Calibration – Menu 4.10
This menu allows the calibration of the current outputs. This is always factory set before shipment. It only
requires performing if any of the configuration for outputs, or output modules have been changed.
I1 5mA Fct. 4.10.1.
Injects 5 mA on the output terminals for the first current output.
I1 18mA Fct. 4.10.2.
Injects 18 mA on the output terminals for the first current output.
These values can be measured at the receiving instrument / control system and may be adjusted by
pressing the → button again. The output may then be adjusted to read the correct amount at the receiving
end. This adjustment can also be used to compensate for losses due to long cable runs.
For the second and third current outputs (if fitted) the calibration can be performed in Fct. 4.10.3. to Fct.
4.10.6.
