According to the requirements of the new "Regulations for Handover and Preventive Tests of Power Equipment", the test current for measuring the conductive circuit resistance of various switchgear shall not be less than 100A. In response, our factory has designed and developed a new generation of intelligent circuit resistance tester products according to the new regulations. This product is suitable for testing the contact resistance of main contacts in high and low voltage switches, as well as the DC resistance of high and low voltage cable lines. The JD-100 A intelligent circuit resistance tester adopts a 100A constant current output. The maximum output voltage reaches 10V (2-3 times that of conventional instruments), allowing the use of thin test leads, which greatly reduces the labor intensity of field test personnel. The entire testing process is automatically controlled by a microcontroller, offering high precision and good repeatability. It features single-button operation, is simple and easy to use, displays test data on an LCD, and prints results. It is suitable for various working environments.
