Offset Adjust (
Adjust
)
This parameter allows the user to select an offset adjustment to the temperature being displayed. Offset
adjustment values can be either positive or negative and can be any number within
50.0
F (+27.8
C). The
offset adjustment value is programmed through the
Adjust
menu.
The offset adjustment feature can be useful to compensate for errors due to thermocouple junctions or
excessive lead wire resistance in RTDs.
Note: The offset adjustment value is not reset to zero when the type of temperature sensor is changed
(i.e. TC type or RTD curve). Celsius/Fahrenheit conversion must be made manually by the user.
