay would �nd�cate a h�gh tolerance l�m�t of 220 and a low tolerance of 180 for the HB‑1 scale. Th�s message w�ll rema�n on the d�splay unt�l e�ther the NO key �s pressed or unt�l another funct�on �s selected.

OPERATION WITH SECuRITY CODE ACCESS

1) If the “Br�nell Result” mode funct�on �s selected, press�ng the TOL key, when the Tolerance funct�on w�ll cause the d�splay to show the scale and the low tolerance sett�ng. For example:

HB1 LOW = 18O

(Press�ng NO or another funct�on button after press�ng the TOL key w�ll cause the system to return to the test mode w�thout chang�ng the low sett�ng.)

2) Press�ng numer�c keys and the ENTER key w�ll cause a new low tolerance value to replace the old one and the d�splay to show the current h�gh tolerance value (see next example). (Press�ng the ENTER key alone w�thout chang�ng the low tolerance value w�ll also cause the tester to d�splay the h�gh tolerance value.)

HB1 HIGH = 220

Th�s value may or may not be changed �n the same manner as the low tolerance value. When the ENTER key �s pressed the system w�ll return to the test mode.

To el�m�nate the Tolerance funct�on d�splay, set the h�gh and low tolerance values at “0” and “999”. No �nd�cat�on of HI, LO, or OK w�ll appear.

PLEASE NOTE: If the tolerances are changed �n the m�ddle of a lot, the pr�ntout and stat�st�cal calculat�ons w�ll use the final tolerance values for the ent�re lot.

2.4.7 Statistics (STAT) Functions

The STAT key funct�ons control the test �nformat�on stored �n the system memory.

There are five (or opt�onally 6) STAT funct�ons: Clear Last, Clear All, Sequence Number, Lot Number and Stat�st�cs (opt�onally Spl�t Memory). These funct�ons appear �n sequence when the operator presses the NO key as each appears on the d�splay unless the key does not have secur�ty code access

OPERATION WITH SECuRITY CODE ACCESS

CLEAR LAST

Press�ng the HISTORY DATA key w�ll cause the d�splay to read:

HB1 CLEAR LAST?

>>>) Press�ng YES w�ll remove the last hardness read�ng from the h�story data and the system w�ll return to the test mode. Th�s procedure can be repeated to remove add�t�onal read�ngs. If results are be�ng pr�nted, the last sequence # from the cleared test w�ll be repeated.

CLEAR ALL

Press�ng YES w�ll clear all the hardness results from the memory for a part�cular scale/file and return the system to the test mode.

PLEASE NOTE: The Clear All funct�on �s automat�cally performed each t�me the cal�brate funct�on �s performed or the zero d�splacement number �s changed.

SEQUENCE NUMBER

Press�ng YES w�ll select the SEQUENCE NUMBER funct�on. The sequence numbers are used to �dent�fy �nd�v�dual tests. Each t�me a test �s performed the sequence number �s �ncreased by a value of one to a max�mum of 65535. The sequence number w�ll appear on the test results pr�ntout. When the Sequence Number funct�on �s selected by press�ng YES the d�splay m�ght read:

HB1 SEQ# = 1332

(The “#” symbol as �t actually appears on the d�splay �n three parallel l�nes, Ξ.) Th�s d�splay shows the current scale �s HB‑1 and the last sequence number �s 1332. �f the HISTORY DATA key �s enabled and the test result memory �s cleared (through the Clear‑All funct�on), the operator may select and enter a new sequence number. To start a sequence at a g�ven number, he enters the pr�or sequence number. For example, to start the sequence at “I” the operator must enter “0”.

If the NO button or another funct�on button �s pressed before a new number �s entered, the system w�ll return to the test mode or �n�t�ate the new funct�on w�thout chang�ng the sequence number. After a number �s selected and entered the system w�ll return to the test mode.

