DriftCal Enabled and Two
Gases Selected (cont.)
The Perform ZeroCal option:
This option performs a zero gas calibration of the XMO2 using the
zero gas and time interval specified in the Set Zero Gas option.
IMPORTANT: Be sure the XMO2 is connected to the correct zero
gas at the correct flow rate prior to using the
Perform ZeroCal option. Refer to Chapter 4, Field
Calibration, for details.
If
[Y] was pressed above, the XMO2 begins taking zero gas readings.
Approximately every 2.5 sec, it displays the % oxygen and the time
remaining for the calibration.
After the specified calibration time has expired, the XMO2 records
the calibration data and displays the new calibration.
Note: If the XMO2 does not reach equilibrium before the calibration
time expires, the calibration is rejected and the error message,
“Zero Gas Calibration Error-Check Cal Gases” is displayed.
To correct the error, erase the DriftCal data in the Reset
DriftCal menu (see page 6-33).
This completes the prompts for the Perform ZeroCal option, and the
XMO2 returns to the Two-Gas DriftCal menu.
