Use characteristics

According to the new "power equipment transfer and preventive test procedures" requirements, a variety of switching equipment, conductive circuit resistance measurement, the test current shall not be less than 100A. I plant according to the new requirements of the design and development of a new generation of intelligent loop resistance tester products , The product is suitable for testing the main contact contact resistance of high and low voltage switch, high and low voltage cable line DC resistance, etc. JHZHL loop resistance tester with 100A constant current output. The maximum output voltage of 10V can be used with fine surface test Line, greatly reducing the labor intensity of the field test staff.The test process is fully implemented by the single-chip control, high precision, re-test is good, simple, test data LCD display, the results of the test time in accordance with national standards 15S; 30S ; 60S adjustable, eliminating the rapid test of the test product, the surface oxide resistance resistance, so that greatly improve the accuracy for different working conditions.
