Channel Calibration
Calibration Manual Temperature Input
This setting allows a different fixed temperature
value to be used when calibrating. Makes it easier to
calibrate a sensor outside of the process
environment.
NB. If the manual temperature input is changed in
the channel setup menu then the calibration manual
temperature is changed to the same value.
Only available when the temperature compensation
mode has been set to manual in the channel setup
menu.
