The Megohmmeter Model 6536 is a handheld, battery powered, multi-function 100V digital insulation resistance tester. It is designed to measure Insulation Resistance, Continuity, Resistance and Voltage. With a safety rating of 600V CAT IV and IP 54, the Model 6536 performs insulation resistance at a variable voltage between 10 and 100V with a 1V increment measuring insulation values up to 20GΩ. Meter also incorporates a 700V AC & DC True RMS voltmeter and continuity testing with a selectable 20mA or 200mA test current. The Model 6536 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. Alarms function is also standard.Large digital/analog multi-function display provides clear and easy readings enhanced by a bright blue electroluminescent backlight. A magnetic stand holds the meter to a metal surface or cabinet during the test.Optional Remote Test Probe accessory with flashlight simplifies repetitive testing and helps access hard-to-reach, poorly lit, test areas.Optional ESD Floor Test Kit to test and verify flooring designed to control electrostatic discharge. The Model 6536 is designed for special applications where the voltage needs to be set accurately in 1V increments for testing.
