Electrical workers often need to test the DC resistance value of power transformers and distribution transformers, you need to use DC resistance tester, traditional DC resistance tester due to large size, heavy weight, not suitable for testing in the field, so is there a portable DC resistance tester, can be handheld measurement? Kingrun has developed a handheld DC resistance tester for this purpose, the main feature of the device is small size, handheld operation, and high accuracy.
JYR-10S handheld winding resistance tester,with built-in lithium battery,test 3 phase simultaneously.with Automatic phase change function. suitable for transformers,electrodetaciators, electromagnetic operating mechanisms and other inductive test products, but also for wire, switch contacts, relay contacts and other impedance test products measurement.
