    INTRODUCTION The MARK V is an affordable, handheld quantitative breath alcohol testing instruments. The Mark V is a NHTSA certified EBT. It can be used for law enforcement, schools, workplace safety, or medical purposes. The MARK V features easy-to-use automatic sampling or manual sampling procedures.
  • Page 6: Principles Of Operation

    PRINCIPLES OF OPERATION The MARK V 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.
  • Page 7: Preparing The Mark V

    The MARK V Alcovisor® Operation This section details the preparation required to use the MARK V, and the steps for performing a breath test. Preparing the MARK V Before using the MARK V, the batteries (AAA) must be installed and the unit turned on.

  • Page 9: Performing A Breath Test

    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.
  • Page 10: Measuring Brac/Bac

    Measuring Breath Alcohol Concentration (BrAC/BAC) Automatic Sampling 1. Insert a new disposable mouthpiece into the mouthpiece opening. The mouthpiece can be inserted from either side of the device. 2. Turn on the MARK V. 3. Instrument will display “AirCheck Processing” as it checks for residual alcohol in the air or in the fuel cell.
  • Page 11: Manual Sampling

    Manual Sampling This method can be used when the test subject has a diminished lung capacity and cannot activate the Automatic Sampling test. 1. Follow steps 1-5 under Automatic Sampling. 2. Instruct the person being tested to breathe in deeply and blow evenly into the mouthpiece without a break for a minimum of 4 seconds.
  • Page 12: Accessing Test Records

    Accuracy checking 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.
  • Page 13: Wet Bath Accuracy Checking

    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 MARK V should be performed by authorized persons using any NHTSA approved breath alcohol simulator.
  • Page 14: Dry Gas Accuracy Checking

    Dry Gas Accuracy Testing When using certified dry gas (PAS recommends 0.080% dry gas concentration) for accuracy testing, 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.
