How to Check Sensor Resistances Make
ice slurry. To do this, fill a cup with ice
(preferably crushed), then add water and a
teaspoon of salt to make a slush. Mix thor-
oughly and allow to sit for 2 to 3 minutes.
This will give you a 32*F reference. Now,
lower the sensor into the mixture and leave
for about 1 minute, then check the resis-
tance. It should be very close to 13,300
ohms. Before reinstalling the sensor, be
sure to rinse it with fresh water and dry it.
