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, Resistance and Voltage and has an Alarm function. With a safety rating of 600V CAT IV and IP 54, it can perform insulation resistance at variable voltage between 10 and 100V with a 1V increment measuring values up to 20GΩ.
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.
The 6536 is designed for special applications where the voltage needs to be set accurately in 1V increments for testing.
