INTRODUCTION

1


The Intoxilyzer® S-D5 is the latestin the CMI, Inc. line of handheld

quantitative breath alcohol testing instruments. It can beused for law enforcement, workplace safety and medicalpurposes and is the successor to the popular S-D2model, thousands of which have been used worldwidefor several years. Unlike the S-D2, which requiresmanual operation, the S-D5 features an easy-to-useautomatic sampling system. The S-D5 is just one of therange of instruments manufactured by CMI, Inc. forbreath alcohol testing purposes.

The Intoxilyzer® S-D5 is accurate and reliable, allowing acomplete breath test procedure to be conducted in about30 seconds.

This manual describes the operation, maintenance,calibration check, and calibration adjustment of the S-D5.This manual should be read completely and fullyunderstood by each operator prior to testing a subject. Itis further recommended that operators practice thebreath testing process before giving an actual “in thefield” test.

2


The Intoxilyzer® S-D5 usesan electrochemical fuel cell,containing two platinumelectrodes, to detect and measure theconcentration of alcohol vapor in expired breath.When breath is drawn into this fuel cell, by meansof the sampling system, a small voltage isgenerated in proportion to its breath alcoholconcentration. This fuel cell is fed to an electronicamplifier and displayed on a digital meter (lightemitting diode).

The instrument is simple to operate and may beused as often as required, provided that a suitabledelay is allowed between successive tests. Thistime delay allows the fuel cell to clear itself ofalcohol and prevents the possibility of additivereadings. If no alcohol is present in a test, a secondtest may be analyzed immediately, since the fuelcell voltage is already at zero. Unless the breathalcohol level of the subject is very high, theinstrument will generally be clear enough to receiveand analyze the second sample in less than twominutes.

PRINCIPLES OFOPERATION

INSTRUMENT FEATURES

1) Disposable Mouthpiece

This is attached to the sampling port. Forhygenic reasons, mouthpieces are suppliedseparately packed and are disposable. A newmouthpiece must be used for each breath test.This minimizes health concerns and preventscross-sample alcohol contamination. Themouthpiece used on the Intoxilyzer® S-D5 is thesame as used on the Intoxilyzer® S-D2.

2) Function Button “A”

The uppermost button is used for variousfunctions described in this manual

3) Function Button “B” (On/Off switch)

Depress once to activate the unit. The lowerbutton is used for functions describedin this manual. Function button “B” is also usedto turn off the unit by holding it down for threeseconds until the display shows “Off”.

4) Digital Display

Provides on-screen directions to the instrumentoperator and indications of the subject’s breathalcohol concentration. Illuminates in bright redLED and at night for use in dark conditions.

5) Beeper

Provides audible warning messages to theoperator.

PRELIMINARY DONOR QUESTIONING

Ask the subject when he/she last took anything bymouth. Some foods and even “non-alcoholic” drinksmay contain traces of alcohol, which the subject maylater claim affected the result of the test through a“mouth alcohol” effect. To prevent this, whereverpossible, insure that a delay of about 20 minutes haselapsed since the subject took anything by mouth—even medicines which may contain alcohol.

Do not even allow the subject a glass of water prior tothe test since this will cool the mouth and dilute thesaliva, temporarily reducing the amount of alcohol in thebreath, and, consequently, the instrument reading. A

Although the Intoxilyzer® S-D5 isextremely simple to operate, it isimportant that the following

procedure is used each time a breath test is given.Deviation from the proper procedure will not generallyaffect the result of a test. However, the integrity andcapability of an operator, and even the legality of anyresulting action, could be questioned and brought intodoubt if it is found later that the operator did not followthe proper testing procedure. This is true even if the testsubject was not analytically prejudiced by it.

SUBJECTBREATH

TEST


1) TURN INSTRUMENT “ON”

Switch the instrument on by pressing Function Button“B” and wait for “blo” to be displayed which isshown for only a brief time to conserve battery power.The decimal point will then flash.

2) ATTACH MOUTHPIECE

You can then attach a new disposable mouthpiece tothe sampling port. The mouthpiece can be attached toblow from either side of the unit. The hole in themouthpiece will fit snugly around the sampling port onthe top of the S-D5 and snap into place.

