    MCA Software (Optional)

    Test motor windings on induction motors with the AT34 by ALL-TEST Pro.


    The new ALL-TEST PRO 34™ empowers technicians to efficiently and accurately evaluate motors whether they are in the field or on the shop floor – improving motor reliability, increasing technician and asset productivity, and reducing energy consumption.

    Diagnose ground faults, test stator windings, test cables, and induction motor abnormalities and receive results all on one screen within minutes.

    Initiated from the motor drive or motor starter, Motor Circuit Analysis™ can evaluate the health of a motor in a non-destructed manner. In fact, it can work from up to 1,000 feet away from the motor it’s testing. This device helps companies avoid the hassle of fixing motor failure issues that could have been prevented, and it saves them countless dollars in lost work time due to these problems.

    Complete Motor Health Assessment

    The electrical health of all motor components is evaluated, including, but not limited to induction windings, rotors and all associated connections and cables.

    Patented Test Value Static™ (TVS™)

    Test Value Static (TVS) is a sum calculated from the 3-phase MCA static test and is used as a reference value for the motor. Common types of faults in the rotor and stator windings will change TVS.

    Patented Dynamic Stator and Rotor Signatures™

    Used to evaluate the condition of the stator and squirrel-cage rotor in a single test. Perfect for testing new and repaired motors prior to acceptance.

    Open Connection




    Rotor Faults









    The ALL-TEST PRO 34™ tests AC induction squirrel-cage motors less than 1,000V for abnormalities such as open connection, ground faults, internal winding faults, contamination and rotor faults — much more than a regular digital multimeter or megohmmeter can evaluate in a single test.

    The ALL-TEST PRO 34™ is extremely portable and easy to operate, and it can assess the health of virtually any squirrel-cage rotor mower <1000V within a 1,000-foot range.


    ALL-TEST Pro provides on-site and virtual comprehensive learning experiences that incorporate theory, new technologies, and practical field applications to educate attendees in the scope of motor diagnostics and comprehensive testing, including Motor Circuit Analysis™ (MCA™) and Electrical Signature Analysis (ESA).
