Product Description
LNL-200A Electronic Contact Resistance Tester 220V Secondary Injection Relay for Test
LNL-200A Electronic Contact Resistance Tester 220V Secondary Injection Relay for Test
The operation panel of this instrument adopts an ergonomic design that conforms to operating habits. It adopts high-frequency switching power supply and digital circuit technology, and is suitable for measuring the circuit resistance of switch control equipment. The testing current adopts the DC 200A recommended by the national standard. The circuit resistance can be directly measured under DC 200A, and the test results are displayed on a large LCD TFT color screen, with functions such as data storage, output printing, and time setting. There are 50A, 100A, 150A, and 200A gears for users to choose from; Customized testing time, with a maximum set time of 60S, it is a very stable contact resistance tester with performance exceeding that of imported high current micro ohmmeters. Meet the requirements of on-site high-voltage switch maintenance and high-voltage switch factory circuit resistance testing by the power and power supply departments.