6


delay of at least two minutes should take placebetween the time the donor last smoked and the test.

DETAILED PROCEDURE

This section describes how the Intoxilyzer®

S-D5 is used in a breath test.

The mouthpiece can beattached to blow fromeither side of the unit. Dowhatever is mostcomfortable.

7

3) INSTRUCT THE SUBJECT

Instruct the subject to take adeep breath and to blow intothe lipped end of the mouth-piece at a steady pace untilyou say “stop.” During thetime when the subject isblowing, the S-D5 will display“Flo”.

4) SUBJECT PROVIDESSUFFICIENT SAMPLE

You can instruct the subject tostop blowing when you hear aclick and the unit begins toanalyze the sample (4-6seconds).

5) OBSERVE READING

If alcohol is detected, thereading will rise incrementallyon the display until it reachesits peak value. If the result isnegative, the display willquickly read “.000”.

6) DISCARD MOUTHPIECE

After the final reading ismade, remove the mouth-piece and discard. Never usethe same mouthpiece forsubsequent tests on differentsubjects.

At this stage, the Intoxilyzer®


While the subject blows, “Flo” willappear on the display. This tellsyou the subject is providing asufficient sample of air foranalysis.

If alcohol is not detected in thesubject’s breath, the display willquickly read “.000”.

A WORD ABOUT MOUTHPIECES...

The Intoxilyzer® S-D5’s sampling port isdesigned specifically for the particularIntoxilyzer® S-D5 mouthpieces sold by CMI, Inc.It is strongly recommended that mouthpieces forthe Intoxilyzer® S-D5 be ordered from CMI at1-800-835-0690 or an authorized CMI distributor.

8

S-D5 will automatically reset itself to allow more breath teststo proceed. “Blo” will appear in the display when the unit isready for more tests. If a test result is positive, it may take afew minutes before the unit is ready for another test. Thistime will vary depending on the concentration of the positivetest.


DONOR REFUSALS AND FAILURES

If the subject is not able to provide a sufficient sample, oneof the following two messages will be displayed:

• “Vol” indicates that the subject provided asample that did not satisfy the breathsampling requirement

• “Suc” indicates the subject attempted tofoul the test by withdrawing his/her sample

In both cases, the S-D5 will be unable to analyze a sufficientsample of breath for a quantitative result. The operatorshould wait for “Blo” to be displayed before proceeding withanother try.

MANUAL SAMPLE

If the subject cannot provide a sufficient sample, the S-D5’smanual override feature makes it possible to still acquireand analyze a breath sample. While the subject is blowing,

simply press and release Function Button “A”. The S-D5will then sample the breath as provided. Note: Since themanual sample feature is controlled by the operator, thebreath sample might not be of the deep lung air equivalentthat the automatic sampling mode requires. Because ofthis, the manual sample result might not reflect the trueBAC of the subject.

LAST TEST RECALL

The S-D5 can recall from its memory the last breath testrecord. Simply press and release Function Button “B” toshow the last test result value. If the value shown is “no”,this indicates that the previous test was aborted because ofthe “Vol” or “Suc” conditions described above.

CALIBRATIONREQUIREMENTS:

USE OF THEDRY GAS

STANDARD

The Intoxilyzer® S-D5 uses an electrochemicalfuel cell to detect and measure the concentrationof alcohol in expired breath. The sensitivity of theinstrument changes slowly with time, due to agingof the platinum electrode within the fuel cell. Thischange in sensitivity is very slight and calibrationwill not normally change significantly over a six-month or longer period.

Monthly calibration checks are recommended todetermine when calibration adjustment is needed.

Either a dry gas standard or wet-bath simulatormay be used to generate the standard alcoholvapor required.

THE ALCOHOL STANDARD

Calibration checks and adjustments can beconveniently done using a dry gas standard. Thisconsists of a mixture of alcohol in air or nitrogen.

The quantity of alcohol in the gas is accuratelyknown and is shown on the label. Therefore, when

10


11

the instrument is calibrated using a dry gas standard,subsequent breath tests will indicate the subject’s bloodalcohol concentration (BAC).

