Product introduction

Used for a variety of high voltage circuit breakers (referred to as switch) main contact contact resistance measurements, you canalsotest the highvoltage 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 therelevantregulations, can be a longstable 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 thestate. Usingthe new power and precisionmeasurement and control circuits combined, making the measurement data with high accuracy and good reproducibility.

Also called?name

Loop resistance tester, contact resistance tester, switch loop resistance tester, the contact loop resistance tester, touch(loop)resistancetester

The Characteristics of the products

1. large electric current: Using the latest Power technology to a long continuous output high current pulsed power to overcomethedrawbacks of theinstantaneous 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 ±1digit range, the reading is stableand repeatable.

4. long life: all precision resistors, the effective elimination of ambient temperature on measurement results, while enhancing theuseof militaryconnectors vibration resistance.

5. Easy to carry: small size, light weight.
