The equipment is suitable for switching control device loop resistance measurement. The test current of National Standards recommended by the DC 100A. It can directly measure the loop resistance under current of 100A and show the result with digital display. The instrument has the characters of measurement accuracy, performance and stability. It can meet the requirements of power sector field and high-voltage switch factory to test loop resistance. There are 100A and 200A for option.
Features:
(1) Heavy current: It uses the newest technolegy of Power Sources to output large current for long time, it overcomes problems of the pulse type power source instantaneous electric current. It might obtain the good test result.
(2Good antijamming ability: Under the serious disturbed condition,the last figure can stabilize ±1 character scope on the liquid crystal screen , and the reading is stable.
(3) Long life service: Uses the high accuracy resistance completely, and effectivly eliminates the the influence of ambient temperature,simultaneously the military goods connector's use strengthen the vibration-proof performance.
(4) Portability: there is a small size and light weight.
