Set the Mains rejection frequency used to filter electrical
noise induced on the signal lines by power supply cables.
Note. If the Mains rejection frequency is changed, the
instrument must be powered down and powered up again in
order to restore the inputs.
Input Adjustment
Inputs can be fine-tuned to remove process offset errors or
system scale errors.
Notes.
• Input Adjustment frames appear only if recording is
enabled during configuration – i.e. 'Disable recording in
configuration' is not selected on entry to the Configuration
level – see Fig. 4.2.
• Changes to the Analog Input Type (Section 4.6.2) must be
saved to the current configuration before commencing
input adjustment.
Actual value / Desired value
1. Adjust the process or simulated input signal to a known
value below 50% of the engineering range.
2. If the 'Actual value' (in engineering units) is different from
expected, set the 'Desired value' to the correct value.
3. Repeat steps 1 and 2 for a value above 50% of the
engineering range.
4. Repeat steps 1 to 3 for each input.
Reset adjust
Resets the Offset adjust to zero and the Span adjust to 1.