LOT NUMBER

Press�ng YES w�ll select the LOT NUMBER funct�on. The Lot Number funct�on �s used to �dent�fy tests performed on part�cular groups of mater�als and w�ll appear on the pr�ntout. The lot number funct�on allows the operator to change the lot number. When th�s funct�on �s selected the d�splay m�ght read:

HB‑1 LOT 5858

Th�s d�splay would �nd�cate the system �s �n the HB1 scale and that the lot number �s 5858. The operator may now select and enter a new number �f the h�story data funct�on �s enabled. When YES �s pressed the d�splay w�ll clear to make room for a 16 d�g�t entry. The system w�ll return to the test mode. If the NO button �s pressed the system w�ll return to the test mode w�thout chang�ng the lot number.

STATISTICS

Press�ng YES w�ll enable the operator to v�ew the stat�st�cs. Th�s funct�on d�splays the mean and standard dev�at�on of the read�ngs. All the read�ngs s�nce the last Scale Select, Clear All, Cal�brat�on, or Zero D�splacement funct�on were performed w�ll be �ncluded �n these calculat�ons. A max�mum of 3500 values can be stored for stat�st�cal analys�s. The stat�st�cs d�splay m�ght read:

HB‑1 207.2, 2.443

The first number would �nd�cate an average value of 207.2 and the second number would �nd�cate a standard dev�at�on of 2.433. The calculat�on of the dev�at�on �s based on the Br�nell Hardness Numbers, not the d�ameter measurement. These values w�ll rema�n on d�splay unt�l the NO button or another funct�on button �s pressed.

SPLIT MEMORY (OPTIONAL)

Th�s feature allows the ava�lable memory to be d�v�ded �nto 30 separate files to allow �ndependent data analys�s of each file. For �nstance, mult�ple Br�nell files could be used and named HB1, HB2, etc. Each file w�ll have �ts own tolerances, h�story, etc. The file name �s user defined w�th up to 5 characters. The percentage of memory per file can also be set.

Press the ‘STAT” key and then the ‘NO” key unt�l the d�splay shows ‘SPLIT MEMORY?” Press�ng the “YES’ key w�ll cause the d�splay to read “ENTER CODE”. At th�s po�nt enter the code for Spl�t Memory. Th�s w�ll clear the h�story files to allow for reass�gnment of memory.

‑The d�splay w�ll now read “HB1” If you w�sh to change the head�ng, press the Scale Select button to beg�n character select�on sequence (see sect�on on alpha/numer�c characters �n these append�ces for deta�ls). If you w�sh to use the current head�ng, press ENTER to proceed.

2.4.8 Print Functions

There are ten Pr�nt funct�ons that may be used �n conjunct�on w�th a pr�nter:‑ Totals‑ Graph‑ H�story‑ X‑Bar & R Chart‑ Results/Values Only

These funct�ons appear �n sequence (w�th the poss�ble except�on of the Trace funct�on and the Set Baud Rate) when the operator presses the NO key repeatedly. Samples of the pr�ntouts are �ncluded at the end of the sect�on.

At Power Up the tester defaults automat�cally to Result mode wh�ch pr�ntout test values as performed. The Result mode slows down the tester operat�on sl�ghtly because the data �s be�ng transm�tted to pr�nter. To speed up operat�on w�thout pr�nter, remove Results funct�on..

OPERATION WITH SECuRITY CODE_ACCESS:

Note on Total and Graph Funct�ons

These funct�ons need tolerances to funct�on properly. The operator may add or change tolerances at any t�me before they are cleared and repr�nt Totals and Graph. (See sample pr�ntout at the end of th�s sect�on)

TOTALS (see sample printout at the end of this section)

Press�ng YES causes the pr�nter to pr�nt out the SPC values for the hardness results �n memory. These values �nclude number of tests, m�n�mum, max�mum, average, standard deviation, etc.

GRAPH (see sample printout at the end of this section)

If the YES button �s pressed, the Graph�cs pr�ntout feature generates a frequency d�str�but�on d�agram (h�stogram) show�ng the read�ngs obta�ned �n a certa�n lot grouped �n ranges5 w�th the �nd�cat�on of number of results �n each range.

