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 basic tools to ensure that transformers, generators, high-voltage motors, power capacitors, power cables, dischargers and other electrical equipment can work safely and accurately.

Muy buen funcionamiento. Lo he utilizado en varias ocasiones y funciona muy bien para detectar posibles problemas.Lo unico malo que le veo es la cantidad de pilas que hay que poner, podía llevar batería recargable.
