Notes:
1. Use the resistance column to check the thermistor sensor while disconnected 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 “-”(minus) lead on GND terminal and the
“+”(plus) lead on the sensor input terminal being investigated.
If the voltage is above 5.08 VDC, then the sensor or wiring is “open.” If the voltage is
less than 0.05 VDC, the sensor or wiring is shorted.