These ranges are automat�cally scaled to the data and �nclude spec l�m�ts, control l�m�ts and mean. Pr�nt�ng of the results does not affect the stored values, as these can only be cleared by spec�fic command (or scale and cal�brat�on changes).

PRINT HISTORY (see sample printout at the end of this section)

If the YES button �s pressed the pr�nter pr�nts the header w�th lot sequence #, zero set #, cal�brat�on status, lo and h� tolerance sett�ngs. Then the d�splay asks:

HB1 HOW MANY?

The operator can select the number of tests he wants to be pr�nted. �f all the tests �n memory are needed, enter 9999, followed by ENTER key. The format of the pr�ntout w�ll d�splay the sequence number, the hardness scale, the test result, and the tolerance result for h�gh, low, or OK.

X‑BAR & R CHART (OPTIONAL) (see sample printout at the end of this section)

The X‑Bar & R Chart pr�nts these two stat�st�cal charts (at r�ght) for all the results stored �n memory. The X‑Bar (average) chart �s always pr�nted, wh�le the R (range) chart �s pr�nted only �f the average mode �s �n effect. If the results �n memory are m�xed s�ngle read�ngs and averaged read�ngs, the charts w�ll show zero range for the s�ngle read�ngs.

RESULTS/VALUES ONLY

These two funct�ons toggle depend�ng on wh�ch �s selected. If “PRINT RESULTS?” appears on the d�splay, select�ng Yes w�ll cause the Results pr�nt funct�on to be act�vated. The next t�me the operator selects the PRINT Key the d�splay w�ll show VALUES ONLY.

When the RESULTS funct�on �s confirmed by press�ng YES when “PRINT RESULTS” appears on the d�splay, the results of each test w�ll be pr�nted after the tester performs the test along w�th values for lot number, sequence number, zero d�splacement, cal�brat�on status (w�th an aster�sk), and tolerance sett�ngs. For a descr�pt�on of th�s data str�ng see the Test Head Spec�ficat�ons sect�on.

When the “VALUES ONLY” funct�on �s confirmed by press�ng YES when the “VALUES ONLY” prompt appears on the d�splay, the test value alone �s pr�nted w�thout any tolerances or other descr�pt�ve �nformat�on. Th�s can be useful when the data �s be�ng exported to a computer.

ON DEMAND

Th�s funct�on allows the operator to pr�nt the results of the last test by press�ng the YES button. The pr�ntout w�ll appear �n the H�story Data pr�ntout form.

If two tests are performed before the YES button �s pressed the pr�or test w�ll not be pr�nted.

The On Demand funct�on �s deact�vated by enter�ng any other “Pr�nt’’ funct�on, or answer�ng NO to all Pr�nt modes.

PRINT OFF

Turns off pr�nt�ng from the PRINT Results or Values only Modes. Only appears �n sequence �f Results or Values Only Modes are turned on.

TRACE

If YES �s entered at th�s po�nt the Trace pr�nt funct�on �s act�vated, (�f the PRINT key funct�on has been enabled). Th�s funct�on w�ll automat�cally cause results to be pr�nted after each test. It w�ll also cause every message wh�ch appears on the d�splay to be pr�nted. Whenever the Trace funct�on �s act�vated, the message wh�ch was on the d�splay before

PLEASE NOTE: If the Trace funct�on �s act�vated, �t w�ll rema�n act�vated even �f the secur�ty code procedure �s later repeated w�thout enabl�ng the PRINT key aga�n. If the PRINT key �s not enabled, the Trace funct�on w�ll not appear as the operator v�ews the Pr�nt funct�on sequence so �t cannot be deact�vated. If th�s occurs, and the operator wants to stop the Trace funct�on, the secur�ty code procedure must be performed aga�n and the Pr�nt funct�on enabled. Then, after press�ng the PRINT key and return�ng to the Trace funct�on, wh�ch w�ll now be d�splayed, the operator must s�mply answer NO to the Trace funct�on.

