HL100 Contact Resistance Tester with printer


Resistance Measurement



INTRODUCTION

The risk of overheating is becoming more serious due to the fact that today’s distribution networks have to carry heavier loads. Checking contact resistance at regular intervals detects faults before they cause overheating. Contact resistance tester is used to measure contact resistances of circuit breakers, disconnecting switches, earthing switches, bus joints, bushing contact joints and welding joints. Also for any low resistance measuring application. The tester provide 100A DC current, and the voltage measurement gets the voltage of tested object.The method of calculate resistance according to Ohm's law. (R=U/I)
 
FEATURES

l Setting current output time between 1s to 60s.
l Save the device’s series number, for checking the result conveniently.
l Display output current,output time and resistance during testing.
l Saving 100 test results in tester memory.
l Built-in clock record the date.
l The stored result includes device’s number, testing time and resistance.
l The tester equiped with micro-printer.
