Frequency Check (In Hertz); Calibration Of The Inductive Pan Sensors - GE JP938 Technical Service Manual

Frequency Check
(in Hertz)
To check the frequency of a specific pan sensor,
press the (-) key of that element while in Techni-
cian Mode. H will display in the window of the
specific surface element. The frequency will
appear in the timer display.

Calibration of the Inductive Pan Sensors

Calibration of the inductive sensors is performed
to permanently store the pan detection thresholds
in a new logic board that has never been cali-
brated. Calibration is also performed to update the
pan detection thresholds due to a physical change
in the pan detection circuit, wiring, or sensor.
Calibration of the inductive sensors is necessary
and must be performed when any of the radiant
surface elements (with an inductive sensor) are
replaced or when the logic board is replaced.
Note: The procedure for calibration of the induc-
tive sensors can be found in the Mechanical
Disassembly section.
