INTRODUCTION

The Mercury is the latest in the C4 Technology line of affordable, professional, handheld quantitative breath alcohol testing instruments. It can be used for law enforcement, schools, workplace safety or medical purposes. The Mercury features an easy-to-use automatic sampling or manual sampling with a user-friendly touch-screen display and an optional wireless printer.

The Mercury is accurate and reliable, allowing a complete breath test procedure to be conducted in about 30 seconds or less.

This manual describes the operation, maintenance, calibration check, and calibration adjustment of the Mercury. This manual should be read completely and fully understood by each operator prior to testing. It is further recommended that operators practice the breath testing process before giving an actual “in the field” test.

NHTSA APPROVED

EVIDENTIAL BREATH ALCOHOL TESTING DEVICE (EBT)

1

PRINCIPLES OF OPERATION

The Mercury uses an electrochemical fuel cell containing two platinum electrodes to detect and measure the concentration of alcohol vapor in expired breath. When breath is drawn into the fuel cell by the sampling system, a small voltage is generated proportionate to the breath alcohol concentration. This voltage is then fed to an electronic amplifier and displayed on the screen.

The instrument is simple to operate and may be used as often as required provided that a suitable delay is allowed between successive tests. This time delay allows the fuel cell to clear itself of alcohol and prevents the possibility of additive readings. If no alcohol is present in a test, a second test may be analyzed immediately, since the fuel cell voltage is already at zero. Unless the breath alcohol level of the subject is very high, the instrument will generally be clear enough to receive and analyze a second sample in less than two minutes.

INSTRUMENT FEATURES

1. DISPOSABLE MOUTHPIECE: For sanitary reasons, each mouthpiece is individually packaged and sealed. A new mouthpiece should be used for each test.

2. SAMPLING CUP: A sampling cup is reusable. Attach to the sample port and do not allow subject to touch the sampling cup while providing a breath sample.

Remove and clean with a mild disinfectant (alcohol-free) for the next use.

3. LEVER TO REMOVE MOUTHPIECE: For sanitary reasons, the mouthpiece can be ejected by pushing up on the lever on the left side of the Mercury.

4. TOUCH SCREEN DISPLAY: A user-friendly touch-screen displays instructions and test results. Select the icons and buttons on the screen by using the attached stylus pen located on the top of the instrument behind the sample port.

5. EXTERNAL POWER CONNECTORS: The 12V wall adapter can be used to charge the printer battery. If rechargeable AA batteries are being used in the unit, these can be recharged using the 12V auto adapter.

6. USB CONNECTOR: A USB cable can be used to download stored test records from the Mercury onto a PC.

PERFORMING A BREATH TEST

Before performing a breath test, several conditions for the test site and the test subject must be verified

Conditions for Test Site

•

The ambient air should be free from alcohol, solvent vapors, and thick tobacco smoke.

•

Working temperature of the Mercury should be between 14°F to 122°F (-10ºC to

50ºC).

Note: Do not allow an unrealistically high ethanol concentration to reach the sensor, since this can reduce the life expectancy of the unit.

Conditions for Test Subject

•

The person being tested must abstain from drinking, eating, chewing gum, chewing tobacco, smoking tobacco, using mouth spray, or taking any medications for at least 15 minutes prior to providing a sample. (If a positive sample is given in workplace testing, a minimum 15 minute waiting period must occur after the initial screening test.)

•

The person being tested must breathe evenly and normally before the test. The person must also avoid repeated deep breaths (hyperventilation) as this will temporarily cool down the breath and may lead to a false reading.

•

Should the person have diminished lung capacity and cannot activate the Auto

Test, a manual override method is provided.

Note: Rinsing out the mouth with water or non-alcoholic drinks does not substitute for the 15 minute interval between a screening test and a confirmation test.

Attaching a Mouthpiece

•

Remove the disposable mouthpiece from its wrapper, making sure not to touch the end into which the subject will be blowing.

