The measurement of DC resistance is a must-test item in the manufacture of inductive coils such as transformers, transformers, reactors, electromagnetic operating mechanisms, etc., for semi-finished products, finished products factory test, installation, handover test, and preventive tests in the power sector. It can effectively discover the selection of inductive coils, Welding, loose joints, missing strands, wire breaks and other manufacturing defects and hidden dangers after operation. In order to meet the needs of rapid measurement of the DC resistance of inductive coils, our company has developed this DC resistance tester by taking advantage of its own technology. The instrument has the characteristics of small size, light weight, convenient carrying, large output current, wide range, and internal lithium battery power supply. The whole machine is controlled by a single-chip microcomputer, which automatically completes the functions of self-inspection, data processing, display, etc., and has automatic discharge and discharge prompt functions. The instrument has high test accuracy and easy operation, which can realize rapid measurement of direct resistance.
