Parameter Reference Guide

15.1.19 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 incorrect application of gas.
Parameter Name Default Setting Value Range
Maximum Zero Offset 5 mA
Minimum Zero Offset 3 mA
Maximum Span Signal 20.0 mA
Minimum Span Signal 5 mA
15.1.20 Calibration Span Gas Settings
Access Level: Engineer
Note: 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.
Parameter Name
Maximum Span Gas Conc
Minimum Span Gas Conc
Default Span Gas Conc
15.1.21 Inhibit Signalling Settings
Access Level: Engineer
Parameter Name Default Setting

Inhibit Level Min 2.0 mA
1 to 15 mA
1 to 8 mA
8.0 to 24.0 mA
0.0 to 12.0 mA
Default Setting Value Range
100 %FSD 80 to 100 %FSD (According to
sensor range)
30 %FSD 15 to 80 %FSD (According to
sensor range)
50 %FSD According to sensor range
Value Range
Enabled / Disabled
1.0 to 3.9 mA
0.8 to 3.8 mA
Comment
During calibration, the "Zero Signal Too High" warning is set if the
zero signal exceeds the Maximum Zero Offset
During calibration, the "Zero Signal Too Low" warning is set if the
zero signal is below the Minimum Zero Offset
During calibration, the "Calibration Signal Too High" warning will
be set if the span signal exceeds the Maximum Span Signal.
During calibration, the "Calibration Signal Too Low" warning will be
set if the span signal is below the Minimum Span Signal
Comment
Sets the Maximum Span Gas Concentration that
can be used during calibration. Must be greater
than the Minimum Span Gas Conc.
Sets the Minimum Span Gas Concentration that
can be used during calibration. Has to be less than
the Maximum Span Gas Conc.
Sets the Default Span Gas Concentration to be
used during calibration.
Comment
If enabled, a specific signal level from the sensor will activate an
inhibit condition for the channel.
The recommended minimum difference between Inhibit Level
Max and Inhibit Level Min is 0.2 mA
