ALCOSIM SETUP AND OPERATION
STEPS
1. With the ALCOSIM breath alcohol simulator power disconnected, turn the
top housing counter clockwise (left) and detach it from the container.
2. Add the entire contents of the 500 mL bottle of alcohol reference solution
into the ALCOSIM solution container.
The bottle contains the exact liquid volume required for calibration, which is
also marked on the ALCOSIM container.
3. Return the top housing onto the container, be careful not to over tighten.
4. Connect tubing with the round mouthpiece to the ALCOSIM simulator air
inlet and tubing with the liquid trap mouthpiece to the air outlet.
5. Perform a leak check by covering the air outlet tube with your thumb and
blowing into the air inlet tube.
Air bubbles should not appear in the solution. In case of bubbling, check
that the ALCOSIM head is tightened properly. Return the ALCOSIM to an
authorized Service Provider if the problem persists.
6. Connect the power cable to the simulator power input and to a wall outlet.
7. Switch on the simulator. The following occurs:
•
The LCD display illuminates and the simulator beeps
•
The propeller rotates and the heating element activates
•
Cold is displayed until solution reaches 32 ºC, wherein the LCD screen
displays actual solution temperature
•
The simulator maintains solution at a constant 34 ºC ± 0.02 ºC
Solution heat-up takes about 10 minutes. When 34 ºC ± 0.02 ºC is displayed,
the simulator is ready to provide a breath sample.
8. Use the ALCOSIM simulator to blow air into the breath alcohol tester that
you are calibrating. There are two ways of doing this:
•
Manually: take a deep breath and blow for the duration of the breath test
sample period
•
Mechanically: use a pump-powered air source (Recommended flow rate:
14.4 L/min)
