This handheld digital insulation resistance tester incorporates a 700V AC & DC True RMS voltmeter and continuity testing with a selectable 20mA or 200mA test current. It is designed to measure Insulation Resistance, Continuity, and Voltage. With a safety rating of 600V CAT IV and IP 54, it can perform insulation resistance testing at 250, 500, and 1000V measuring values up to 40GΩ.
This Megohmmeter has features like a Timer and Lock function that allow you to operate it hands free. It has an automatic safety check that protects both the user and the meter with both audiovisual signals and a test inhibition when >25V is registered.
