Introduction
The ZXHL-100A circuit resistance tester is designed according to the People's Republic of China Electric Power executive standard DL/T845.4-2004, using the combination of high frequency switching power supply technology and digital circuit technology. It is suitable for measuring circuit resistance of switching control equipment. The test current adopts the DC 100A recommended by the national standard. 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, and meets the requirements of on-site maintenance of high-voltage switch in power supply department and circuit resistance test in high-voltage switch factory.
Product Features
1. High current: The use of new 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 last data of the LCD screen can be stabilized within the range of ±1 word, with stable reading and good repeatability.
3. Long service life: All high-precision resistors are used to effectively eliminate the impact of ambient temperature on the measurement results, and the use of connectors enhances the anti-vibration performance.
4. Easy to carry: small size, light weight.

1. High current: For latest power supply technology, the tester can continuously output high current which overcomes the weakness of instantaneous current produced by pulsed power. It can effectively breakdown/puncture the oxide layer of the switches and then get precise results.
2. Strong anti-interference ability: The last number of test data will stably show in the LCD screen only with ±1 error even in strong Interference situation.
3. Long service life: all high-precision resistors are used to effectively eliminate the influence of ambient temperature on the measurement results. At the same time, the use of connectors enhances the anti vibration performance.
4. Convenience: Small size, light weight.
