100A 200A contact resistance meter micro ohm tester
I.Brief Introduction Circuit Breaker Contact Resistance Tester is mainly used for measuring contact resistance and loop resistance of switching control equipment, designed with High frequency switching power supply technology and digital circuit technology combined . The loop resistance can be directly measured at the current of 100A and 200A. The test results displayed on large LCD screen, with functions of data storage, output printing, time setting , etc .
The contact resistance of switchgear increases due to the oxidation of contact surface and poor contact fastening, etc. In the case of large current flow, the temperature of contact point rises, which accelerates the oxidation of contact surface and further increases the contact resistance. If it continues, serious accidents will occur. Therefore, it is necessary to measure the contact resistance regularly with loop resistance tester .
II. Main Features 1.Available to output large current continuously , effectively breakdown oxidation film on switch contact. 2.Even under severe interference condition, the last bit of data can be stable within ±1 word . 3.With highest resolution of 0.01 mu Ω. 4.The measure system automatically switches the measuring range according to the signal due to its High-Performance CPU design, then possible to ensure the accuracy of test result .And temperature protection circuit can automatically stop the output current when the instrument exceeds the setting temperature. 5.Temperature compensation circuit design can effectively eliminate the influence of ambient temperature on measurement results. 6.The current can be freely selected from 50A, 100A, 150A and 200A, and the test time can be arbitrarily set within 5S-59. 7.Friendly human-machine interface. The date and time can be set independently, the measurement data can be saved in real time, and the measurement results can be print out . 8.It can communicate with computer through RS232 serial port (9 pins) or USB cable, and upload data into computer Hot tags : Loop Circuit Resistance Tester, contact resistance tester, digital mirco ohm meter