•

Snap the disposable mouthpiece onto the top of the Mercury to ensure a secure fit.

•

After use, the mouthpiece can be removed from the Mercury by using the lever on the left of the instrument. Slide this lever up to disengage the mouthpiece without needing to touch it.

5

Performing an Air Blank Test

The Mercury performs an Air Blank test to determine if ethanol is present in the ambient air or if any residual alcohol is remaining from prior testing. An Air Blank test should be performed if there is suspicion that the ambient air contains alcohol vapor, or prior test carryover is suspected, or before a confirmatory test. The Mercury automatically performs an air blank every time the Standard Test Icon is selected and before going into Test Mode.

If a reading greater than 0.000% is noted on the Air Blank Result, return to the Main

Menu, wait 2-3 minutes, then select the Standard Test Icon again and check the Air

Blank Result.

MEASURING BREATH ALCOHOL CONCENTRATION (BrAC/BAC)

Passive Test:

1. Attach a sampling cup onto the sample port.

2. When Mercury displays “Please Blow”, instruct subject to take a deep breath and blow towards the sampling cup until the beep tone changes.

3. “Alcohol Detected” or “No Alcohol” will display on the screen.

4. A manual override can be performed by selecting “Manual” while the subject is blowing.

5. Select to start another test.

6. If alcohol is detected, use a mouthpiece to perform a standard test to obtain an accurate reading.

7. The sampling cup should be cleaned with an alcohol-free mild disinfectant.

Screening Test results can be printed and/or stored in the test records of the device. You can elect to save Screening Test Results, by selecting the

“Screening Results Saved” option in the Advanced Settings.

NOTE: The Screening Test (Passive Test) is used only for screening purposes to determine if alcohol is on the breath sample. An accurate test can only be obtained by using a Standard Test.

6

Standard Test:

1. Attach a disposable mouthpiece onto the sample port.

2. Select the Standard Test Icon on the Main Menu.

3. Instrument will display Air Blank Processing as it checks for residual alcohol in the air or in the fuel cell.

5. Input information by a stylus pen, if this feature is active. (NOTE: 16 characters maximum for each input). Identifying fields, such as name, license number, etc can be chosen by the operator and are found under the

Advanced Settings.

6. Instrument will then automatically go into Test Mode and display the next

Test Record Number.

7. When Mercury displays “Please Blow”, have subject take a deep breath and blow until the beep tone changes. You will notice the Time (T) and Volume

(V) indicators count up from 0% to 100%.

8. Test Result displays on the screen.

9. If subject did not blow within 30 seconds, operator can select “Refuse” to confirm the subject refused to do the test. Or operator can select “Test

Again” to allow subject to do the test again.

10. If subject failed to give a valid breath sample, operator can select

“Discontinue” to confirm, or select “Test Again” to allow subject to test again.

The Mercury will also detect if the subject attempts to suck air back through the mouthpiece. In this case, the Mercury will display “Discontinue” or “Test

Again” instead of displaying a test result.

11. Upon completion of the test, push up on the lever on the left side of the

Mercury to remove the mouthpiece.

12. Select to print the test result, if optional wireless printer is available.

13. To take another test, attach a new mouthpiece and select . The instrument will perform another Air Blank before going back into Test Mode and displaying a new Test Record Number.

ACCURACY CHECKING AND CALIBRATION

Accuracy testing should be performed at least once per month to ensure that BAC readings are reliable. If the result of the accuracy test is not within the acceptable range, the unit must be re-calibrated by PAS Systems International, Inc. or by persons who have been properly trained for alcohol detector calibration.

Due to the sensitive nature of BAC testing, it is extremely important to keep detailed records of both accuracy tests and recalibrations for each Mercury unit. Procedures for recording this information are covered in BAT training and documentation when provided.

