Can the contact resistance tester measure the resistance?
Loop resistance tester adopts a large screen LCD backlight display and wide temperature, not the traditional digital tube or liquid crystal display meter, Chinese characters directly, make the instrument operation more convenient and simple;
Switch contact resistance tester using precision operational amplifier and high precision A/D converter with high performance sixteen bit microcontroller, when measuring the magnification of the system according to the signal magnitude of automatic switching, to ensure that the product testing accuracy;
The loop resistance tester uses a DC constant current source with high accuracy and high stability. It can provide fixed DC current output of 100A or 200A. It overcomes the shortcoming of the traditional high precision loop resistance tester to adjust the current output;
