Transformer DC Resistance Tester
Introduction
KRI9310 DC resistance tester is portable and automatic tester, which is applicable for the inductive test objects (such as distribution transformers, instrument transformers, reactors, etc) and the resistive test objects (such as contactors of switches, contactors of relays, wires, etc).
Features
- 6 ranges of output current for selection;
- Automatic calculation function, input the test object material (copper/aluminum) and its temperature, the DC resistor tester will automatically calculate the resistance @ standard temperature (20ºC,75ºC or 120ºC);
- 500 test data storage;
- USB port to download the test data to USD flash disk;
- Protection- discharge alarming, over-heat alarming;
- Professional probes as optional to measure the real-time temperature.