PAS recommends all Mercury units be calibrated annually or whenever an accuracy test shows that BAC readings are no longer within tolerance limits. Because precise calibration is crucial, it can be performed only by PAS Systems International or by persons who have been properly trained for alcohol detector calibration. (Calibration of the Mercury must be performed using a NHTSA-approved wet bath simulator or certified dry gas standard.) Successful completion of calibration should be recorded in a calibration log. Please refer to the Quality Assurance Plan (QAP) documentation in the next section for additional calibration requirements.

WET BATH ACCURACY CHECKING

Using wet bath simulators for accuracy checking has been the accepted method for many years. Breath alcohol simulators are specially designed water-alcohol instruments which provide equilibration of alcohol between water and air at a controlled temperature.

Accuracy checking of the Mercury should be performed by authorized persons using any NHTSA approved breath alcohol simulator.

To perform a wet bath accuracy check:

1. Pour 500 ml of 0.080% Certified Solution into the glass jar.

2. Attach a piece of tubing (6 - 8” long) to simulator inlet. Attach a regular or checkvalve mouthpiece to the end of this tubing.

3. Attach a 1 - 2” piece of tubing to the simulator outlet. Attach a mouthpiece to the other end of this shorter tubing. Make sure the connection is air-tight.

Note: The length of tubing connected to the simulator outlet should not be longer than 2” in order to prevent condensation.

4. Plug Simulator in and turn switch to the ON position.

12

5. Allow the solution to heat.

6. After 15 - 20 minutes, check the thermometer. The thermometer should read

34ºC when ready.

7. Attach instrument to the mouthpiece. (The opaque moisture trap can be used should condensation appear in the mouthpiece).

8. Switch on the Mercury. Choose the icon to perform a Standard Test and wait for instrument to perform the Air Blank test.

9. Forcefully blow into the simulator for several seconds and then press the “Maual” button on the screen.

After a few seconds, the measured value will be displayed. The display should read

0.08% +/-0.005.

NOTE: If the result is not within published specifications for the Mercury, conduct another accuracy check. Verify that the seal on the simulator is air-tight and that the outlet tube and mouthpiece are free of condensation. If the measurement is still not within specifications (+/- 0.005), the unit must be removed from service until an internal calibration can be conducted.

DRY GAS ACCURACY CHECKING

When using dry gas for accuracy testing (PAS recommends 0.080% dry gas concentration), the alcohol concentration printed on the label of the gas cylinder must be corrected to account for altitude when conducting tests at or above an altitude of 250 feet above sea-level. Please refer to the “Dry Gas at High Altitude” section below for instructions on how to make the appropriate corrections for high altitude testing.

To perform the accuracy test:

1. Attach a new mouthpiece.

2. Turn on the Mercury. Select the Standard Test icon and wait for instrument to perform the Air Blank Test. Always pre-purge the valve for a few seconds before delivering a sample for testing.

3. Connect the Mercury to the regulator/valve of the gas cylinder (the regulator must provide a gas flow of at least 1.5 liters per minute).

4. Depress the regulator button and allow gas to flow for 8 seconds. While the gas is still flowing, p ress the “Manual” button on the screen (manual test).

13

5. After a few seconds, the measured value will be displayed. If the measured value is within +/-0.005 BrAC of the altitude-adjusted concentration value, the Mercury is working accurately.

Note: Suitable Dry Gas Standards and Regulators are available from PAS Systems

International, Inc. (800-660-7643)

Dry Gas at High Altitude:

The Concentration of alcohol in a dry gas standard is carefully controlled to give the correct vapor concentration when the cylinder is at sea level. At higher elevations

(altitudes), the concentration of the alcohol in the vapor leaving the cylinder will be less.

This change in concentration at sea level is negligible, but at higher altitudes significant errors would result if corrections were not made. Simply multiply the standard concentration on the gas cylinder label by the factor shown for the appropriate local altitude listing in the High Altitude Correction Chart.

For example, if you have a dry gas standard of 0.045% and you are using it at 500 feet, you would multiply the value at sea level by the correction factor. The corrected value would be 0.045 x 0.981 = 0.044%
