WarningTo avoid electrical shock or fire if a test toolinput is connected to more than 42 V peak (30Vrms) or on circuits of more than 4800 VA:• Use only insulated voltage probes, test leads

and adapters supplied with the test tool, orindicated by Fluke as suitable for the Fluke190ScopeMeter series.

• Before use, inspect voltage probes, test leadsand accessories for mechanical damage andreplace when damaged.

• Remove all probes, test leads and accessoriesthat are not in use.

• Always connect the battery charger first to theac outlet before connecting it to the test tool.

• Do not connect the ground spring (figure 1,item f) to voltages higher than 42 V peak (30Vrms) from earth ground.

• Do not apply voltages that differ more than 600V from earth ground to any input whenmeasuring in a CAT III environment.Do not apply voltages that differ more than1000 V from earth ground to any input whenmeasuring in a CAT II environment.

• Do not apply voltages that differ more than 600V from each other to the isolated inputs whenmeasuring in a CAT III environment.Do not apply voltages that differ more than1000 V from each other to the isolated inputswhen measuring in a CAT II environment.

• Do not apply input voltages above the rating ofthe instrument. Use caution when using 1:1test leads because the probe tip voltage will bedirectly transmitted to the test tool.

• Do not use exposed metal BNC or banana plugconnectors.

• Do not insert metal objects into connectors.• Always use the test tool only in the manner

specified.Voltage ratings that are mentioned in the warnings, aregiven as limits for “working voltage”. They representV ac rms (50-60 Hz) for ac sinewave applications and asV dc for dc applications.

Overvoltage Category III refers to distribution level andfixed installation circuits inside a building.Overvoltage Category II refers to local level, which isapplicable for appliances and portable equipment.


6

The terms ‘Isolated’ or ‘Electrically floating’ are used inthis manual to indicate a measurement in which the testtool input BNC or banana jack is connected to a voltagedifferent from earth ground.

The isolated input connectors have no exposed metal andare fully insulated to protect against electrical shock.

The red and gray BNC jacks, and the red and black4-mm banana jacks can independently be connected to avoltage above earth ground for isolated (electricallyfloating) measurements and are rated up to 1000 VrmsCAT II and 600 Vrms CAT III above earth ground.

If Safety Features are Impaired

Use of the test tool in a manner not specified mayimpair the protection provided by the equipment.Before use, inspect the test leads for mechanical damageand replace damaged test leads!

Whenever it is likely that safety has been impaired, thetest tool must be turned off and disconnected from the linepower. The matter should then be referred to qualifiedpersonnel. Safety is likely to be impaired if, for example,the test tool fails to perform the intended measurementsor shows visible damage.

Recording Scope Waveforms In DeepMemory (Scope Record)The SCOPE RECORD function is a roll mode that logs one ortwo long waveforms. This function can be used to monitorwaveforms like motion control signals or the power-onevent of an Uninterruptable Power Supply (UPS). Duringrecording, fast transients are captured. Because of thedeep memory, recording can be done for more than oneday. This function is similar to the roll mode in manyDSO’s but has deeper memory and better functionality.

Starting a Scope Record Function1 Apply a signal to the red BNC input A.

2 From the Recorder main menu,highlight Scope Record.

3 Start the recording.

The waveform moves across the screen from right to leftlike a normal chart recorder. (See Figure 18.)

Figure 18. Recording Waveforms

Observe that the top of the screen displays the following:

• Time from start at the top of the screen.

• The status at the bottom of the screen which includesthe time/div setting as well as the total timespan thatfits the memory.

Note

For accurate recordings it is advised to let theinstrument first warm up for five minutes.


34

Displaying Recorded DataIn Normal view, the samples that roll off the screen arestored in deep memory. When the memory is full,recording continues by shifting the data in memory anddeleting the first samples out of memory.

In View All mode, the complete memory contents aredisplayed on the screen.

Figure 20. Triggered Single Sweep Recording

Analyzing a TrendPlot or Scope RecordFrom a Scope TrendPlot or Scope Record you can usethe analysis functions CURSORS and ZOOM to performdetailed waveform analysis. These functions aredescribed in Chapter 4: “Using Replay, Zoom andCursors”.

37

Chapter 4Using Replay, Zoom and Cursors

About this ChapterThis chapter covers the capabilities of the analysisfunctions Cursor, Zoom, and Replay. These functionscan be used with one or more of the primary functionsScope, TrendPlot or Scope Record.

It is possible to combine two or three analysis functions.A typical application using these functions follows:

• First replay the last screens to find the screen ofspecial interest.

