GDHL-200A Circuit Breaker Contact Resistance Tester 
  I.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.
