CJunct (thermocouple cold/reference junction compensation)
The Model 230/235 calibrator performs automatic cold junction
compensation for both input and output thermocouples. The
automatic cold junction compensation can be disabled if necessary and
a fixed compensation temperature can be entered.
The menu allows you to select either manual or automatic
compensation.
If you select manual and press ENT, you will be prompted to enter the
manual compensation temperature in degrees Fahrenheit.
If you enter 32°F, the calibrator will convert temperature to millivolt
values directly from the standard thermocouple tables. If you select
Auto and press ENT, the Model 230/235 calibrator will use either the
standard internal cold junction compensation, or the optional external
reference junction.
