Datasheet - AEMC - 6522


The Megohmmeter Model 6522 is a handheld, battery powered 1000V digital insulation resistance tester. It is designed to measure Insulation Resistance, Continuity and Voltage.
With a safety rating of 600V CAT IV and IP 54, the Model 6522 performs insulation resistance testing at 250, 500 and 1000V measuring values up to 40GΩ. It also incorporates a 700V AC & DC True RMS voltmeter and continuity testing with a selectable 20mA or 200mA test current.
The Model 6522 includes a Timer and Lock function which allows the user to operate the unit hands free.
Automatic safety check protects user and meter with audiovisual signals and test inhibition when >25V is present on test sample.
Large digital/analog multi-function display provides clear and easy readings enhanced by a bright blue electroluminescent backlight.
Optional Remote Test Probe accessory with flashlight simplifies repetitive testing and helps access hard-to-reach, poorly lit, test areas.
The Model 6522 is a great tool for basic insulation testing up to 1000V.
