For insulation resistance test, you can change the test voltage among 250V, 500V and 1000V. It can also be used to test ACV, resistance which is less than 200Ω, and test for continuity. You can use it to test transformer, motor, cable, switch, electrical appliance as well as to do insulation resistance test. Features & Benefits:

True measurement of speaker systems actual impedance at 1kHz

Three test ranges (20Ω / 200Ω / 2000Ω) allow testing of home theater and commercial sound systems
