JHR5110A DC Resistance Tester: It is an industry-oriented DC resistance tester; a fully automatic, digital portable measuring instrument developed with multiple technologies. This instrument is not only suitable for inductive test objects such as distribution transformers, mutual inductors, reactors, and electromagnetic operating mechanisms, but also for resistive test objects such as wires, switch contacts, and relay contacts. For dry-type transformers and amorphous alloy transformers, since the low-voltage coils are wound with copper foil and have extremely low resistance, this instrument increases the current to 10A, solving the problem of measuring low-value resistance.

1 Introduction
