9.7.2.4. CO2 ZERO/SPAN CALIBRATION
To perform the zero/span calibration procedure:
Press ENTR to change
the OFFSET & SLOPE
values for the O
2
measurement.
Press EXIT to leave the
calibration unchanged and
return to the previous
menu.

SAMPLE CO2 STB=X.XX % O=XX.XX
< TST TST > CAL SETUP
M-P CAL CO2 STB=X.XX % O=XX.XX
<TST TST> ZERO CONC EXIT
EXIT at this point
returns to the
SAMPLE menu.
Press ENTR to changes
the OFFSET & SLOPE
values for the CO
2
measurement.
Press EXIT to leave the
calibration unchanged and
return to the previous
menu.
Allow zero gas to enter the sample port
at the rear of the analyzer.
Wait until CO2 STB
falls below 0.01%.
This may take several
minutes.

<TST TST> ZERO SPAN CONC EXIT
Allow span gas to enter the sample port
at the rear of the analyzer.
Wait until CO2 STB
falls below 0.01%
This may take several
minutes.

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
chapter on Troubleshooting
for tips.
