10A DC Resistance Tester
The YZZ-10A DC Resistance Tester is an essential testing instrument in power test requirements, serving as a high-precision replacement for DC single and double-arm bridges. The tester internally adopts precise constant current power supply processing technology. The YZZ-10A DC Resistance Tester uses a four-and-a-half-digit LCD to display measurement results and a three-and-a-half-digit LCD to display the current ambient temperature or output current value, ensuring clear readings even under strong light. It also features an automatic discharge function to avoid generating arcs. The YZZ-10A DC Resistance Tester offers fast measurement speed, high accuracy, strong anti-interference capability, compact size, and is unaffected by human factors. The output current has five gears for manual quick adjustment, with a measurement range of 1μΩ-2kΩ and an error not exceeding 0.2%. The YZZ-10A DC Resistance Tester is an ideal device for measuring various inductive load resistances such as power transformers, low-voltage switch contact resistance, wire and cable or weld joint resistance, as well as DC resistance of high-power inductive equipment. Its measurement speed is more than a hundred times faster than a bridge. The YZZ-10A DC Resistance Tester is powered by AC supply, suitable for field use and harsh mountain forest conditions.
