values for the O
2
measurement.
Press EXIT to leave the
calibration unchanged and

EXIT at this point
returns to the
SAMPLE menu.
Press ENTR to change

measurement.
Press EXIT to leave the

return to the previous
menu.
Allow zero gas to enter the sample port
at the rear of the analyzer.
Wait until O2 STB
falls below 0.01%.
This may take several
minutes.

Allow span gas to enter the sample port
at the rear of the analyzer.
Wait until O2 STB
falls below 0.01%
This may take several

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.
