Overview
The All-Test Pro 31 motor testing kit is a deenergized motor circuit analysis (MCA) instrument designed for troubleshooting and maintenance of AC induction motors. The handheld All-Test Pro 31 will test a wide variety of motors and transformers and will find winding faults such as turn-to-turn and coil-to-coil, along with grounded windings. This used unit comes equipped with V4 Condition Calculator software and a 115V charger adapter, making it ready for immediate deployment in industrial maintenance programs.
Key Features
- Rotor test helps detect rotor problems such as broken rotor bars and eccentricity
- Measures impedance (Z), phase angle (Fi), current/frequency response (I/F), insulation to ground resistance (500V or 1000V and measure to 500 meg-ohm), perform quick pass/fail rotor test by turning motor shaft, and measure EMI
- Measurement results can be entered into Condition Calculator software which performs unbalance calculation and reports on winding condition, allowing results to be stored and printed
- Conducts full evaluation of rotor health by detecting stator and rotor faults in AC motors less than 1,000V
- Portable handheld design for shop or field testing
Technical Specifications

Typical Applications
Test new and rewound motors before installing to ensure they are good; test motors during shutdown to detect developing faults; positively troubleshoot motor and drive trips to identify the problem area in motor, drive, overload, cabling. The All-Test Pro 31 is ideal for:
- Predictive and preventive motor maintenance programs
- Motor troubleshooting when drives or systems shut down unexpectedly
- Testing motors in the shop, storage, or field without de-energizing live systems
- Identifying motor winding degradation before catastrophic failure
- Field diagnosis of motor circuit integrity and rotor health
