The input is averaged over the time set.
Sets a tolerance level (in % of engineering range) to allow for deviation of the input signal
above or below the engineering range before an input failure is detected.
The Zero Adjustment and Span Adjustment parameters enable fine tuning of the inputs to
eliminate system errors. Apply a known input value and adjust until the required input value
is displayed.
Normally, Zero Adjustment is used with input values close to Eng Low (adjustment is
performed by applying an offset to the reading) and Span Adjustment is used with values
close to Eng High (adjustment is performed by applying a multiplier to the reading).
The analog outputs can be configured to retransmit any analog value and have a
configurable range from 0 to 24 mA. Output 1 can also be configured to function as a digital
output.
Note. Analog Output 2 is available only if an option board is fitted – see pages 15 (CM10),
16 (CM30) and 17 (CM50).
Selects the analog or digital output (applicable only to Analog Output 1).
Selects the parameter to be assigned to the output – see Appendix A, page 116 for
description of sources.
