All-Test Pro 33IND Electric Motor Tester
The AT33IND instrument is the PERFECT TOOL for trouble shooting, inspection of incoming or stored motors before installation or repair and shows the complete condition of the Stator Windings, the Rotor, Contamination, Ground Fault and Connections
EASY AND QUICK TEST TO CHECK YOUR ELECTRIC MOTORS
This instrument presents an exciting break-through in off-line (de-energized) 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 analyze captured data with.
NO NEED TO CARRY ALONG HARD TO READ USER MANUALS How to proceed is shown step by step on the screen and virtually anybody who can read can do the testing and understand the results. The unit can be used stand-alone or with software, which enables you to see all the underlying data from the test. For accuracy see our specifications.
TWO TESTS IN ONE 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 gives you the information whether any change in Stator or Rotor has occurred between prior test (baseline) and the present test. It measures Resistance, Inductance, Impedance, Capacitance and Phase Angle. The fault indicator is not dependent on Rotor position. Meg-ohm-test with 500 and 1000 V reading up to 999 Mohm is standard. 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.
DYNAMIC TEST BY ROTATING SHAFT The AT33IND Dynamic Test analyzes 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. If the Static test needs to be further evaluated, or if no baseline is available a Dynamic test should be done. The DYNAMIC TEST is done with the rotor shaft disconnected to the machinery. It measures in real time, during the manual rotation of the shaft, several measurements. Any problem is easily recognized by even inexperienced operators. It also collects data used for a “signature” of the Stator and Rotor and these signatures allow for a more in-depth evaluation by an experienced user and supports data of other faults showing in the report
