Universal Motor/Transformer & Coil Tester

This patented instrument, All Tester, is a versatile tool for the motor and transformer users, manufacturers and repairers. One can use it either as a diagnostic help on faulty or suspected machines or as a stage inspection instrument. It is useful for testing all types of motors-single phase or three phase, AC squirrel cage or slip ring or DC motors. Motor studies have shown that sudden looking breakdowns actually start as a small insulation fault that cannot be detected by conventionally used instruments. This fault causes intense spot heating and hence the fault worsens and ultimately results in the burn out. With All Tester, one can readily locate such faults and therefore can take planned action and minimise downtime. There is also a function to test earth leakage by applying a high voltage pulse. All Tester can even measure microfarads and the loss angle of the start and run capacitors used with single phase motors and thus certify the complete health of motors.
