CALIBRATION PROCEDURE

This calibration procedure requires that the ALCOSCAN tester be in ADMIN Mode.

Refer to the "Entering ADMIN Mode" section of this manual for more information.

NOTE: Ensure that the unit is within the ambient temperature range of 20 to 30 °C.

Position the ALCOSCAN tester 10 cm away from the diffuser and ensure that

drafts of air (e.g. from air conditioners, fans, etc.) cannot interfere with the sample.

Blow moderately and continuously into the round mouthpiece. After 5 seconds,

while still blowing, press the power button on the ALCOSCAN tester.

The tester will vibrate as it collects the breath sample. Stop blowing when the

vibration ends.

The Status LED will blink amber while it analyzes the sample. If the alcohol

detected is not the expected concentration, the Status LED will blink red and the

blue/red Result LEDs will blink.

NOTE: When an error at any stage has occurred the procedure will restart from step 1.

NOTE: An otherwise flawless procedure can be impacted by environmental conditions,

improper distance from the diffuser, sensor age and use, etc.

When the WARN LED turns back to blue, repeat the sampling process (steps 2

to 4).

The Status LED will blink green to indicate that the ALCOSCAN tester was

calibrated successfully and the green result LED will blink for 3 seconds. The

success of the final sample ensures that the final reading is within the range of

the required ± 5 mg%.