Dry gas standards are supplied in one of four ranges,each range based around a legal limit which is in wideuse: .040% BAC, .045% BAC, .085% BAC and .105%BAC. For calibration above 3,000 feet, use a gas value of.085 or greater.

THE GAS STANDARD

The gas canister is a high-pressure, disposable cylinderfitted with a regulator. Cylinders are available in two sizes,containing enough gas for approximately 100 or 300calibration checks or adjustments.

The label on each cylinder is marked with an expirationdate. The gas should not be used after that time due todeviation of alcohol concentration of the gas outside theanalytical specifications of the instrument.

When the cylinder is empty or time-expired, the regulatorcan be safely unscrewed from the cylinder and retained foruse with a new cylinder. After venting all pressure, the oldcylinder can then be disposed or recycled.

USING A DRY GAS STANDARD AT HIGH ALTITUDE

The concentration of alcohol in the dry gas standard iscalculated and carefully controlled to give the correct vaporconcentration when the cylinder is used at sea level atnormal atmospheric pressure. At lower atmosphericpressures, the concentration of alcohol in the vapor leavingthe cylinder will be less. The change in alcoholconcentration due to normal atmospheric pressure changesat sea level is so small as to be negligible, but if the dry gasstandard was used at a high altitude, significant errorswould result if suitable corrections were not made.

It should be emphasized that the sensitivity of the

ALTITUDE CORRECTION CHART


13

Intoxilyzer® S-D5 itself to alcohol is not affected bychanges in atmospheric pressure; it is only theconcentration of the alcohol in the vapor from the dry gasstandard that is affected.

The Altitude Correction Chart on the preceding page givesthe correction factors which should be applied to thestated dry gas value when calibration checks oradjustments are made at various altitudes above sealevel.

Correction factor sample:

Suppose the dry gas standard you are usinghas a value of .045% BAC at sea level, butit is being used at an altitude of 500 feet.Using the chart on page 16, the correctionfactor would be (0.981). Therefore, thecorrected value of the dry gas standardwould now be (.045 x .981 = .044% BAC).

USE OF A WET BATH SIMULATOR

If required, a wet bath simulator can be used instead of adry gas standard to perform calibration checks andadjustments on the Intoxilyzer® S-D5.

A wet bath simulator should be used according to its owninstructions. Pay particular attention to the alcoholicstrength and temperature of the solution used.

A mouthpiece should be attached to the simulator outlet fordirect attachment to the sampling port on the instrument.A flow rate of air of about 1.5-2 liters per second should beused. Any higher rate may result in the formation of anaerosol and lead to excessive cooling of the solution itself.

The simulator vapor must be allowed to pass through themouthpiece for at least ten seconds before the sample is“taken” for analysis.

CALIBRATIONCHECK

PROCEDURE

The calibration check procedureinsures that the Intoxilyzer®

S-D5 is reading alcohol levelscorrectly and alerts the operatorthat a calibration adjustment isneeded. It is recommended that the instrument’scalibration be checked once per month.

DETAILED PROCEDURE

1) ENTER THE CALIBRATION CHECK MODE

Switch the instrument on bypressing Function Button“B”. As the S-D5 isperforming its startup selftest—upon the third digitdisplaying an “8”, pressand release FunctionButton “A”. The instrumentwill then enter its“calibration modes” cycle.Use Function Button “B” tocycle between showing“CAL” and “CHC”. Whenthe display is showing“CHC”, select this optionby pressing and releasingFunction Button “A”.

After entering the calibrationmodes, the unit will cyclebetween showing “CAL” and“CHC”. When “CHC” isdisplayed, enter the calibrationcheck mode by pressingFunction Button “A”.


15

2) CHOOSE BETWEEN DRY GAS STANDARD OR WETBATH SOLUTION

You now have a choice of using either dry gas standard orwet bath solution to perform the calibration check. To cyclebetween these modes, “Gas” and “Sol”, press FunctionButton “B”. Once your chosen calibration source isdisplayed, press and release Function Button “A” toconfirm.

