The hand-held ALL-TEST PRO 31 is an excellent trouble-shooting tool that will test a wide variety of motors. The AT31 will find winding faults such as turn to turn and coil to coil, along with grounded windings. The rotor test helps you detect rotor problems such as broken rotor bars and eccentricity.
One of the unique feature of the AT 31 is the instrument will perform a quick pass/fail rotor test (by turning the motor shaft), and will measure EMI.
Measurement results can be entered into our optional Condition Calculator software. The software will perform an unbalance calculation and report back on the condition of the winding, plus will allow the results to be stored and printed. However, the software does not perform data trending.
