Product Details

 Introduction to Switch Loop Resistance Tester:

  The loop resistance tester is a specialized instrument used for measuring contact resistance and loop resistance of switch control equipment. The test current adopts the 100A DC recommended by the national standard GB763. It can directly measure loop resistance or contact resistance at currents of 100A, 200A, 300A, 400A, 500A, or 600A, and display the results directly. It can also save up to 100 groups of data on the instrument. The saved data can be communicated with the upper computer via the RS232 interface, uploaded to the computer for storage or printing. This instrument features accurate measurement and stable performance, suitable for on-site high-voltage switch maintenance in power and power supply departments, as well as for loop resistance testing requirements in high-voltage switch factories.
