STEP THREE: Perform the zero/span calibration:
M-P CAL SO2 STB=X.XXX PPB SO2 =XXX.X
< TST TST > ENTR CONC EXIT
M-P CAL SO2 STB=X.XXX PPB SO2 =XXX.X
< TST TST > CAL SETUP
M-P CAL SO2 STB=X.XXX PPB SO2 =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 instrument.
M-P CAL SO2 STB=X.XXX PPB SO2 =XXX.X
< TST TST > SPAN CONC EXIT
M-P CAL RANGE = 500.0 PPB SO2 =XXX.X
< TST TST > ENTR SPAN CONC EXIT
Wait until SO2 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.
SAMPLE RANGE = 500.0 PPB SO2 =XXX.X
< TST TST > CAL SETUP
Set the Display to show the
SO2 STB test function.
This function calculates the
stability of the SO
2
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.
A
CTION:
Allow span gas to enter the sample port at the
rear of the instrument.
The value of
SO2 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
SO
2
measurements.
Press EXIT to leave the calibration
unchanged and return to the
previous menu.
SAMPLE RANGE = 500.0 PPB SO2 =XXX.X
< TST TST > CAL SETUP
M-P CAL RANGE = 500.0 PPB SO2 =XXX.X
< TST TST > ENTR CONC EXIT

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 zeroing or spanning the
instrument.
Refer to Section 12.4 for more information on calibration problems.