SET BAUD RATE

If the YES button �s pressed, the d�splay shows the current baud rate sett�ng for the pr�nter output. The operator may then select 300, 1000, or 9600 baud and press the ENTER key. If any other value �s entered, “Incorrect Value” w�ll be d�splayed. Note: “Set Baud” w�ll not appear �f the PRINT key has not been enabled.

2.4.9 Mode Key Functions

There are 8 Mode funct�ons : T�me at Load, D�ameter/Br�nell Convers�on, M�n�mum Th�ckness, Cont�nuous‑On, Average On, D�ameter Results, D�sable H�story, Set Clock . These funct�ons ap‑pear �n sequence as the NO key �s pressed. All funct�ons need to be enabled w�th secur�ty code.

TIMED LOAD

Press�ng YES key enables the operator to v�ew the currently selected t�me‑at‑load. Press�ng ENTER key confirms that select�on. Enter�ng a new value followed by ENTER key changes the t�me‑at‑load. The t�med load can be set from 0 to 99 seconds. 99 seconds w�ll hold the test head down �ndefin�tely.

DIAMETER/BRINELL

If the tester �s d�splay�ng Br�nell values, press�ng the YES w�ll cause the �mpress�on d�ameter for the last test result to be calculated from the Br�nell number. An example of a d�ameter d�splay would be:

HB‑1 DIA = 3.05

Th�s d�splay shows the scale �s HB‑1 and a d�ameter �n m�ll�meters of 3.05. Th�s message w�ll be d�splayed unt�l the NO key or another funct�on key �s pressed. If the tester �s setup to d�splay d�ameter measurements then the tester w�ll d�splay “Br�nell?” and prov�de Br�nell value convers�ons.

MINIMUM THICKNESS

Press�ng YES w�ll cause the m�n�mum th�ckness value for the last test result to be d�splayed. Th�s value �s calculated as ten t�mes the d�splacement value. an example of th�s d�splay m�ght look l�ke;

HB‑1 MIN = .1251N

Th�s d�splay would �nd�cate the scale was HB1 and the m�n�mum th�ckness was .125 �nches. Th�s d�splay can g�ve the m�n�mum th�ckness value �n m�ll�meters (as �nd�cated by an “MM” �nstead of “IN”). To sw�tch back and forth from m�ll�meters to �nches press the YES key. Th�s value w�ll rema�n on the d�splay unt�l the NO key or another funct�on key �s pressed.

TRANSDUCER_CHECK

Press�ng YES w�ll cause the Cont�nuous D�splay mode funct�on to be act�vated. Th�s funct�on w�ll cause the transducer �nput value to be d�splayed. For more �nformat�on refer to the Transducer Sect�on under Load and Penetrat�on Depth Gaug�ng.

AVERAGE

Press�ng YES to the “AVG ?” query w�ll select the Average mode funct�on. Th�s funct�on w�ll cause the pr�nter to pr�nt out the results from a spec�fied number of tests made on a spec�men along w�th the range and average and also d�splay the average on the readout. These average results w�ll be stored under a s�ngle sequence number, and the �nd�v�dual test w�ll not be stored. After select�ng th�s funct�on the first d�splay w�ll be:

HB‑1 HOW MANY?

Enter any number from 2 to 10. Then the d�splay changes to:

HB‑1 READY

The operator performs the first ser�es of tests. If the average of three tests was selected then the pr�ntout would occur after the three tests and would appear as follows:

1 200 204 205RANGE = 5AVG = 203 *H

At th�s t�me an �nd�cat�on of *H or *L �f the average result �s the h�ghest or lowest so far �n the sequence �n a g�ven ser�es of averaged tests, the last *L or *H pr�nted �nd�cates the h�ghest or lowest �n the c�ted ser�es. HI, LO, or OK tolerance �nd�cat�ons also are pr�nted �f tolerances have been entered.

