Brief description

The equipment is suitable for measuring loop resistance/contact resistance of switching control device. It can directly measure the loop resistance under 3 current scales of 50A/100A/200A with digital display and it can print the test result. The instrument has the characters of good accuracy, performance and stability. It can meet the requirements of power sector field and high-voltage switch factory to test loop resistance/contact resistance.
