4) 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 on the mouthpiece.
c) Hold the instrument with your thumb
near the ‘READ’ button.
d) Depress the regulator button so that gas
begins flowing through the mouthpiece.
e) After about five seconds of continuous gas
flow, AND WHILE GAS IS STILL
FLOWING, press the ‘READ’ button
which draws a sample of gas into the unit.
Continue to hold down the ‘READ’ button.
f) When the sample has been taken, release
the regulator button to stop the gas flow.
IT IS ESSENTIAL THAT THE GAS IS STILL
FLOWING WHEN THE ‘READ’ BUTTON IS
PUSHED.
Sample the dry gas standard.
