UT501A Insulation Resistance

UT500 series insulation s are used to measure the insulation resistance of electrical  equment 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 s, power cbles, arresters and other electrical equment 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 equments such as transformer, electric hines, cables, switches, electrical appliance, a ideal tool for electric maintenance, testing and . 1. 2000 count LCD display, overload indication, backlight 2. AC voltage measurement, auto power off 3. Auto discharge 4. Continuous measurements mode, red warning light and function