To turn off the AVERAGE funct�on, press the MODE key, press the YES key to the AVG? query, and select “1” to the query for “HOW MANY”.

PLEASE NOTE: The average value �s calculated to the first dec�mal. There �s no round off from the 2nd dec�mal place value.

All TOTAL, GRAPH, and STAT funct�ons use the average value �n the�r calculat�ons and pr�ntouts. None of the �nd�v�dual results are stored so only the averages are pr�nted. (Opt�onal programm�ng �s ava�lable to store �nd�v�dual results.)

If the operator uses the CLEAR LAST funct�on dur�ng or after the sequence of three tests, the last test result (not the last average) �s deleted. If the last test �n a ser�es �s to be deleted the pr�nter w�ll repeat the pr�ntout us�ng the same sequence number.

DIAMETER RESULTS

Select�ng th�s funct�on toggle between DIAMETER and BRINELL to cause all results to appear and be d�splayed and pr�nted as d�ameter measurements or Br�nell values

3.3 General Description

The test head conta�ns the load and d�mens�onal gaug�ng sensors and a number of sw�tches to control the test parameters. �t �s connected by bolts to the hydraul�c cyl�nder.

Several electron�c cables are also attached to the sensors on the test head. A yellow sh�eld covers these sensors and prov�des access for serv�ce. The sensors run to the eletron�c readout box and the top of the stand frame.

The sensors cons�st of a preload sw�tch on the back of the test head, the LVD transducer to measure the depth of �ndentat�on, the safety dev�ce, and the load cell to control the test load. A sensor on the stand column �s the Home/Overtravel sensor. At the top of the stand �s an Emergency return button wh�ch can automat�cally cause the hydraul�cs to retract.

3.5 Routine Procedures

3.5.1 Indenters and Shroud Removal/Install

The �ndenters and �ndenters shroud may be removed us�ng an allen wrench and [2] open box wrenches. The shroud �s mounted w�th three allen screws. T�ghten screws evenly; there �s a gap between the bottom of the head and the Chromed Shroud r�ng (See below).

WARNING: When chang�ng the �ndenter, hold the �ndenter holder w�th a second wrench �n order to avo�d damage to the �nternal head bear�ngs. Refer to p�cture below. The �ndenter cons�sts of a tungsten carb�de ball welded to a threaded shaft. The standard shroud uses a spr�ng‑loaded nose p�ece to t�lt for test�ng on tapered spec�mens. After remov�ng the shroud, the �ndenters may be removed by unscrew�ng �t w�th the 13mm wrench �n the accessory k�t.

Note: There �s a gap between the r�ng that holds the shroud �n place and the square plate where the screws thread �nto.

Note: Make certa�n the �ndenters �s firmly threaded �n place.

3.7.2 Safety Device Checking and Adjustment

Th�s feature detects mater�als that are too soft to be tested (below HB 50), and w�ll retract the head �f the operator should get h�s hand under the �ndenter shroud. (CAUTION: Th�s safety dev�ce w�ll help reduce the degree of �njury to an operator, but severe �njury may st�ll result.] F�xture the part properly so that operator does not have to keep h�s hands �n the �ndenter area.

To check �ts funct�on, put a double p�ece of cardboard on the anv�l and make a test. The �ndenter should make a small dent �n the cardboard and �mmed�ately retract w�thout punch�ng a hole through both layers. The tester can also be checked us�ng a test spec�men that has a hardness of under HB 50. �f adjustment �s needed, loosen the screw. To make the safety sw�tch more sens�t�ve, move the magnet that act�vates the sw�tch upwards, and v�ce versa.

3.7.3 LS2 - Preload Switch

(Contact factory before mak�ng adjustment.) Th�s sw�tch controls the preload s�gnal to the electron�cs to zero the preload read�ng and �n�t�ates the read�ng of the depth of penetrat�on at the full load pos�t�on. Its output �s normally h�gh (+5V DC), �t goes to 0 when act�vated.