• Then zoom in on the signal event.

• Finally, make measurements using the cursors.

Replaying the 100 Most Recent ScopeScreensWhen you are in scope mode, the test tool automaticallystores the 100 most recent screens. When you press theHOLD key or the REPLAY key, the memory contents arefrozen. Use the functions in the REPLAY menu to “go backin time” by stepping through the stored screens to find thescreen of your interest. This feature lets you capture andview signals even if you did not press HOLD.


38

Replaying Step-by-StepTo step through the last scope screens, do the following:

1 From scope mode, open theREPLAY menu.

Observe that the trace is frozenand that REPLAY appears at thetop of the screen (see Figure 21).

2 Step through the previousscreens.

3 Step through the next screens.

Observe that the bottom of the waveform area displaysthe replay bar with a screen number and related timestamp:

Figure 21. Replaying a Waveform

The replay bar represents all 100 stored screens inmemory. The icon represents the picture beingdisplayed on the screen (in this example: SCREEN -84). Ifthe bar is partly white, the memory is not completely filledwith 100 screens.

From this point you can use the zoom and cursorfunctions to study the signal in more detail.

Using Replay, Zoom and CursorsReplaying the 100 Most Recent Scope Screens 4

39

Replaying ContinuouslyYou can also replay the stored screens continuously, likeplaying a video tape.

To replay continuously, do the following:

1 From Scope mode, open theREPLAY menu.

Observe that the trace is frozenand REPLAY appears at the top ofthe screen.

2 Continuously replay the storedscreens in ascending order.

Wait until the screen with the signal event of interestappears.

3 Stop the continuous replay.

Turning Off the Replay Function

4 Turn off REPLAY.

Capturing 100 Intermittents AutomaticallyWhen you use the test tool in triggered mode, 100triggered screens are captured. This way you could usePulse Triggering to trigger and capture 100 intermittentglitches or you could use External Triggering to capture100 UPS startups.

By combining the trigger possibilities with the capability ofcapturing 100 screens for later replay, you can leave thetest tool unattended to capture intermittent signalanomalies.

For triggering, see Chapter 5: “Triggering on Waveforms”.


40

Zooming in on a WaveformTo obtain a more detailed view of a waveform, you canzoom in on a waveform using the ZOOM function.

To zoom in on a waveform, do the following:

1 Display the ZOOM key labels.

Observe that the trace is frozen,HOLD appears at the top of thescreen, and the waveform ismagnified.

2 Enlarge (decrease the time/div)or shrink (increase the time/div)the waveform.

3 Scroll. A position bar displays theposition of the zoomed part inrelation to the total waveform.

TipEven when the key labels are not displayed atthe bottom of the screen, you can still use thearrow keys to zoom in and out.

Figure 22. Zooming in a Waveform

Observe that the bottom of the waveform area displaysthe zoom ratio, position bar, and time/div (see Figure 22).The zoom range depends on the amount of data samplesstored in memory.

From this point you can use the cursor function for furthermeasurements on the waveform.

Using Replay, Zoom and CursorsZooming in on a Waveform 4

41

Displaying the Zoomed WaveformThe VIEW ALL feature is useful when you quickly need tosee the complete waveform and then return to thezoomed part.

4 Display the complete waveform.

Press repeatedly to toggle between the zoomed partof the waveform and the complete waveform.

Turning Off the Zoom Function

5 Turn off the ZOOM function.


42

Making Cursor MeasurementsCursors allow you to make precise digital measurementson waveforms. This can be done on live waveforms,recorded waveforms, and on saved waveforms.

Using Horizontal Cursors on a WaveformTo use the cursors for a voltage measurement, do thefollowing:

1 From scope mode, display thecursor key labels.

2 Press to highlight . Observethat two horizontal cursors aredisplayed.

3 Highlight the upper cursor.

4 Move the upper cursor to thedesired position on the screen.

5 Highlight the lower cursor.

6 Move the lower cursor to thedesired position on the screen.

NoteEven when the key labels are not displayed atthe bottom of the screen, you still can use thearrow keys. This allows full control of bothcursors while having full screen view.

Figure 23. Voltage Measurement with Cursors

The screen shows the voltage difference between the twocursors and the voltage at the cursors. (See Figure 23.)

Use horizontal cursors to measure the amplitude, high orlow value, or overshoot of a waveform.

