Zero/Span Calibration
To perform the zero/span calibration procedure, press:
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.
SAMPLE STABIL= XXXX PPB SO2=XXX.X
< TST TST > CAL SETUP
M-P CAL STABIL= XXXX PPB SO2=XXX.X
<TST TST> ZERO CONC EXIT
EXIT at this point
returns to the
SAMPLE menu.
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.
SAMPLE RANGE=500.0 PPB SO2= XXXX
< TST TST > CAL SETUP
Set the Display to show
the STABIL test function.
This function calculates
the stability of the SO
2
measurement.
Toggle TST> button until ...
Allow zero gas to enter the sample port
at the rear of the analyzer.
Wait until STABIL
falls below 0.5 ppb.
This may take several
minutes.

< TST TST > CAL SETUP
M-P CAL STABIL= XXXX PPB SO2=XXX.X

M-P CAL STABIL= XXXX PPB SO2=XXX.X
<TST TST> ZERO SPAN CONC EXIT
Allow span gas to enter the sample port
at the rear of the analyzer.
Wait until STABIL
falls below 0.5 ppb.
This may take several
minutes.
SAMPLE STABIL= XXXX PPB SO2=XXX.X
< TST TST > CAL SETUP

The SPAN button now
appears during the transition
from zero to span.
You may see both buttons.
If either the ZERO or SPAN
buttons fail to appear see the
Troubleshooting section for
tips.
