If you selected Introduce Gases and [Y]:
If you selected Introduce Gases at the Calibrate Mode prompt and
[Y]
at the Enter Point? prompt, you may begin calibrating the XMO2 at
the current %O2/%N2/pressure point by introducing a gas with the
appropriate pressure and oxygen/background gas composition.
The XMO2 displays working... as it records the calibration data, and
then returns you to the Enter Point? prompt on page 6-20.
If you selected Introduce Gases and [N]:
If you selected Introduce Gases at the Calibrate Mode prompt and
[N]
at the Enter Point? prompt, the Interpolate Point? prompt is used to
have the XMO2 perform a linear interpolation to determine the
corresponding mV value for the current %O2/%N2/pressure point.
Note: The XMO2 linear interpolation capability is useful when you
do not have a calibration gas with the required pressure and
oxygen/background gas composition for a given point.
The XMO2 displays working... as it records the calibration data, and
then returns you to the Enter Point? prompt on page 6-20.

Initiate the calibration gas flow,
then press
[Y] or [Enter].
Press [YES] when ready.
Press [YES] when settled.
When the displayed mV and
pressure values stabilize, press
[Y] or [Enter].
