Features of Switch Contact Resistance Tester:
l Adopting the latest power supply technology, it can continuously output large current for a long time, and flexibly select four current gears: 50A, 100A, 150A, and 200A.
l This instrument has the characteristics of small size, light weight, strong anti-interference ability, high precision, convenient operation, and complete protection functions.
l It uses a precision instrumentation operational amplifier and a high-precision quadruple integration A/D converter, combined with a high-performance 16-bit single-chip microcomputer. During measurement, the system automatically switches the amplification factor according to the signal size, ensuring the test accuracy of this product.
l The human-machine dialogue adopts full keyboard operation mode, with intelligent working process throughout.
l 320×240 LCD display, high-speed thermal printer.
l This product also designs a real-time calendar clock, providing time basis for printing and saving data.
l Data storage and historical data browsing functions, can store 200 sets of data, and has power-off protection function.
l Ultra-wide range, the maximum measurement range reaches 0-4mΩ.
