FieldDiagnostics.com

The Service Assistant is shipped with a "Quick-Test Array" including suction line, liquid line, and outdoor ambient temperature sensors.
- Appropriate for testing most residential and light commercial units without installing the sensors permanently.
- Suction and liquid line temperature sensors and shipped with a mounting clip designed to be installed and removed quickly on a wide range of pipe diameters.
- Outdoor ambient sensor is short and designed to stay near the Service Assistant. Hang the Service Assistant in front of the condenser coil for accurate measurements.
The "Full Array" or "Single Stage Array" is sold separately and adds four more temperature sensors to the three "Quick-Test Array" sensors including discharge line, condenser outlet air, return air, and supply air temperature sensors.
- Includes a memory chip in the connector for storing unit and test information at the unit.
- Permanently install on units with one compressor.
- Carry with the Service Assistant for testing larger commercial units requiring longer wire lengths.
- Use for testing water cooled units by substituting the "ambient air" sensor for inlet water temperature and "condenser outlet air" temperature for condenser outlet water temperature.
- Suction, liquid, and discharge line sensors are shipped with wire ties for permanent installation.
The "2 Stage Array" is also sold separately and has all the "Full Array" sensors plus three more temperature sensors for the suction, liquid, and discharge lines of a second compressor.
- Includes a memory chip in the connector for storing unit and test information at the unit.
- Permanently install on units with two compressors.
- Suction, liquid, and discharge line sensors are shipped with wire ties for permanent installation.
