Ground wire group DC resistance tester provided by Yangzhou Topu Electric Technology Co., Ltd. Technical parameters

The grounding wire group DC resistance tester is a highly automated portable tester specifically designed to measure the DC resistance of portable short-circuit grounding wires and personal protective grounding wires. The instrument adopts high-performance microcontroller control, which can achieve intelligent testing process, simple and convenient operation, high accuracy, fast testing speed, good repeatability, and intuitive reading. It is an ideal specialized instrument that meets the requirements of regulations, greatly facilitating the development of experimental projects and improving work efficiency. The newly issued "Preventive Test Regulations for Electric Power Safety Tools" require regular DC resistance tests to be conducted on portable short-circuit grounding wires and personal protective grounding wires.

Product Features

The grounding downlead continuity tester uses the basic calculation formula R=U/I for DC circuits and the principle that the current in the series circuit is equal everywhere. It adopts the four terminal method measurement principle, and the high current constant current output effectively eliminates the influence of the test line resistance on the test results.
