EXIT returns to the main
SAMPLE display
ACTION:
Allow zero gas to enter the sample port at the
rear of the instrument.

Wait until H2S STB
falls below 0.5 ppb.
This may take several
minutes.
The SPAN key now appears
during the transition from
zero to span.
You may see both keys.

SETUP
Set the Display to show the H2S
STB test function.
This function calculates the
stability of the H
2
S
measurement
Press ENTR to changes the
OFFSET & SLOPE values for the
SO
2
measurements.
Press EXIT to leave the calibration
unchanged and return to the
previous menu.
ACTION:
Allow span gas to enter the sample port at the
rear of the instrument.
The value of
H2S STB may jump
significantly.
Wait until it falls back
below 0.5 ppb.
This may take several
minutes.
Press ENTR to change the
OFFSET & SLOPE values for the
H
2
S measurements.
Press EXIT to leave the calibration
unchanged and return to the
previous menu.
NOTE
If the ZERO or SPAN keys are not displayed during zero or span calibration, the
measured concentration value is too different from the expected value and the analyzer
does not allow to zero or span the instrument.
Consult Section 11.3 for more information on calibration problems.
