15.2.16 Calibration Reminder Settings

Access Level: Engineer
Note: Once the Calibration Overdue Warning is active, it can only be cleared by calibrating the channel.
Parameter Name
Calibration Reminder Enable
Calibration Reminder Interval
15.2.17 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.
Parameter Name Default Setting
Maximum Zero Offset 100 mV
Minimum Zero Offset -90 mV
Maximum Span Signal 100 mV
Minimum Span Signal 0 mV
15.2.18 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 100 %FSD
Minimum Span Gas Conc 30 %FSD
Default Span Gas Conc
Default Setting Value Range
Disabled Enabled / Disabled
6 months 1 to 24 months
Value Range
0 mV to 200 mV
-90 mV to 0 mV
100 to 300 mV
-50 to 100 mV
Default Setting Value Range
80 to 100 %FSD
(According to
sensor range)
15 to 80 %FSD
(According to
sensor range)
50 %FSD According to sensor
range
Comment
'Calibration Overdue Warning' is set if the 'Calibration
Reminder Interval' is exceeded.
Calibration reminder is calculated to the day, e.g. if the
reminder is set on 27 January for 6 months time, the
calibration overdue reminder will appear on 27 July.
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. Must be less than the Maximum Span Gas
Conc.
Sets the Default Span Gas Concentration to be used during
calibration.
