Product Details
1. Product Name:
Contact resistance tester HYHL-200A
2. Equipment Description:
100A and 200A are same panel design.
Contact resistance tester output DC 200A/100A current to test the
contact resistance of circuit breaker or high current cable
contacts. It is designed according to IEC62271. The main
application of the tester is measurement of circuit breaker contact
resistance. All the test results of the tester could be print by
the micro-printer which is integrated in the tester. Also all the
test results saved in the tester could be upload to PC computer and
then convert to MS WORD document.

5. Product Panel:
The low resistance tester is shown as figure 1. The tester output
100A DC current to sample from tester connection terminal when
testing. The current value and voltage value between sample
terminals are sampled by the tester from connection terminals. The
value is shown on the LCD is the resistance measured and the unit
of the value is uohm.
