1 General introduction
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.
