STEP THREE: Perform the zero/span calibration:
M-P CAL H2S STB=X.XXX PPB H2S =XXX.
X
< TST TST > ENTR CONC EXIT
M-P CAL H2S STB=X.XXX PPB H2S =XXX.X
< TST TST > CAL SETUP
M-P CAL H2S STB=X.XXX PPB H2S =X XX.X
< TST TST > ZERO CONC EXIT
EXIT returns to the main
SAMPLE display
A
CTION:
Allow zero gas to enter the sample port at the
rear of the instrument.
M-P CAL H2S STB=X.XXX PPB H2S =XXX.X
< TST TST > SPAN CONC EXIT
M-P CAL RANGE = 500.0 PPB H2S =XXX .X
< TST TST > ENTR SPAN CONC EXIT
M-P CAL RANGE = 500.0 PPB H2S =XXX.X
< TST TST > ENTR CONC EXIT
Wait until H2S STB
falls below 0.5 ppb.
This may take several
minutes.
The SPAN button now
appears during the
transition from zero to span.
You may see both buttons.
SAMPLE RANGE = 500.0 PPB H2S =XXX.X
< TST TST > CAL SETUP
SAMPLE RANGE = 500.0 PPB H2S =XXX.X
< TST TST > CAL SETUP
Set the Display to show the H
2
S
STB test function.
This function calculates the
stability of the H
2
S
measurement
Press ENTR to changes the
OFFSET & SLOPE values for the
H
2
S 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
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 buttons 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 zeroing or spanning the instrument.
Consult Section 9.3 for more information on calibration problems.