The proper pos�t�on for th�s sw�tch �s �nd�cated by a number of checks. 1) Jog the test head down to the anv�l, stopp�ng just before contact�ng the test p�ece and cont�nue travel�ng downward unt�l the �ndenter contacts the test p�ece. At th�s po�nt the preload spr�ng starts to compress, and the preload sw�tch moves relat�ve to the preload sw�tch magnet by about 1/4" Watch the d�splay of the readout un�t for test cycle be�ng entered (the d�splay changes from prev�ous result to act�ve d�splay mode). Th�s trans�t�on should occur at 1/8" m�dway through the 1/4" total travel. Adjust preload magnet holder �f necessary.

3.7.4 Transducer

(See Photo/draw�ng for Load and Penetrat�on Depth Gag�ng)

Transducer: LVDT w�th +/‑ 1mm accurate travel and 0.001 mm resolut�on

The transducer �s located �n the test head under the yellow cover per the �llustrat�on (preceed�ng pages). It �s ver�fied for proper pos�t�on�ng by check�ng �ts output. To check the output, press the MODE key on the keypad, and move to the Transducer Check funct�on. (Refer to the Keypad Operat�on sect�on of the manual.) When the Transducer Check funct�on �s act�vated the d�splay w�ll show the transducer output. Th�s number tracks the pos�t�on of the �ndenter relat�ve to the shroud (or v�ce‑versa). Mov�ng the �ndenter shroud up and down should make the number change from below 1000 to above 7000. If th�s does not happen the transducer may be �n the �ncorrect pos�t�on. To reset �t, loosen the screw that clamps the transducer �nto pos�t�on and manually sl�de the transducer up or down. As the transducer moves the d�splay w�ll change. When the correct sett�ng �s reached at 4000 +/‑ 100, t�ghten the transducer screw. DO NOT OVER‑TIGHTEN. For transducer cal�brat�on, move the nosep�ece relat�ve to the �ndenter exactly 0.500 mm (use gage blocks �r a m�crometer screw) and the d�splay number should change by 1515 counts +/‑15. If adjustment �s needed, turn the potent�ometer "Z" on the analog board (see Electron�c Box D�agram Sect�on, Analog Board draw�ng).

3.7.5 Load Calibration

The load cal�brat�on �s the pr�mary ver�ficat�on s�nce �t �s a bas�c constant �n the Br�nell test. The load can be ver�fied us�ng a prov�ng r�ng or a test block. When us�ng the prov�ng r�ng, place a test block on top of the r�ng. Th�s prevents the r�ng from act�vat�ng the emergency dev�ce. The standard load �s 500 kg, Make certa�n the prov�ng r�ng �s properly placed on the anv�l �n a stable load�ng pos�t�on. W�th the mach�ne runn�ng properly, the load on the prov�ng r�ng should be w�th�n +/‑ 1% when the tester �s at full load.

Note: The nosep�ece adds 6.7 kg to the total test force. E�ther l�ft the nosep�ece or cons�der �t as part of the load and cal�brate the mach�ne at 506.7 kg.

A test block may also be used for �nd�rect ver�ficat�on of load. When us�ng the test block to cal�brate the load, take several tests and read the results opt�cally. (Do not use the results on the d�splay.) The d�fference between the m�n�mum and max�mum result should not be more than the range of the test block. If there �s a cons�stency problem, �t should be corrected before cal�brat�on �s attempted (see Troubleshoot�ng gu�de). If the results are cons�stent, take the average value and compare �t w�th the value on the block. It should be w�th�n +/‑ 1%. If load adjustment �s necessary, please use a prov�ng r�ng to check the load before mak�ng adjustments.

PLEASE NOTE: Keep �n m�nd that when us�ng a test block to cal�brate the load that other factors may offset the read�ng such as �naccuracy of the block �tself or �naccurate opt�cal read�ngs by operators. The best ver�ficat�on of the load �s w�th a prov�ng r�ng.
