4.14 User Calibration
The controller is calibrated for life at manufacture against known reference sources, but there may
be sensor errors or other system errors. User calibration allows compensation for such errors, and
the 2132 allows for a user 2-point calibration. This setting is password protected to avoid
accidental alteration.

NOTE: before checking the calibration of the controller, or of the complete system, remember to
reset the 2132 to factory calibration values by setting the
To enter a user calibration, scroll to each or the following parameters in turn and set the desired
values.
Pnt.L
low temperature for which an offset is to be entered
OFS.L
offset value for the low temperature
Pnt.H
high temperature for which an offset is to be entered
OFS.H
offset value for the high temperature
Example: the controller reads 3°C low at 400°C, and 5°C low at 1000°C. The parameter values
Pnt.L=400

Negative or positive values can be entered: if
the controller is reading high, negative offsets
would be appropriate.
