In the past, the demand was 1 milliamperes in a short circuit. However, we were asked to increase the short-circuit current to shorten the test time. Its 5 milliamps makes the 3128 very powerful, and it's good for long cables, large motors, generators, etc. shortens the testing time. In addition, the 3128 has a wide range of 35 TΩ and a high voltage of 12 kV. It is user friendly. In the past, only testing could be done with high voltage insulation testers. But now the demand for diagnostic analyzers has increased and therefore our device also has PI, DAR, DD and SV features. The 3128 also has a large screen, bargraph and computer connections. All data can be transferred to the computer. Best of all, you can watch the test in real time and your free software comes with the device. The 3128 has a more robust design and a good power supply. One of the power sources is a DC battery and the other is an AC adapter. Where can 3128 be used? In cables, generators, motors, high voltage circuit breakers (fuses) and more. The 3128 is Kyoritsu's widest range of 12 kV high voltage insulation tester.
