  4. Appendix 2A • Turn power button on or observe the power button has been activated. If the EBAT deviceis in the STANDBY mode, press the START TESTbutton. Rev. 3.09

  5. Appendix 2A 2. The subject must remove foreign objects fromthe nose and mouth including dentures. Thesubject must be closely and continuouslyobserved for 20 minutes prior to testing to assure no belching, regurgitation or intake of any foreignmaterial by nose or mouth has occurred. If suchoccurs, another 20 minutes of close andcontinuous observation must elapse under thesame conditions.Start Time: Stop Time: Rev. 3.09

  6. Appendix 2A 3. Verify that the external breath tube andsimulator vapor tube are both warm. SimulatorVaporTube ExternalBreath Tube Rev. 3.09

  7. Appendix 2A 4. Observe the simulator temperature is between33.8 degrees Centigrade and 34.2 degreesCentigrade. Simulator Display Rev. 3.09

  8. Appendix 2A 5. Press the START TEST button. Rev. 3.09

  9. Appendix 2A 6. Follow the instructions and sequence of events as they appear on the EBAT device display. Rev. 3.09

  10. Appendix 2A 7. Retain all printouts generated by the EBAT devicewith the DUI packet. (i.e. Error messageprintouts) Rev. 3.09

  11. Function Keys F1: EBAT Printout  Prints the last EBAT test record. Active when the Intoxilyzer 5000EN is in the Ready Mode and the printer buffer still contains the results of the last EBAT performed. Note: Evidential Breath Alcohol Test (EBAT) Rev. 3.09

  12. Function Keys F2: Print Simulator Log  Prints the current simulator log.  Active when the Intoxilyzer 5000EN is in the Ready Mode.  When depressed, it clears the printer buffer. The F1 key will no longer print the last EBAT due to the printer buffer being cleared. Rev. 3.09

  13. Function Keys F5: Data Entry Return Key  Returns the Intoxilyzer 5000EN to the Ready Mode when in a data entry operation.  Is active only when in a data entry mode. Rev. 3.09

  14. Function Keys F6: Subject Non-Compliance Key Aborts the Test Sequence. • Is active only from the end of the 2nd Air Blank until the end of the 2nd Breath Sample. Used only when the subject belches, regurgitates, or intakes a foreign material into their nose or mouth before the successful completion of the second breath test. Not to be used as a Refusal! Rev. 3.09

  15. Stand By Mode The purpose the Stand By mode is to extend thelife of critical electronic components in the Intoxilyzer5000EN. The power to the heater tapes is reduced during the Stand By mode. This allows the Sample Chamber, ExternalBreath Tube, Internal Breath Tube, and Heated SimulatorTube to warm up quickly to their proper operating temperatures within ten minutes when the Start/Test Switch is depressed. The Stand By mode is automatically entered whenever the instrument is in-active for 120 minutes. Rev. 3.09

  16. Stand By Mode Three indications that the instrument is in the Stand By Mode are: • The Intoxilyzer 5000EN display is blank. • The red LED below the Power On button is lit. • The Guth 2100 Simulator displays ‘IDLE’. Rev. 3.09

  17. Stand By Mode To bring the Intoxilyzer 5000EN out of the Stand By modeand into the Ready mode, depress the Start/Test Switch. The instrument will display the following message: And perform a short air purge NOT READY Rev. 3.09

  18. Stand By Mode The instrument will now display: WARM UP PERIOD XX:XX MST/MDT Current Time DATE XX/XX/XXXX Current Date Message repeats Rev. 3.09

  19. Stand By Mode The ‘WARMUP’ period allows the Intoxilyzer 5000EN and Guth 2100 Simulator to warm up to their proper operating temperatures. After the Warm Up period, the instrument will perform selfdiagnostic tests. These tests will ensure the Intoxilyzer 5000EN is ready to accurately perform Evidential Breath Alcohol tests.Once all these tests have passed, the instrument will enterthe Ready mode. Rev. 3.09

  20. Diagnostic Tests During the diagnostic tests, numerous checks areperformed to verify the proper operator of theIntoxilyzer 5000EN. Some of these tests are: Checks the temperature of the Sample Chamber toensure it is between 45C and 54C.If this test fails, the instrument will pause theDiagnostic Tests and display the current temperatureof the Sample Chamber. Once the temperatureis correct, the Diagnostic Tests will continue. TEMP CHECK Rev. 3.09

  21. Diagnostic Tests Tests the interface between the instrument and printer.Printer error information is displayed if detected. This error information will be displayed until the erroris corrected (i.e. Printer offline, Out of Paper). PRINTER CHECK DIAGNOSTIC OK Indicates all tests have passed. Rev. 3.09

  22.

Rev. 3.09

  23. Data Entry Rev. 3.09

  24. Test Sequence The test sequence of the Intoxilyzer 5000EN is comprisedof a series of steps or functions that ensure that when aerror free print out is obtained the result reported isreliable and accurate.This is accomplished by performing numerous internaltests checking the operation of the Intoxilyzer. If theinstrument detects an operation or result that is improper,it will generate the appropriate error message and abortthe test sequence. Rev. 3.09

  25. Test Sequence There are five functions that are performed during thetest sequence. Each function executes specific operationsas follows: A – Air Blank C – Calibration Check B – Breath Test I – Internal Standard Test 2 – Two minute wait period. Most of these functions are performs two or more timesduring the sequence. Rev. 3.09

  26. Test Sequence Air Blank There are seven Air Blanks performed during the testsequence. The primary purpose is to circulate room airthrough the sample chamber to remove any contaminatesthat may be present. This guarantees the sample chamberis clean prior to a Calibration Check, Breath Test, orInternal Standard Test. Rev. 3.09

