Insulation Resistance Meter Digital Ohmmeter Handheld Insulation Tester Megameter 0-2000MΩ 100V/250V/500V/1000V High Accuracy Megohmmeter Insulation Measurement Instrument Features: 100V/250V/500V/1000V rated test voltage, with a measurement range of up to 2000MΩ and has the ability to measure AC voltage. Wide measurement range, with locking button, easy for you to choose and use. Can measure AC voltage below 500V (full scale linear indication). Low resistance value buzzer alarm, reminding you to pay attention and observe. The battery voltage status indicator light (BATT CHECK light on) also serves as a high voltage indicator for the operation of the megohmmeter. Additional external DC power supply (charging) socket for your convenience. Widened dial design, wider indication range, and more accurate fault diagnosis. The dial illumination function is convenient for you e in dim environments and accurately read measured values. Automatic discharge function: After the measurement is completed, it automatically enters the discharge state to avoid electric shock caused by residual charges in the circuit. Strong output load capacity, with a maximum output short-circuit current of 0.55mA. Add a transistor withstand voltage measurement scale to directly read the withstand voltage value (load voltage) of the tested material. Fully functional, higher accuracy, convenient and reliable operation, it is an excellent electrician testing instrument. Comes with a pair of test leads and alligator clips, good quality zipper bag for carrying and storage. It is used to measure the insulation resistance of various electrical equipment and insulation materials such as transformers, motors, cables, switches, and electrical appliances, and to maintain, test, and verify famous electrical equipment.