Using Replay, Zoom and CursorsMaking Cursor Measurements 4

43

Using Vertical Cursors on a WaveformTo use the cursors for a time measurement, do thefollowing:


2 Press to highlight . Observethat two vertical cursors aredisplayed. Markers (—) identifythe point where the cursors crossthe waveform.

3 If necessary, choose the trace:TRACE A ,B, or M (Mathematics).

4 Highlight the left cursor.

5 Move the left cursor to thedesired position on the waveform.

6 Highlight the right cursor.

Figure 24. Time Measurement with Cursors

7 Move the right cursor to thedesired position on the waveform.

The screen shows the time difference between thecursors and the voltage difference between the twomarkers. (See Figure 24.)

8 Turn off the cursors.


44

Using Cursors on a A+B, A-B or A*B WaveformCursor measurements on a A*B waveform give a readingin Watts if input A measures (milli)Volts and input Bmeasures (milli)Amperes.

For other cursor measurements on a A+B, A-B or A*Bwaveform no reading will be available if the input A andinput B measurement unit are different.

Making Rise Time MeasurementsTo measure rise time, do the following:


2 Press to highlight (rise time).Observe that two horizontalcursors are displayed.

3 If only one trace is displayed,select MANUAL or AUTO (thisautomatically does steps 4 to 6).For multiple traces select therequired trace A, B, or M (if amath function is active).

4 Move the upper cursor to 100%of the trace height. A marker isshown at 90%.

5 Highlight the other cursor.

6 Move the lower cursor to 0% ofthe trace height. A marker isshown at 10%.

The reading shows the risetime from 10%-90% of thetrace amplitude.

Chapter 5Triggering on Waveforms

About this ChapterThis chapter provides an introduction to the triggerfunctions of the test tool. Triggering tells the test tool whento begin displaying the waveform. You can use fullyautomatic triggering, take control of one or more maintrigger functions (semi-automatic triggering), or you canuse dedicated trigger functions to capture specialwaveforms.Following are some typical trigger applications:

• Use the Connect-and-View™ function to have fullautomatic triggering and instant display of virtuallyany waveform.

• If the signal is unstable or has a very low frequency,you can control the trigger level, slope, and triggerdelay for a better view of the signal. (See nextsection.)

• For dedicated applications, use one of the fourmanual trigger functions:• Edge triggering• External triggering• Video triggering• Pulse Width triggering


46

Setting Trigger Level and SlopeThe Connect-and-View™ function enables hands-offtriggering to display complex unknown signals.

When your test tool is in manual range, do the following:

Perform an auto set. AUTO appearsat the top right of the screen.

Automatic triggering assures a stable display of virtuallyany signal.

From this point, you can take over the basic triggercontrols such as level, slope and delay. To optimizetrigger level and slope manually, do the following:

1 Display the TRIGGER key labels.

2 Trigger on either positive slope ornegative slope of the chosenwaveform.

3 Enable the arrow keys for manualtrigger level adjustment.

Figure 26. Screen with all Trigger Information

4 Adjust the trigger level.

Observe the trigger icon that indicates the triggerposition, trigger level, and slope.

At the bottom of the screen the trigger parameters aredisplayed. (See Figure 26.) For example, means that input A is used as the trigger source with apositive slope.

When no trigger is found, the trigger parameters appear ingray.

Triggering on WaveformsUsing Trigger Delay or Pre-trigger 5

47

Using Trigger Delay or Pre-triggerYou can begin to display the waveform some time beforeor after the trigger point has been detected. Initially, youhave 2 divisions of pre-trigger view (negative delay).

To set the trigger delay, do the following:

5 Hold down to adjust the triggerdelay.

Observe that the trigger icon on the screen moves toshow the new trigger position. When the trigger positionmoves left off of the screen, the trigger icon changes into

to indicate that you have selected a trigger delay.Moving the trigger icon to the right on the display givesyou a pre-trigger view.

In case of a trigger delay, the status at the bottom of thescreen will change. For example:

This means that input A is used as the trigger source witha positive slope. The 500.0 ms indicates the (positive)delay between trigger point and waveform display.

When no trigger is found, the trigger parameters appear ingray.

Figure 27. Trigger Delay or Pre-trigger View

Figure 27 shows an example of a trigger delay of 500 ms(top) and an example of pre-trigger view of 8 divisions(bottom).


48

Automatic Trigger OptionsIn the trigger menu, settings for automatic triggering canbe changed as follows. (See also Chapter 1: “Displayingan Unknown Signal with Connect-and-View”)


Note

The TRIGGER key labels can differ depending onthe latest trigger function used.

