According to the requirements of power equipment preventive test rules, the test of
contact resistance of various switchgear is one of the conventional test items. The tester
outputs DC constant current of 100A and 200A. The tester has the advantages of simple
operation interface, high precision, strong anti-interference ability, good repeatability,
small main body size, light weight and easy to carry. The tester has a
thermal micro printer, which is convenient to print the current test results and is practical.
