DOS AND DON’TS
In cold weather, turn on the flashlight (and fuel cell heater) before using the PAS
V Sensor. This reduces the response time.
Hold the unit with the inlet port 5-7 inches from the subject's mouth.
Keep the subject speaking when sampling.
Keep your fingers away from the inlet and outlet ports.
Turn off the PAS when not in use.
Treat your PAS V with the respect deserved by any precision instrument. Protect
it from temperature extremes (don't leave it on your dash in the midday sun).
Remove the battery pack if the unit is not going to be used for more than a
month.
Use only the rechargeable battery pack obtained from PAS Systems
International. These are industrial grade batteries with much higher capacity and
longer life than the consumer grade equivalents.
Have the calibration of your unit checked once a year, or whenever it seems to
be losing sensitivity.
Take strong samples from right over an alcoholic beverage. The fuel cell takes a
long time to recover, and frequent overloads will damage it.
Sample raw cigarette smoke. This rapidly damages the fuel cell.
Allow liquids to enter the inlet or outlet ports.
Allow the metal case of the flashlight to come into contact with metal parts of the
vehicle when charging.
Use the PAS V where it is exposed to high winds that can blow the breath
sample away from the inlet port. At the side of a busy road, subjects should be
checked in their vehicles whenever possible.
Subject the PAS V to abuse such as excessive shocks.
Attempt to dismantle the unit. This will void the warranty.
Clean the unit or case with chemical solvents. You might damage the fuel cell
permanently.
