Postato il 02/03/2023 : 03:00:39https://www.mktester.com/hv-switch-tester/contact-loop-resistance-tester.htmlProduct Introduction#65306; 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 0.01#956;#937; 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.
