The All-Test Pro 31 is the latest test instrument for electric motors, coils and windings.
The All-Test Pro 31 is the latest test instrument for electric motors, coils and windings.
It replaces the popular All-Test III, which has been sold in thousands of units since introduced in 1993.
The handheld All-Test Pro 31 incorporates tests for faults to ground, internal faults such as turn-to-turn and coil-to-coil and phase balance.
Electrical interference from residual or stray currents from the test object or surrounding power sources is measured by an included EMI test.
Test frequencies can be selected in the range 25-800Hz, which enables the instrument to test fractional as well as large AC/DC motors, generators and transformers, multiple or single phase.
In addition, the instrument features a revolutionary, patented rotor test, which quickly finds broken rotor bars and casting voids.
The instrument is handheld and weighs only 450g.
It provides safe, offline testing on de-energised machinery and will save the user downtime, unnecessary repairs and on utility bills.
It will take the guesswork out of motor troubleshooting and management.
