This product is discontinued. The ALL-TEST PRO 34™ is a recommended alternative.

The ALL-TEST Pro 33 IND™ is used to test AC Induction, squirrel-cage rotor motors <1000V for: contamination, winding faults such as turn & coil to coil, open connections, ground faults and evaluates the condition of the rotor.

This instrument presents an exciting breakthrough in de-energised testing. Within minutes the operator can get a complete picture of the condition of a motor without having to stress-test the windings or use other more expensive or elaborate instruments, which can be difficult to operate and analyse captured data with.

The instrument can be used in two modes: Static and Dynamic. Both quickly collect data in auto mode and there is no need to operate a lot of difficult to understand buttons.

THE STATIC TEST can be performed at the control panel and takes only a few minutes per motor! It tests “the whole loop”, i.e. cable, connections and stator/rotor from the starter/motor drive. No need to disconnect drives and machinery for the phase to phase test. It reports whether a change has occurred between a prior test (the baseline) and the present test.

Use this as an initial test reference as a motor specific parameter value, and to confirm the health of an Induction motor. Subsequent test results can be immediately compared to the reference TVS™ to instantly show developing problems or changes with the stator or squirrel-cage rotor.

It measures Resistance, Inductance, Impedance, Capacitance and Phase Angle. The fault indicator is not dependent on Rotor position.

The Static test is compared to a base-line test that can be retrieved from “Reference Value Static” records in the instrument, or from the optional software. Meg-ohm-test with 500 and 1000 V reading up to 999 Mohm is standard.


The AT33 IND™ Dynamic Test analyses the results for you by showing Bad, Warning or OK for Resistance, Stator, Rotor and Contamination. It is developed for testing <1000V induction motors with squirrel cage rotor.
