Insulation resistance tester, high-precision digital insulation voltage meter

The insulation resistance tester (or high-voltage insulation tester) is a specialized instrument for measuring insulation resistance. It is an ideal testing tool for measuring the insulation resistance of large transformers, generators, high-voltage motors, power capacitors, power cables, surge protectors, and more. Features: Automatic trip voltage function. Suitable for measuring the insulation resistance of various electrical equipment and insulating materials such as transformers, motors, cables, switches, electrical appliances, etc. It is suitable for the maintenance, repair, testing, and verification of various electrical equipment. Variable rated output voltage: The rated output voltage can be switched using the function buttons (1000V switches between 50V, 100V, 250V, 500V, and 1000V). High voltage indication: The device is equipped with a red LED indicator that signals the presence of high voltage in the instrument. There is a risk of electric shock; the operator must pay particular attention to safety. Low battery voltage indicator. Battery powered, easier to use. Easy to operate and carry. High charging capacity, output short-circuit current < 1.8 mAh. Completely protected circuit, no fear of voltage backlash, output short-circuit protection. It can measure AC/DC voltage 10V-600V, AC voltage frequency 40Hz~70Hz. Dustproof and moisture-proof structure, suitable for outdoor operation.
