The TPI digital megohmmeter is an insulation tester with three test voltages—250, 500, and 1,000V—for measuring insulation resistance to 2,000MΩ to indicate the condition of windings or cables in motors, switchgears, electrical installations, and other insulated equipment, and it also measures low-resistance to 200Ω and indicates when a live circuit is detected. The meter is available in a model (B0095XEX38) that measures AC voltage to 600V. When a live circuit is detected, the meter sounds a buzzer, and the model with AC voltage measurement displays the voltage reading while the model without AC voltage measurement lights an indicator. When measurement is complete and the test button is released, residual voltage is automatically discharged from the circuit under test. The test button can be locked for extended measurement sessions. The meter has an LCD and a low-battery indicator that signals when the batteries need to be replaced. The model with AC volts measurement (B0095XEX38) is rated for category (CAT) III installations to 600V, which covers equipment in fixed installations, such as switches in the fixed installation and some industrial equipment that is permanently connected to the fixed installation. The model without AC volts measurement (B0095XEWC0) is rated for CAT II installations to 1,000V, which covers energy-consuming equipment connected to a fixed installation, including household, office, and laboratory appliances. The meter comes with a set of UL listed silicone test leads with alligator clips, a set of 6ft. test leads with large alligator clips, a neck strap, and instructions. Megohmmeters are commonly used for electrical maintenance and testing in industries such as HVAC, transportation, manufacturing, mining, and utilities, among others.SpecificationsMaximum insulation resistance measured2,000MΩTest voltages250V, 500V, 1,000VMaximum low-resistance measured200ΩMaximum AC voltage measured600V for model B0095XEX38 (with AC volts)Installation ratingCAT III, 600V for mod...
