Instrument Calibration Temperatures
All RTDs are 100 ohm Pt and are scaled as such via hard-coded configuration in the PLC input module. The
Raw T Reading is defined as the scaled value from the RTD input module.
Set the Offset to zero unless required otherwise. The offset value adds to the raw temperature reading
scaled value to result in the Calibrated Value which is used for control.
