3. Enter Calibration Mode. The lower main display will then show Input Type Number,

in the form:

iP_I


and the message display will show:

Calib


Using the UP/DOWN keys, change the input type number as required (see Table 12-1).

NOTE: If required, only one input type may be calibrated. Exception: If it is required to
calibrate the thermocouple input (Input Type 5), it is necessary first to calibrate the DC
0 - 50 mV input (Input Type 1).

4. Press the PROF key to change the lower main display to show: _ _ _ _

After a few seconds, the lower main display will either (a) return to the initial Input Type
Number display if calibration was successful, or (b) display:

FAIL


In the latter case, the link jumpers and wiring should be checked.

5. To calibrate all inputs, repeat Steps 1 to 4 for each of the other input types (see

Table 12-1) until all five input types have been successfully calibrated.


The universal input calibration procedure is now complete.
