breaks, and/or kinks. If
found, replace probe.
Determine temperature
of water in cookpot
using a thermometer or
pyrometer placed at tip
of probe.
Is resistance
approximately equal to that
given in the Probe Resistance
Chart for the corresponding
temperature?
Measure resistance
through each of the
previously tested pins
to ground.
Is resistance
5 megaohms or greater
in each pin?
Probe is good.
