C (1): Degree Celsius
- (2): No unit
IN1
Max. value of PV
input range
Set the instrument input range (RL1 < RH1).
- For temperature input -
Set the range of temperature that is actually controlled.
- For voltage input -
Set the range of a voltage signal that is applied.
The scale across which the voltage signal is actually controlled
should be set using the parameters Maximum Value of PV Input
Scale (SH1) and Minimum Value of PV Input Scale (SL1).
