Allow zero gas to enter the sample port at the
rear of the instrument.

Wait until STABIL
falls below1.0 ppm.
This may take several
minutes.
The SPAN button now
appears during the
transition from zero to
span.
If either the ZERO or
SPAN buttons fail to
appear see Section 11
for troubleshooting tips.

Set the Display to show the
STABIL test function.
This function calculates the
stability of the CO
x
measurement
Press ENTR to changes the
OFFSET & SLOPE values for the
CO

measurements.
Press EXIT to leave the calibration
unchanged and return to the
previous menu.
A
CTION:
Allow span gas to enter the sample port at the
rear of the instrument.
The value of
STABIL may jump
significantly.
Wait until it falls back
below 1.0 ppm.
This may take several
minutes.
Press ENTR to change the
