& Resistance for Type III Sensors

Thermistor Sensor Testing Instructions

1.) Use the resistance column to check the thermistor sensor while dis-

connected from the controllers (not powered).

2.) Use the voltage column to check sensors while connected to powered

controllers. Read voltage with meter set on DC volts. Place the “-” (mi-

nus) lead on GND terminal and the “+” (plus) lead on the sensor input

terminal being investigated.

If the voltage is above 3.3 VDC, the sensor or wiring is “open.” If the

voltage is less than 0.05 VDC, the sensor or wiring is shorted.
