KEHLY-A Model  Fully Automatic Loop Resistance Tester

I. Purpose and Features of the Instrument
       According to the new "Handover and Preventive Test Regulations for Power Equipment," the measurement of conductive loop resistance for various switching devices requires a test current of no less than 100A. In response, our company has designed and developed a new generation product: the KEHLY-A Fully Automatic Loop Resistance Tester. This product is suitable for testing the contact resistance of main contacts in high and low voltage switches, the DC resistance of high and low voltage cable lines, and more.
       The KEHLY-A Fully Automatic Loop Resistance Tester adopts a 100A constant current output. With a test voltage of up to 10V, it allows the use of thinner test leads, significantly reducing the workload for field test personnel. The entire testing process is automatically controlled by a single-chip microcomputer, with adjustable test duration, high precision, excellent repeatability, simplicity, and ease of operation. Test data are displayed on an LCD screen and can be printed.
