Error:
Likely cause: Solution:
The new coefficients calculated
by the unit in the CALIB. Proc.
deviate by more than 4% from
the standard values. The
calculated coefficients will be
ignored:
Check the accuracy of the
reference thermometer used for
calibration and repeat the
calibration/adjustment procedure.
If the calibrator shows ERROR
0002 again, the internal RTD-, TC
sensor or the CONTROLLER PCB
is defective.
Error:
Likely cause: Solution:
Defective CONTROLLER PCB: Replace the CONTROLLER PCB
and then adjust and re-calibrate
the unit.
Error: Temperature reading is acting bizarre (CTC-1200 A
only)
Likely cause: Solution:
The thermocouple has been
wrongly polarised.
Check the polarity of the
thermocouple.
