Product Introduction:
contact loop resistance testeroperator panel is ergonomically designed to meet operational habits and uses high frequency switching power supplies and digital circuit technology for the measurement of loop resistance in switch control equipment. The test current is DC 100A recommended by the national standard. The loop resistance can be directly measured under the condition of DC 100A. The test result is displayed by large-screen LCD LCD and has functions of data storage output printing time setting etc. and 50A gear position for users to choose; custom test time maximum The set time is 599S which is much larger than the standard 60S. It is a very stable contact resistance tester with a resolution of 0.01µO in China. The performance exceeds the imported high current micro-ohmmeter. It meets the requirements of on-site high-voltage switch maintenance and high-voltage switch factory loop resistance test in electric power and power supply departments.

Product Characteristics:
1. Powerful function: The current is freely selected in 50A and 100A. The test time is set arbitrarily within 5s~599s. Overcoming the defects that other similar instruments cannot set the measurement time or the continuous working time is too short far exceeds the other similar instruments. performance.
2. Friendly man-machine interface: Rotate the mouse to input data which is convenient and quick. Set the date and time of the instrument independently save the measurement data in real time and print the measurement result in real time.
3. USB transfer: The measurement data is transferred to the U disk through the USB interface and the measurement data is further analyzed and processed in combination with the host computer software.