2 Open the Trigger Options menu.

3 Open the Automatic Triggermenu.

If the frequency range of the automatic triggering is set to> 15 Hz, the Connect-and-View™ function responds morequickly. The response is quicker because the test tool isinstructed not to analyze low frequency signalcomponents. However, when you measure frequencieslower than 15 Hz, the test tool must be instructed toanalyze low frequency components for automatictriggering:

4 Select > 1 HZ and return to themeasurement screen.

Triggering on WaveformsTriggering on Edges 5

49

Triggering on EdgesIf the signal is instable or has a very low frequency, useedge triggering to obtain full manual trigger control.

To trigger on rising edges of the input A waveform, do thefollowing:



3 Open the Trigger on Edge menu.

When Free Run is selected, the test tool updates thescreen even if there are no triggers. A trace alwaysappears on the screen.

When On Trigger is selected, the test tool needs a triggerto display a waveform. Use this mode if you want toupdate the screen only when valid triggers occur.

When Single Shot is selected, the test tool waits for atrigger. After receiving a trigger, the waveform is displayedand the instruments is set to HOLD.

In most cases it is advised to use the Free Run mode:

4 Select Free Run, jump to Noisereject Filter.

5 Set Noise reject Filter to Off.

Observe that the key labels at the bottom of the screenhave adapted to allow further selection of specific edgetrigger settings:


50

Triggering on Noisy WaveformsTo reduce jitter on the screen when triggering on noisywaveforms, you can use a noise rejection filter. Continuefrom step 3 of the previous example as follows:

4 Select On Trigger, jump to Noisereject Filter.

5 Set Noise reject Filter to On.

Observe that the trigger gap has increased. This isindicated by a taller trigger icon .

Making a Single AcquisitionTo catch single events, you can perform a single shotacquisition (one-time screen update). To set up the testtool for a single shot of the input A waveform, continuefrom step 3 again:

4 Select Single Shot.

5 Accept the settings.

The word WAITING appears at the top of the screenindicating that the test tool is waiting for a trigger. As soonas the test tool receives a trigger, the waveform isdisplayed and the instrument is set to hold. This isindicated by the word HOLD at top of the screen.

Triggering on WaveformsTriggering on Edges 5

51

The test tool will now have a screen like Figure 28.

6 Arm the test tool for a new singleshot.

TipThe test tool stores all single shots in the replaymemory. Use the Replay function to look at allthe stored single shots.

Figure 28. Making a Single Shot Measurement


52

Triggering on External WaveformsUse external triggering when you want to displaywaveforms on inputs A and B while triggering on a thirdsignal. You can choose external triggering with automatictriggering or with edge triggering.

1 Supply a signal to the red and black 4-mmbanana jack inputs. See Figure 29.

In this example you continue from the Trigger on Edgesexample. To choose the external signal as trigger source,continue as follows:

2 Display the TRIGGER (On Edges)key labels.

3 Select Ext (external) edge trigger.

Observe that the key labels at the bottom of the screenhave been adapted to allow selection of two differentexternal trigger levels: 0.12 V and 1.2 V:

54

Triggering on Video FramesUse FIELD 1 or FIELD 2 to trigger either on the first halfof the frame (odd) or on the second half of the frame(even).

To trigger on the second half of the frame, do thefollowing:

7 Choose FIELD 2.

The signal part of the even field is displayed on thescreen.

Triggering on Video LinesUse ALL LINES to trigger on all line synchronization pulses(horizontal synchronization).

7 Choose ALL LINES.

The signal of one line is displayed on the screen. Thescreen is updated with the signal of the next lineimmediately after the test tool triggers on the horizontalsynchronization pulse.

To view a specific video line in more detail, you can selectthe line number. For example, to measure on video line123, continue from step 6 as follows:

7 Enable video line selection.

8 Select number 123.

The signal of line 123 is displayed on the screen. Observethat the status line now also shows the selected linenumber. The screen is continuously updated with thesignal of line 123.

Triggering on WaveformsTriggering on Pulses 5

55

Triggering on PulsesUse pulse width triggering to isolate and display specificpulses that you can qualify by time, such as glitches,missing pulses, bursts or signal dropouts.

