Featuring a 2000 count backlit LCD, continuous measurement modes, and safety alerts including a red warning light and buzzer, it supports advanced diagnostics like PI and DAR measurements with auto resistivity calculations. Ideal for electrical maintenance and testing of transformers, motors, cables, and more, it combines precision, safety, and convenience in a compact 500g device. ## Description UT502A Insulation Resistance Tester (Test Voltage from 500V to 2500V) UT502A Insulation Resistance Tester UT500 series insulation testers are used to measure the insulation resistance of electrical equipment and household appliances. This is done by measuring the insulation resistance between electrical circuits or between circuits and ground. UT500 series can measure insulation resistance, AC Voltage, low resistance, PI (Polarization Index) and DAR (Dielectric Absorption). These are dieal tools for ensuring transformers, genera-tors, high voltage motors, power capacitors, power cbles, arresters and other electrical equipment that can oprate in a safe and accurate manner. Applications: It is used for insulation resistance measurement for insulation materials and various kinds of electric equipments such as transformer, electric machines, cables, switches, electrical appliance, a ideal tool for electric maintenance, testing and inspection. 1. 2000 count LCD display, overload indication, backlight 2.
