This off-line tester applies a low voltage AC signal to the windings, and measures relative impedance, etc.
Your motor drive has shut the system down. Is the problem in the motor, the drive, the connections, or the overload? Maybe you’ve installed a large new motor only to find it won’t run – how could you have detected the fault in advance? Most motor faults start in the end turns of the windings. They can propagate for days or even weeks until the motor trips and finally fails. You’ll never spot them with a megohm meter or a DMM until the motor has failed, and you may still miss them. You need an ALL-TEST III. This off-line tester applies a low voltage AC signal to the windings, and measures relative impedance, phase angle, and performs a current/frequency response test. Compare the balance of the measurements (just like comparing resistance) and you know the condition of the motor. The ALL-TEST III also measures insulation resistance up to 20 MΩ or 1000V test voltages to detect grounded windings and failing insulation. Rotor bar problems are among the most difficult problems to confirm, but not with an ALL-TEST III. Simply connect to one phase while slowly rotating the shaft, to quickly detect broken rotor bars and even eccentricity.
Diagnostic Software Condition Calculator 2.0 is a diagnostic tool that takes the guesswork out of interpreting measurements. Simply enter the data into the PC and view the diagnosis and condition. Also available is a pocket PC, Condition Calculator PPC, sold installed on a Toshiba e330 Palm PC. The e330 is powered by Windows Pocket PC 2002, and also includes Pocket Word, Pocket Excel, Pocket Outlook, and much more. Equipped with 64 MB of RAM and a 300 MHz microprocessor, it has the power and capacity operate additional programs. PC communication is through the included USB port cable or infrared port.

Features
Test new and rewound motors before installing to insure they’re good. dangerous leaks
Test motors during shut-down to detect developing faults.
Positively troubleshoot motor and drive trips to identify the problem area – motor, drive, overload, cabling, etc.
When testing installed motors, most tests can be run from the MCC through even hundreds of feet of cable.
Detects all of the following: – Turn-to-turn faults – Coil-to-coil and phase-to-phase faults – Open phases – Phase unbalances – Broken rotor bars – Grounded windings – Capacitor failures (pass/fail test) – Shorted windings
Works on all sizes of motors—fractional through thousands of HP.
Low-voltage tests are non-destructive
