Compressor Components
• • • CAUTION • • •
Do not connect Mega Ohmmeter while the compressor is under a vacuum; this may cause damage.
1. Place the leads on terminal 1 & 3 of the pressure/temperature sensor.
2. The temperature sensor is a 10KΩ @ 77°F (25°C) negative temperature coefficient (NTC)
thermistor.

3. Compare the compressor pressure readout to the gauge pressure value.
4. The values should not be greater than the following:
• Suction Sensor - 1.7psi (12kPa)
• Discharge Sensor - 7.25psi (50kPa)
Running Check
1. Connect to the compressor with the SMT.
2. Compare pressure and temperature readout from compressor to readings from a calibrated
gauge set and thermometer placed as close to the sensor location as possible.
