Learn more by watching our Major Tech MT577 | Diagnostic Insulation Tester 10kV | Metal Case video.
The Major Tech MT577 is a high-performance 10kV diagnostic insulation tester designed for professional electricians. This microprocessor-controlled device features a large 4-bit backlit display and provides precise insulation resistance measurements up to 35TΩ.
With test voltages ranging from 250V to 10kV and a short circuit current output of up to 6mA, the MT577 is perfect for testing insulation on rotating machines, transformers, cables, high-voltage generators, electric circuits, and surge arresters.
It includes advanced functions like Dielectric Absorption Ratio (DAR) and Polarization Index (PI) indication, auto-ranging, adjustable test times, and data storage for up to 500 recordings. The robust design, auto power-off feature, and ability to measure up to 750V AC and 1000V DC make the MT577 an essential tool for field use.
Q: What voltage range does the Major Tech MT577 cover?
A: It covers insulation test voltages from 250V to 10kV with increments of 50V.
Q: What is the maximum insulation resistance the MT577 can measure?
A: The MT577 can measure insulation resistance up to 35TΩ.
Q: Can the MT577 store test results?
A: Yes, it can save up to 500 test measurement results in its memory.
Q: Is the MT577 suitable for field use?
A: Yes, it is housed in a robust case for extended field use and powered by 12.6V Lithium batteries, with data transferable to a PC via optical USB.
