The Kyoritsu 3125A is a digital, high voltage insulation tester, capable of testing insulation resistance up to 5kV. Simple to operate, the 3125A insulation tester features a large digital display with backlight, and also has the functionality to test both the polarization index and dielectric absorption ratio.
The Kyoritsu 3125A permits a wide range of insulation testing up to 1 teraohms across 5 voltage ranges up to 5kV (250V, 500V, 1000V, 2500V and 5000V). An indication of the output voltage and discharge voltage is displayed on the screen. A filter function is also present to aid in the reduction of noise interference and obtain stable measurements.
In addition, the 3125A model has the capabilities to perform polarization index (PI) and the dielectric absorption ratio (DAR) testing.Both AC and DC voltage can be measured by the Kyoritsu insulation resistance meter, between 30 and 600V.
The 3125A megohmmeter features a live voltage warning for safety and auto power off to preserve battery consumption. Incorporating a large digital display with bar graph indication and back light, the Kyoritsu 3125A is supplied with a 3m line probe, 3m earth cord, 3m guard cord, a hook type prod, batteries and a hard carry case.
