 Loop resistance tester another name: 
 Contact resistance tester, switch loop resistance tester, contact loop resistance tester, contact (circuit) resistance tester 

 Loop Resistance Tester Description: 
 ETHL-200A high-voltage switch loop resistance tester is based on the latest People's Republic of power performance standards DL/T845.4-2004, using high-frequency switching power supply technology and digital circuit technology designed by the combination. It is suitable for switching control loop resistance measurement devices. The test current national standards recommended by the DC 100A and 200A. 100A in the current situation can be directly measured loop resistance can also be the case in the current of 200A circuit resistance measured directly, but with 200A current test, the test of time prohibited more than 2 minutes to ensure the safe operation of power! Last The test results are shown with figures. The instrument measurement accuracy, stable performance, with the power, the electricity sector on-site maintenance and high voltage switch high voltage switch factory loop resistance testing requirements. 


 Loop resistance tester features: 
 (1) high-current: using the latest power supply technology to a long continuous output high current pulse to overcome the shortcomings of the power transient current can effectively switch contact oxide film breakdown, get good results. 
 (2) anti-jamming: the serious interference conditions, the LCD screen can be stabilized at the last data word within ± 1, the reading is stable and repeatable. 
 (3) Long life: all use high-precision resistor, effectively eliminate the environmental impact of temperature on the measurement results, while enhancing the use of military connectors vibration resistance. 
 (4) easy to carry: small size, light weight.
