STEP THREE: Perform the Zero/Span Calibration Procedure:
SAMPLE
< TST TST >
M-P CAL
< TST TST >
M-P CAL
< TST TST >
M-P CAL
< TST TST >
M-P CAL
< TST TST >
M-P CAL
< TST TST > ENTR
If the ZERO or SPAN keys are not displayed, this means that the measurement
made during that part of the procedure is too far out of the allowable range to do
allow a reliable calibration. The reason for this must be determined before the
analyzer can be calibrated. See Section 11 for troubleshooting tips.

CALIBRATION PROCEDURES
WAIT 10
MINUTES
Or until the
reading
stabilizes and
the ZERO button
is displayed
This operation changes the calculation
equations and zeroes the instrument
WARNING!
If you are performing a ZERO CHECK
DO NOT press ENTR
If performing a CHECK, press EXIT now.
WAIT 10
MINUTES
Or until the
reading
stabilizes and
the SPAN button
is displayed
This operation changes the calculation
equations and sets the Span of the instrument
NOTE:
In certain instances where low Span gas
concentrations are present (? 10 ppm),
both the Zero & SPAN buttons may appear
simultaneously
WARNING!
If you are performing a Span CAL CHECK DO
NOT press ENTR
If performing a CHECK, press EXIT now.
If either the ZERO or
SPAN buttons fail to
appear see Section 9 for
troubleshooting tips.
