DriftCal Enabled and One
Gas Selected
The Set Offset Gas option:
At the following prompt, specify the % oxygen of the offset gas to be
used for the DriftCal calibration (see the Calibration Sheet supplied
with your unit for recommendations).
Note:
Typically, the XMO2 is factory-programmed for one-gas
calibration using air (20.93% O
2
) as the offset gas.
At the Offset Gas prompt, enter the %O2 for the intended offset gas.
Note:
The gas type in the next prompt is set in the Select Gas Type
option of the Advanced Menu . The choices are %O2 (used as
an example in this manual), %H2 , %N2 , %SO2 , and %CO2 .
Refer to Chapter 7, Advanced Programming , for more details.
At the Offset Gas ON for prompt, set the time interval for which the
XMO2 waits before recording the new calibration point. GE Sensing
recommends a time of 0.00 and calibrating the unit after it has
reached equilibrium with the specified calibration gas.
At the Enter Calibration Span prompt, specify the high end of your
calibration range (see your Calibration Sheet for the span value).
This completes the prompts for the Set Offset Gas option, and the
XMO2 returns to the One-Gas DriftCal menu.