Detecting Narrow PulsesTo set the test tool to trigger on narrow positive pulsesshorter than 5 ms, do the following:

1 Apply a video signal to the red input A.



4 Select Pulse Width on A... toopen the Trigger on Pulse Widthmenu.

5 Select the positive pulse icon,then jump to Condition.

6 Select <t, then jump to Update.

7 Select On Trigger.

The test tool is now prepared to trigger on narrow pulsesonly. Observe that the trigger key labels at the bottom ofthe screen have been adapted to set the pulse conditions:


56

To set the pulse width to 5 ms, do the following:

7 Enable the arrow keys to adjustthe pulse width.

8 Select 5 ms.

All narrow positive pulses shorter than 5 ms are nowdisplayed on the screen. (See Figure 31.)

TipThe test tool stores all triggered screens in thereplay memory. For example, if you setup yourtriggering for glitches, you can capture 100glitches with time stamps. Use the REPLAY key tolook at all the stored glitches.

Figure 31. Triggering on Narrow Glitches

Triggering on WaveformsTriggering on Pulses 5

57

Finding Missing PulsesThe next example covers finding missing pulses in a trainof positive pulses. In this example it is assumed that thepulses have a 100 ms distance between the rising edges.If the time accidently increases to 200 ms, a pulse ismissing. To set the test tool to trigger on such missingpulses, let it trigger on gaps bigger than about 150 ms.Do the following:



3 Select Pulse Width on A... toopen the Trigger on Pulse Widthmenu.

4 Select the positive pulse icon totrigger on the gap between thepositive pulses, then jump toCondition.

5 Select >t, then jump to Update.

Using the Independently FloatingIsolated InputsYou can use the independently floating isolated inputs tomeasure signals that are independently floating from eachother.

Independently floating isolated inputs offer additionalsafety and measurement capabilities compared to inputswith common references or grounds.

Measuring Using Independently Floating IsolatedInputsThe test tool has independently floating isolated inputs.Each input section (A, B, External Trigger / DMM) has itsown signal input and its own reference input. Thereference input of each input section is electricallyisolated from the reference inputs of the other inputsections. The isolated input architecture makes the testtool about as versatile as having three independentinstruments. The advantages of having independentlyfloating isolated inputs are:

• It allows simultaneous measurement of independentlyfloating signals.

• Additional safety. Since the commons are not directlyconnected, the chance of causing short circuit whenmeasuring multiple signals is greatly reduced.

• Additional safety. When measuring in systems withmultiple grounds, the ground currents induced arekept to a minimum.

Because the references are not connected together insidethe test tool, each reference of the used inputs must beconnected to a reference voltage.

Independently floating isolated inputs are still coupled byparasitic capacitance. This can occur between the inputreferences and the environment, and between the inputreferences mutually (see Figure 44). For this reason, youshould connect the references to a system ground oranother stable voltage. If the reference of an input isconnected to a high speed and / or high voltage signal,you should be aware of parasitic capacitance.(See Figures 44, 45, 46 and 47.)

Saving Battery LifeWhen operated on the battery (no battery chargerconnected), the test tool conserves power by shutting itselfdown. If you have not pressed a key for at least 30 minutes,the test tool turns itself off automatically.

Note

If the power adapter is connected, there is noautomatic power shutdown.

Automatic power shutdown will not occur if TrendPlot orScope Record is on, but the backlight will dim. Recordingwill continue even if the battery is low, and retention ofmemories is not jeopardized.

Setting the Power Down TimerInitially the power shutdown time is 30 minutes. You can setthe power shutdown time to 5 minutes as following:



3 Open the Battery Save Optionsmenu.

4 Select 5 Minutes.


76

Changing the Auto Set OptionsWith the next procedure you can choose how auto setbehaves when you press the AUTO (auto set) key.



3 Open the Auto Set Adjust menu.

If the frequency range is set to > 15 Hz, the Connect-and-View function responds more quickly. The response isquicker because the test tool is instructed not to analyzelow frequency signal components. However, when youmeasure frequencies lower than 15 Hz, the test tool mustbe instructed to analyze low frequency components forautomatic triggering:

4 Select Signal > 1 Hz, then jumpto Coupling.

With the coupling option you can choose how auto setbehaves. When you press the AUTO (auto set) key, thecoupling can either be set to dc or left unchanged:

5 Select Unchanged.

Note

The auto set option for the signal frequency issimilar to the automatic trigger option for thesignal frequency. (See Chapter 5: “AutomaticTrigger Options”). However, the auto set optiondetermines the behavior of the auto set functionand shows only effect when you press the autoset key.

Chapter 8Maintaining the Test Tool

About this ChapterThis chapter covers basic maintenance procedures thatcan be performed by the user. For complete service,disassembly, repair, and calibration information, see theService Manual. You will find the part number of theService Manual in the section “Parts and Accessories” inthis chapter.

