9. SCREEN 9: Offsets
(Changes require username/password)
The offset screen provides a way to calibrate the various measured temperatures, if required.
The offset number can be either positive or negative and is added to the value being measured
by the sensing element. For example, if the Outside Air was reading too low of a temperature,
a positive offset would be used which would increase the temperature displayed. If the value
was reading too high, a negative offset would be used.
It should be noted that any values corrected with offsets are also used internally in the PLC for
calculations.
