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 =XXX. 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 instru ment.
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 butto n now
appears d uring the
transition from zero to span.
You may see bot h button s.
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

STB test function.
This functi on calcu lates the
stability of t he H2S
measurement
Press ENTR to changes the
OFFSET & SLOPE values for the
H2S measur ements.
Press EXIT to leave the calibration
unchange d and return t o the
previous menu.
A
CTION:
Allow span gas to enter the sample port at the
rear of the instru ment.
The value of
H2S STB may jump
significantly.
Wait until it falls back
below 0.5 ppb.
This may take several
minutes.
Press ENT R to change the
OFFSET & SLOPE value s for the
H2S measur ements.
Press EXIT to leave the calibration
unchange d and return t o 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.
