The measuring instrument for DC resistance is a project for semi-finished and finished products in the manufacturing of inductive coils such as transformers, transformers, reactors, and electromagnetic operating mechanisms, as well as for factory testing, installation, handover testing, and preventive testing by the power department. It can effectively detect manufacturing defects such as material selection, welding, loose connection parts, missing strands, and broken wires of inductive coils, as well as hidden dangers after operation.

In order to meet the needs of rapid measurement of DC resistance in inductive coils, our company has developed the KDZR-10A DC resistance measuring instrument using our own technological advantages. This instrument adopts new power technology and has the characteristics of small size, light weight, large output current, wide range, digital display, and internal lithium battery power supply. The whole machine is controlled by a microcontroller, which automatically completes self checking, data processing, display and other functions, and has automatic discharge and discharge indication functions. The instrument has high testing accuracy, easy operation, and can achieve rapid measurement of direct resistance.