3) DISPENSE THE CALIBRATION STANDARD

The instrument willthen ready itssampling mechanismfor calibration whichwill take a fewseconds. Whenready, the decimalpoint on the bottomleft of the display willflash at a steady rate.Dispense thecalibration standardthrough a newmouthpiece attached to the sampling port for a period of atleast five seconds. While the calibration standard is stillflowing, press and release Function Button “A” to samplethe standard and perform the check. The result will bedisplayed.

Once the calibration check process is completed, theS-D5 will return to the “calibration check mode” and shouldbe switched off by pressing Function Button “B”.

If the calibration check shows the instrument is outside theacceptable range of the calibration standard, a calibrationadjustment should be done using the procedure describedin the next section.

Dispense the calibration standard (drygas standard shown) into the unitthrough a mouthpiece for at least fiveseconds. Press Function Button “A” tosample the standard.


16

Calibration adjustment isrequired when a calibrationcheck indicates theIntoxilyzer® S-D5 hasdeviated more than ±.005BAC from a known standardof alcohol vapor. During thecalibration adustmentprocedure, the Intoxilyzer®

S-D5 will automatically adjust its fuel cell tocompensate for any change in sensitivity of the fuelcell detector over a period of time. Adjustment shouldnot normally be required more than two or three timesper year.

THE DRY GAS CALIBRATION VALUE

Since the fuel cell detector responds linearly to theconcentration of alcohol vapor in the standard, theactual value of the dry gas standard used forcalibration is not important, provided that theinstrument is actually calibrated to this value.

DETAILED PROCEDURE

The calibration adjustment process assumes threeconditions:

• The instrument has not analyzed a sample ofalcohol within the past hour,

• The instrument is in its normal operatingtemperature range, and

• The battery does not need replacement.

press Function Button “B”. Once your chosencalibration source is being displayed, press and releaseFunction Button “A” to confirm.

4) DISPENSE THE CALIBRATION STANDARD

The S-D5 will then ready its sampling mechanism forcalibration which will take a few seconds. When ready,the decimal point on the bottom left of the display willflash at a steady rate. Dispense the calibration standardthrough a new mouthpiece attached to the sampling portfor a period of at least five seconds. While thecalibration standard is still flowing, press and releaseFunction Button “A” to sample the standard and thenstop the calibration standard flow.

Once the calibration process is complete, theinstrument will return to the “calibration modes.” YourS-D5 is now calibrated and should be switched offmanually using Function Button “B”.


The following information, ifapplied to the operation ofyour Intoxilyzer® S-D5, willhelp prevent any problems.

“MOUTH ALCOHOL”

Twenty (20) minutes should pass between theconsumption of alcohol and a breath test using theIntoxilyzer® S-D5. This period allows for any “mouthalcohol” to be dispersed. “Mouth alcohol” will giveartificially high breath readings and is not indicative ofactual impairment of the subject.

MOUTHPIECE

Use a new mouthpiece for every subject breath test,calibration check and calibration adjustment. Insurethat the subject blows (or the alcohol standard isintroduced) through the lipped edge, wide-bored end.Only mouthpieces from CMI, Inc. should be used.

SMOKING

Smoking just prior to a breath test will not influencethe result, but tobacco smoke should not be blownthrough a mouthpiece attached to the instrument.Tobacco smoke could damage the fuel cell.

POINTS TOREMEMBER

19


MANUAL BREATH SAMPLING

When a sufficient volume of breath is blown into themouthpiece, the Intoxilyzer® S-D5 automatically “takes”a sample for analysis. If, for any reason, the subjectcannot or will not provide a sufficient sample, FunctionButton A can be pushed while the subject is blowing tomanually obtain a sample for analysis.

STORAGE BETWEEN TESTS

Avoid storing the Intoxilyzer® S-D5 in temperatureextremes.

BATTERY REPLACEMENT

The Intoxilyzer® S-D5 is powered by two AAA batterieswhich are under the battery cover on the backside ofthe unit. A low battery warning appears on the displaywhen battery power is low, and they should be replacedas soon as possible.
