Aneng MH11 Insulation Resistance Tester is a digital megohmmeter (insulation resistance tester) designed for electricians and technicians to test the integrity of insulation in motors, cables, and power facilities. It works by injecting a high-voltage DC signal and measuring the resistance of the material—essentially checking for "leaks" in the electrical insulation.
Test Lock Function: Allows for continuous measurement without holding down the "Test" button—perfect for long-duration insulation monitoring.
Automatic Discharge: Once the test is complete, the meter automatically discharges the stored electricity in the capacitive circuit for safety.
High-Voltage Warning: Features a dedicated indicator light that illuminates when high voltage is being outputted to warn the user.
Backlit Display: The large LCD is easy to read in dark environments like electrical closets or industrial basements.
