100A loop resistance tester is applicable to the high-accuracy measurement of high-voltage switch contact resistance (loop resistance), as well as other scenarios requiring large current and micro resistance measurement.
The 100A loop resistance tester is designed by incorporating the high-frequency switch power technology and the digital circuit technology in accordance with the latest China power executive standard DL/T845.4-2004. It is applicable to the measurement of the switch control equipment loop resistance. The testing current applies DC 100A as stated in the national standard. The loop resistance could be measured directly under the current 100A and displayed in number. The product is accurate in measurement and stable in performance, conformable to the requirements for field high-voltage switch maintenance and high-voltage switch plant loop resistance testing of power and power supply sectors.

1. Large current: The product applies the new power technology, capable to output large current in continuous way for long time, overcoming the disadvantage of impulse type power transient current, capable to breakdown the oxide film on the switch contact and achieve good testing results.
2. Strong interference resistant capability: Under severe interference condition, the last digital on the LCD could maintain within ±1 digit, with stable reading and good repeatability.
3. Long service life: The application of high-accuracy resistance eliminates the influence of environment temperature to the measurement results. The application of military connector increases the damping property.
4. Portable: Small volume, light weight.
