checking to insure the fuel cell is discharged and free of

alcohol from any previous sample. Elimination of alcohol

from the fuel cell should take no longer than two

minutes—except in unusual cases—depending on how

much alcohol was actually present in the last sample.

To conduct a READY CHECK, depress the ‘READ’ button

and hold it down for at least ten seconds. This

will release the ‘SET’ button and switch on the amplifier

and display circuits. Observe the display; it should not

exceed .002 after ten seconds. If the display does not

show .002 or less during the ten second READY CHECK,

the fuel cell may have traces of residual alcohol from a

previous sample. If this occurs after a previous test,

depress the ‘SET’ button to lock and wait one minute

before repeating the READY CHECK. If the left digit

shows ‘L’, replace the battery.

2) SET

Once the READY CHECK is complete, the sampling

system must now be SET to prepare it to draw a breath

sample into the fuel cell for analysis. Press down the

‘SET’ button until it locks. This pushes down the

diaphragm and holds it against a spring-loaded catch.

This action also places a short-circuit across the fuel cell,

which accelerates its inter-sample recovery time.

To complete the READY

CHECK, depress the

‘READ’ button for at least

ten seconds.