  27. Test Sequence 1st Air Blank (continued). During an Air Blank, the instrument will display thefollowing: AIR BLANK XX:XX MST/MDT DATE XX/XX/XXXX AIR BLANK Rev. 3.09

  28. Test Sequence 1st Air Blank (continued). Once complete, the instrument will display the resultof the Air Blank. AIR BLANK .000 Rev. 3.09

  29. Test Sequence CAL Check There are two calibration checks (CAL Check) performedduring the test sequence. The primary function is to ensurethe instrument is within calibration limits (± 10%). This is accomplished by re-circulating the vapor from theGuth 2100 Simulator through the sample chamber and backto the simulator.The re-circulation allows the utilization of the standardsimulator solution for up to 96 subject tests. Rev. 3.09

  30. Test Sequence CAL Check During a CAL Check, the instrument will display: . . . . . . . CAL. CHECK CAL. CHECK .### At the completion of the second CAL Check, the instrumentwill compare the results of the two CAL Checks to ensurethey are within 10% of each other. Rev. 3.09

  31. Test Sequence Breath Test The primary function of a Breath Test is to accurately determine the BrAC of the subject. This is accomplished by the Beer-Lambert law. ‘Absorption is directly proportional to concentration.’ The following basic formula is used for this calculation: X – Y = Alcohol Concentration (BrAC) Were: X = Previsious Air Blank value (IR Concentration). Y = Current sample chamber value (IR Concentration). Rev. 3.09

  32. Test Sequence Breath Test (continued) The instrument will display the following at the start of abreath test. . . . . . . . PLEASE BLOW/R INTO MOUTHPIECEUNTIL TONE STOPS PLEASE BLOW/R Rev. 3.09

  33. Test Sequence Breath Test (continued) When the instrument displays ‘Please Blow/R’, the subjecthas approximately three minutes to provide a valid breath sample. If the subject does not provide a valid breathsample, a ‘Deficient Sample’ error message will be generated and the test sequence will be aborted.As long as the instrument displays ‘Please Blow/R’, theoperator can initiate a ‘Refusal’ if the subject refuses tofollow their instructions (“R” + <ENTER> on keyboard). Once the subject starts blowing, the instrument will display‘Please Blow’ and the refusal option can no longer be performed. Rev. 3.09

  34. Test Sequence Breath Test (continued) Valid Breath Sample: There are four requirements for a successful breath sample. They are: 1. Flow Rate 2. Time 3. Volume 4. Slope Rev. 3.09

  35. Test Sequence Breath Test (continued) Valid Breath Sample • Flow Rate: The subject must blow into the mouth piece at a rate of ≥ .15L / second. This minimum flow rate must be maintained until all four requirements are met. 2. Time: The subject must blow, at an acceptable rate, for a minimum of 1 second. Rev. 3.09

  36. Test Sequence Breath Test (continued) Valid Breath Sample • Volume: The subject must provide, at an acceptable rate, a minimum of 1.1 Liters of breath sample. 4. Slope: Once the first three requirement are met, the Intoxilyzer will determine a level slope of the breath sample within the sample chamber. A level slope is when the BrAC inside the sample chamber no longer increases by more than 3.2% per second or deceases by more than 1.6% per second. Rev. 3.09

  37. Test Sequence Typical Breath Sample: Slope levels out at approximately 4 seconds Rising Slope during the first 4 seconds and the first three requirements are met. Subject Stops Blowing BrAC Level Slope Detected 3 4 8 1 5 6 9 10 0 2 7 Rev. 3.09 Seconds

  38. Test Sequence Mouth Alcohol: Positive Slope during the first 3 seconds. The first 3 requirements are met. Slope peaks at approximately 3 seconds and should level out. Slope then start to continually drop from the peak at a rate of ≥ 5%. BrAC 0 1 2 3 4 5 6 7 8 9 10 TIME Rev. 3.09

  39. Test Sequence Breath Test (continued) Instrument checks for interferent conditions.( Acetone, Toluene, and other common alcohol.) NOTE: If an interferent condition is detected, the instrument will display INTERF DETECTED. After a few seconds, if the instrument displays SUBTRACTED, it indicates to the operator that the interferent was Acetone. Acetone has similar effects on the human brain as does Ethanol. A diabetic with an improper blood sugar level can naturally produce Acetone in their body, and in some cases exhibit the same mannerism as an individual who is intoxicated. The subject needs immediate medical assistance! Rev. 3.09

  40. Test Sequence Breath Test (continued) SUBJECT TEST . - - - The instrument will not display the results of thebreath test. This helps in ensuring the subject will providea second valid breath sample later in the testsequence. Rev. 3.09

  41. Test Sequence Breath Test (continued) PLEASE REMOVE SPIT TRAP ANDDEPRESS START TEST SWITCH Scrolling REMOVE SPIT TRAP Flashing Operator must comply with the above instrument message within approximately 1 minute and 10 seconds. If not, a ‘Step Expired’ error message will occur and the test will be aborted. Rev. 3.09

  42. Test Sequence Breath Test (continued) At the completion of the 2nd Breath Test, the two will becompared to ensure they are within 0.02 of each other. If they are outside this limit, a ‘NO 02’ agreement error will be generated. Rev. 3.09

  43. Test Sequence Internal Standard Test INTERNAL STD • This is a check of the instrument’s calibration and linearity using internal electronics values that equate to BrAC values of 0.100, 0.200, and 0.300. The results of all three Internal Standards must be within +/- 5% of the target values. • The addition of this step brackets the subject’s 1st and 2nd breath test with an instrument calibration and linearity check. • Will reduce challenges to the breath test accuracy by demonstrating the instrument was working properly after and before the subject provided the two breath samples. • Same Internal Standards test that is performed during the Diagnostic Checks. INTERNAL PASS Rev. 3.09
