9.3.18 Calibration Signal Settings
Access Level: Engineer
Note: These settings refer to the range of signal values from the sensor over which calibration will be permitted, and are
used to avoid incorrect calibration e.g. due to a decaying sensor or incorrect application of gas.

100 to 300 mV
Maximum allowable signal at 100% FSD for new beads.
Note: This is scaled by the span gas concentration
entered in the Span Gas Concentration field
Minimum Span
Signal
0 mV
-50 to 100 mV
Minimum allowable signal at 100% FSD for aged beads.
Note: This is scaled by the span gas concentration
entered in the Span Gas Concentration field
9.3.19 Calibration Span Gas Settings
Access Level: Engineer
These settings refer to the range of gas concentration values that can be used for span calibration, and are used to ensure
that the sensor is calibrated at an appropriate level.
The Maximum Span Gas Concentration and Minimum Span Gas Concentration are the maximum and minimum values
that can be entered into the Span Gas Concentration field during calibration.
The Default Span Gas Concentration is the value initially displayed in the Span Gas Concentration field. This may be
changed by the user during calibration to match the actual gas concentration used.