Cleaning the Test ToolClean the test tool with a damp cloth and a mild soap. Donot use abrasives, solvents, or alcohol. These maydamage the text on the test tool.

Storing the Test ToolIf you are storing the test tool for an extended period oftime, charge the NiMH (Nickel-Metal Hydride) batteriesbefore storing.


78

Charging the BatteriesAt delivery, the NiMH batteries may be empty and must becharged for 4 hours (with the test tool turned off) to reachfull charge. When fully charged, the batteries provide4 hours of use.

When battery power is used, the battery indicator at thetop of the screen informs you about the condition of thebatteries. The battery symbols are: . Thesymbol indicates that there are typically five minutesof operating time left.

To charge the batteries and power the instrument, connectthe battery charger as shown in Figure 49. To charge thebatteries more quickly, turn off the test tool.

Caution

To avoid overheating of the batteries duringcharging, do not exceed the allowableambient temperature given in thespecifications.

Note

No damage will occur if the charger is connectedfor long periods, e.g., during the weekend. Theinstrument then automatically switches to tricklecharging.

Figure 49. Charging the Batteries

Maintaining the Test ToolExtending Battery Operation Time 8

79

Extending Battery Operation TimeTypically, NiMH batteries always meet the specifiedoperating time. However, if the batteries have beenextremely discharged (for example, when empty batterieswere stored for a long period) it is possible that the batterycondition has deteriorated.

To keep the batteries in optimal condition, observe thefollowing guidelines:

• Operate the test tool on batteries until the symbolappears at the bottom of the screen. This indicatesthat the battery level is low and that the NiMHbatteries need to be recharged.

• To obtain optimal battery condition again, you canrefresh the batteries. During a battery refresh, thebatteries will be fully discharged and charged again.A complete refresh cycle takes about 12 hours andshould be done about four times a year. You can checkthe latest battery refresh date. See section “DisplayingCalibration Information”.

To refresh the battery, make sure that the test tool is linepowered and proceed as follows:



A message appears asking whether you want to start therefresh cycle now.

3 Start the refresh cycle.

Do not disconnect the battery charger during therefresh cycle. This will interrupt the refresh cycle.

Note

After starting the refresh cycle, the screen will beblack.


80

Replacing the NiMH Battery Pack BP190Usually it should not be necessary to replace the batterypack. However, if replacement is needed, this should bedone by qualified personnel only. Contact your nearestFluke center for more information.

Calibrating the Voltage ProbesTo meet full user specifications, you need to adjust thered and gray voltage probes for optimal response. Thecalibration consists of a high frequency adjustment and adc calibration for 10:1 probes. The dc calibration is notpossible for 100:1 probes.

This example shows how to calibrate the 10:1 voltageprobes:

1 Display the input A key labels.

2 Open the Probe on A menu.

3 Select Voltage, then jump toAttenuation.

Figure 50. Adjusting Voltage Probes

If the 10:1 option is already selected, proceed with step 5.

4 Select 10:1, then return.

Maintaining the Test ToolCalibrating the Voltage Probes 8

81

Repeat steps 2 and 3 and proceed as follows:

5 Select Probe Cal with the arrowkeys, then accept.

A message appears asking you whether to start the 10:1probe calibration.

6 Start the probe calibration.

A message appears telling you how to connect the probe.Connect the red 10:1 voltage probe from the red input Ajack to the red banana jack. Connect the reference lead tothe black banana jack. (See Figure 50.)

7 Adjust the trimmer screw in theprobe housing until a pure squarewave is displayed.

8 Continue with DC calibration.Automatic DC calibration is onlypossible for 10:1 voltage probes.

The test tool automatically calibrates itself to the probe.During calibration you should not touch the probe. Amessage indicates when the DC calibration hascompleted successfully.

9 Return.

Repeat the procedure for the gray 10:1 voltage probe.Connect the grey 10:1 voltage probe from the grey input Bjack to the red banana jack. Connect the reference lead tothe black banana jack.

Note

When using 100:1 voltage probes, choose 100:1attenuation to perform a HF adjustment.Automatic dc calibration is not possible with thisprobe type.


82

Displaying Calibration InformationYou can display version number and calibration date:


2 Open the Version & Calibrationmenu.

The screen gives you information about the modelnumber with software version, the calibration number withlatest calibration date, and the latest battery refresh date.

3 Return.

Recalibration must be carried out by qualified personnel.Contact your local Fluke representative for recalibration.
