The circuit resistance can be measured directly at the current of 100A and displayed digitally. The instrument is accurate in measurement and stable in performance. It meets the requirements of on-site maintenance of high-voltage switch in power supply department and circuit resistance test in high-voltage switch factory.

1. High current: The use of the latest power supply technology, can be a long time continuous output of large current, to overcome the drawbacks of pulsed power supply instantaneous current, can effectively breakdown the switch contact oxide film, get good test results.
2. Strong anti-interference ability: under severe interference conditions, the LCD screen can be stabilized within the range of ±1 word, with stable reading and good repeatability.
3. Long service life: the use of high-precision resistance, effectively eliminate the impact of ambient temperature on the measurement results, while the use of military connectors to enhance the anti-vibration performance.
4. Easy to carry: small size, light weight.
