1) READY CHECK
This insures that 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 that the battery has sufficient power
to drive the electronic circuitry.
Press the ‘READ’ button and hold down for at least ten
seconds. This will release the ‘SET’ button and activate
the electronics. During these ten seconds, the display
should not read more than .002. A higher reading shows
that alcohol may still be present in the fuel cell. If this
occurs, depress the ‘SET’ button to lock, wait one minute
and repeat the ten-second READY CHECK.
If the letter ‘L’ is displayed, replace the unit’s battery.
2) SET
Assuming the READY CHECK has been completed,
depress the ‘SET’ button to lock. This prepares the
instrument to sample the dry gas standard.
3) SAMPLE THE DRY GAS STANDARD
Follow the procedure below to sample the standard:
a) Use a new mouthpiece and attach its
lipped end to the outlet on the regulator
button.
b) Insert the S-D2’s sampling port into the hole

c) Hold the instrument with your thumb

d) Depress the regulator button so that gas
