TKZZ-2A DC resistance tester is also known as transformer DC resistance tester, 2A DC resistance tester, transformer DC resistance meter, and 2A transformer DC resistance tester. TKZZ-2A DC resistance tester is an indispensable testing device in power testing. It is mainly used for DC resistance testing of windings in transformer AC/DC connection and overhaul projects. The TKZZ-2A DC resistance tester uses precise constant current power supply processing technology internally and displays data with three-and-a-half-digit and four-and-a-half-digit LCD screens. The TKZZ-2A can also display the current ambient temperature or output current value. The TKZZ-2A transformer DC resistance tester also has an automatic discharge function to avoid generating arcs and ensure the safety of operators.
The TKZZ-2A DC resistance tester is easy to use, with fast data measurement speed, high test data accuracy, strong anti-interference capability, small size, and test data not affected by human factors. The output current has six adjustable gears, and the resistance measurement range is 1μΩ-2kΩ, with high accuracy and error better than 0.2%. It is an ideal testing instrument for measuring DC resistance of power transformers and various inductive load resistances, switch contact resistances, wire and cable or weld joint resistances in power preventive tests. Compared with traditional double-arm bridges, the TKZZ-2A transformer DC resistance tester is more than a hundred times faster in testing speed, making it a high-precision replacement product for DC single-arm and double-arm bridges. It can be powered by a built-in rechargeable battery pack or AC power supply, making it a good helper for field electrical testing and construction.
