    Complete Motor Health Assessment

    The electrical health of all motor components is evaluated, including, but not limited to induction windings, rotors, DC field windings and armature, field and rotor coils in synchronous motors, primary and secondary windings in transformers, and all associated connections and cables.

    Safe Testing

    The ATPOL III™ connection accessory offers significant advantages over conventional methods for collecting energized testing data while the motor is under load. The quick connection allows for testing without opening electrical panels, eliminating the need to suit up in bulky protection gear. Safety, ease of use, accuracy, and superior diagnostic results make the ATPOL III™ the best accessory for ESA motor testing.

    Surpassing The Highest Standards

    The ATPOL III™ has passed the highest standards for CAT III 1000V. The CAT IV 600V rating signifies it is suitable for testing at the service entrance (≤ 600V).

    Comprehensive Hand-held Energized Motor Testing

    The ALL-TEST PRO On-Line II™ is the most complete energized motor and power diagnostic instrument available today – all in a handheld, lightweight package. It delivers superior AC diagnostics for the evaluation of electrical and mechanical stator health, rotor health, air gap, and the health of the entire driven load (belted, geared, bladed, etc.). This instrument also provides excellent diagnostics for DC motors, generators and transformers.

    The ATPOL III™ offers many software and data analysis advantages compared to the competition, including key determinations that are made automatically, including:

    • Line frequency, running speed and pole pass frequency
    • Software automatically looks for patterns related to stator slot and rotor bar fault frequencies
    • Automatic detection of static or dynamic eccentricity faults
    • Evaluation of incoming power, including harmonics
    • Calculates efficiency for AC induction & DC motors
    • Power analysis includes sag/swell and transient detection, plus energy consumption data logging


    • Fast – motor tests take only 60 seconds after connection to load
    • Testing distance – virtually unlimited between motor and load (including submersible equipment)
    • Early alert – detects faults at early stages before motor and motor system failure
    • User safety – Bluetooth® wireless communication enables remote operation including data collection
    • Quick asset management – Test Plan Manager allows for route-based testing and trending

    Testing Capabilities

    Test all types of electrical motors of any voltage, including AC (induction and synchronous) and DC (series, shunt, and compound), as well as transformers, generators, traction motors, and machine tool servo motors.

    Obtain Optimal ROI

    Finding a motor fault before it breaks can save your organization countless hours of downtime and thousands of dollars in savings. The ATPOL III™ is actually two instruments in one – a complete Power Quality Analyzer (PQA) and a complete Electrical Signature Analyzer (ESA). When in PQA mode, it can be used for:

    • Energy data logging
    • Harmonic analysis
    • Voltage and current charting
    • Viewing waveforms
    • Waveform sags and swells, transient, and event captures

    When in ESA mode, it can evaluate the condition of the:

    • Incoming power
    • Control circuit
    • Motor and the driven load

    The test results are easily stored and can be trended for condition-based maintenance or predictive maintenance purposes.

    Improve the DETECTION PHASE in your predictive maintenance testing program. Faults related to incoming power, the control circuit, the motor itself, and the driven load are detected, and can then be trended for predictive maintenance purposes and troubleshooting.
