The Megohmmeter Model 6524 is a handheld, battery powered, multi-function 1000V digital insulation resistance tester with onboard memory. It is designed to measure Insulation Resistance, Continuity, Resistance, Frequency and Voltage. With a safety rating of 600V CAT IV and IP 54, the Model 6524 performs insulation resistance at 50, 100, 250, 500 and 1000V measuring insulation values up to 200GΩ. Meter also incorporates a 700V AC & DC True RMS voltmeter and continuity testing with a selectable 20mA or 200mA test current. PI, DAR and Alarms function are standard. The Model 6524 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.áLarge 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. With the possibility to save up to 300 tests in memory, the Model 6524 is a great tool for most of the insulation tests in the shop or in the field where a wide range of voltages, up to 1000V, are desired.
