Select either General or Zero diagnostic from the menu.
General will display values for the measurements in the sample, while Zero
is used to display values when the gas concentration is at zero (e.g. during
a zero calibration using pure nitrogen as the calibration medium).
The screen layouts are identical for both diagnostic options, and show
useful information for troubleshooting purposes.
The first screen displays measurement information, with a status (OK or
NOK) alongside. A status of NOK indicates the value is outside of the
acceptable minimum or maximum value. To view the acceptable range limits
press the Show criteria button.
The criteria screen displays the acceptable range limits (minimum and
maximum values) for more in-depth troubleshooting.
Note: If Zero diagnostic is selected, a warning message appears. Ensure
