PAS VR. ‘DRY GAS’ CALIBRATION PROCEDURE
:
The calibration adjustment process assumes the following conditions:
*The instrument has not analyzed more than three samples containing alcohol within the
previous half-hour or any sample within the previous 5 minutes.
•
The instrument is in its normal operating temperature range, and
•
The battery does not need replacement.
EQUIPMENT CHECKLIST FOR DRY GAS CALIBRATION OR ACCURACY CHECK
:
1. Regulator: 1.5 LPM. A Trigger (see photos below) or Push Button type.
2. Ethanol Breath Dry Gas Standard
– 0.01%.*
3. Calibration Connector Tube
!) Preliminary
Inspect the instrument for damage and that the intake port is not blocked/plugged.
Select the appropriate “Calibration Connector Tube” for the Dry Gas procedure.
Dry Gas Standard: 0.01% (used for either PASSIVE or ACTIVE modality calibration)
2) Zero Check (Air Blank)
This insures the instrument is ready to take a sample of the dry gas standard and tests
whether the fuel cell is completely discharged and free of alcohol from a previous sample. It also
insures the battery has sufficient power to drive the electronic circuitry.
Switch the POWER on. Set mode switch to PASSIVE. Wait a minimum of 1-2 minutes for
initialization process to complete.
