You are then prompted to apply the O
2
zero gas to the calibration inlet port of
the sensor:
Inject Zero Gas
ENTER to Continue
CANCEL to Abort
6. Press the Enter key once you have applied this cal gas.
The zero gas display then appears:
D O2 xx.xx Set xx.xx
W O2 xx.xx Set xx.xx
Press ENTER to Zero
7. Press the Enter key once the zero gas reading on the left of the display has sta-
bilized. The reading on the far right of the first display line shows the setpoint
value you entered for the O
2
zero gas using the Cal Gas Values menu option.
This O
2
zero gas setpoint value should match the cal gas cylinder for the O
2
zero gas.
Then, if you specified a recovery time, the system will display the recovery
time remaining:
Recovery xx:xx
System Calibrating
The system then returns to monitoring process readings.
Be sure to reinsert the 1/4” tube cap on the calibration inlet port on
the sensor once you have completed the manual calibration. This
prevents air from getting into the sample gas line during normal
operations.
