Using DTMD v5.4.1 it is possible to "force" the sensor analog output to a fixed value.
This is useful for verification of the sensor analog output calibration and also the control system input calibration - if a calibrated multimeter is used in the "loop":
Access via Loop Maint. > Maintenance > Sensor 1
Special Note
The following sensors that are compatible with this software can also have the analog output adjusted using separate "Field-Cal" software:
Raytek MM
Ircon Modline 7
Raytek Mi3 (too be confirmed)
Raytek TX (software only available for DOS)
