2132/2116 Indicator

MC06 – 1.03 3

2 USER CALIBRATION

The indicator 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 or 2116 allows for a user 2-point calibration. This setting is password protected to avoid

accidental alteration.

Page to iP, scroll to CAL.P, and use Up  to alter the password. The password is 3. If the correct

password is entered, the display shows PASS. Scroll to CAL and use  or  to observe the setting

FACt (factory values, as manufactured) or USEr (user values). Change to USEr.

NOTE: before checking the calibration of the indicator, or of the complete system, remember to

reset the 2132 or 2116 to factory calibration values by setting the CAL.P parameter to FACt.

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

should be Pnt.L=400, OFS.L=3, Pnt.H=1000, OFS.H=5.

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

would be appropriate.

Fig 4 gives a graphical representation of the 2-point calibration.
