Offset
The last selection for each channel is Offset. This parameter is normally left at zero.
The Offset is an optional fixed value that can be used to adju st for differences in therm ocouples
when the configured eng ineering units are either d egr ees C or degrees F. For example, i f a
thermocouple reads 25 . 3 degrees C when the actual temp er at ure is known to be 25.0 degrees C, a
value of -30 would be entered to cause the thermocouple to read 25.0 degrees.
The value contains two decimal places and should be supplied in the units specified by the Range
Type. The value is applied before high and low alarm checks.
