The 380260 is a handheld megohmmeter designed to measure insulation resistance in motors and electrical systems with a maximum test voltage of 1000V. It features a dual backlit display that simultaneously shows both insulation resistance and test voltage, with selectable test voltages of 250V, 500V, and 1000V to accommodate various testing requirements. The device offers insulation resistance measurement ranges up to 2000MO with a maximum resolution of 0.1MO and basic accuracy of ±3%, along with a low resistance (Lo O) function for testing connections and AC voltage testing capability. Additional features include a lock power-on function for hands-free operation, data hold to freeze readings, and auto power-off functionality. The meter is housed in a double-molded case for durability, powered by 6 AA batteries, and comes complete with heavy-duty test leads, alligator clip test lead, hanging strap, and hard carrying case, making it ideal for field technicians and maintenance professionals requiring portable insulation testing.
