Product introduction
Used for a variety of high voltage circuit breakers (referred to as switch) main contact contact resistance measurements, you can also test the high voltage cable lines, busbars, weld and any low resistance non-inductive electrical resistance values, etc.
Accordance with the latest standards "JJG1052-2009 loop resistance test procedures" GB50150-91 and DL/T596-1996 the relevant regulations, can be a long stable output of not less than 100A large current, the instrument can not be avoided continuous work and thus can not effectively breakdown "oxide film" of the state. Using the new power and precision measurement and control circuits combined, making the measurement data with high accuracy and good reproducibility.
Alternative name
Loop resistance tester, contact resistance tester, switch loop resistance tester, the contact loop resistance tester, touch (loop) resistance tester
The Characteristics of the products
1. large electric current: Using the latest Power technology to a long continuous output high current pulsed power to overcome the drawbacks of the instantaneous current can effectively switch contacts oxide film breakdown, get good test results.
2. anti-interference ability: In severe interference conditions, the LCD screen can be stabilized at last a data ± 1 digit range, the reading is stable and repeatable.
4. long life: all precision resistors, the effective elimination of ambient temperature on measurement results, while enhancing the use of military connectors vibration resistance.
5. Easy to carry: small size, light weight.
