1. High Current: Utilizing the latest switching power supply technology, it can continuously output high current for a long time, overcoming the drawback of instantaneous current in pulse power supplies, effectively breaking through the oxide film on switch contacts, and yielding good test results.

  2. High Stability: Under severe interference conditions, the last digit of the LCD screen can stabilize within ±1 digit, ensuring stable readings and good repeatability.

  3. High Precision: Employing dual-channel high-speed 16-bit Σ－ΔAD sampling and the latest digital signal processing technology, the maximum resolution reaches 0.01μΩ, making it currently the only contact resistance tester in China that achieves 0.01μΩ resolution with high stability, outperforming imported high-current micro-ohmmeters.

  4. Intelligent: Using an imported high-performance CPU, the system automatically switches ranges based on signal strength during measurement, ensuring test accuracy. The over-temperature protection circuit automatically stops output current when the instrument exceeds the set temperature, ensuring safe usage.

  5. High Quality: All key components are imported, and a cleverly designed temperature compensation circuit effectively eliminates the influence of ambient temperature on measurement results. The use of military-grade connectors enhances vibration resistance.

  6. Powerful Functions: Current can be freely selected among 50A, 100A, 150A, and 200A, and test time can be set arbitrarily from 5s to 599s, overcoming the limitations of similar instruments that cannot set measurement time or have short continuous working periods, far exceeding the performance of other similar devices.

  7. User-Friendly Interface: Data input via a rotary mouse is convenient and fast, allowing users to set the instrument's date and time, save measurement data in real-time, and print results immediately.

  8. Multiple Communication Methods: It can communicate with a computer via RS232 serial port (9-pin) or USB data cable to upload measurement data for further analysis by test personnel. Easy to use: compact size, light weight, and portable.
