100V/250V/500V/1000V rated test voltage, with a measurement range of up to 2000M and has the ability to measure AC voltage. Wide measurement range, with locking button. 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. Widened dial design, indication range, and more accurate fault diagnosis. The dial illumination function is convenient to use in dim environments and accurately read measured values. Automatic discharge function: After the measurement is completed, it automatically enters the discharge state to avoid caused by residual charges in the circuit. Add a transistor withstand voltage measurement scale to directly read the withstand voltage value (load voltage) of the tested material. It is used to measure the insulation resistance of electrical equipment and insulation materials such as , motors, cables, switches, and electrical appliances, and to maintain, test, and verify famous electrical equipment.
