DC resistance test TKZZ-3A DC resistance tester transformer winding transformer in the transfer, overhaul and change the tap, the essential pilot projects. By measurement of transformer winding DC resistance, you can check out the quality of the welding wire or connection, between the windings or without turn short circuit or open circuit, and tap the contact is good and so on. Before the measurement of linear resistance are used to measure the QJ44 double bridge, and the bridge of such a measuring current in milliamps level, measuring the time it takes a very long, but the precision is lower. In order to change this situation, to shorten the measurement time and lighten the workload of testers, the company has developed rapidly TKZZ-3A DC resistance tester. The product is to replace the DC single, high-precision double bridge replacement. The instrument uses an advanced switching power supply technology, the measurement bridge faster than a hundred times, showing some four and a half by the LCD display of measurement results, three semi-LCD display ambient temperature or test current value, to overcome the other similar Products from the LED display value inconvenient drawback of reading in the sun, along with the automatic arc suppression function. The DC resistance tester has a fast speed, high precision, intuitive display, strong anti-jamming capability, small size, low power consumption, stable and reliable test data without human factors and so on. Instrument built-in rechargeable battery pack (12V), AC and DC, easy on-site and field testing. This product complies with DLT 845.3-2004 "resistance measurement devices General Part 3 DC Resistance Tester" requirements.
