1. High Current: The high-precision loop resistance tester uses power supply technology to continuously output high current for a long time, overcoming the drawbacks of instantaneous current from pulse power supplies. It can effectively break through the oxide film on switch contacts, yielding good test results.
2. High Stability: Under severe interference conditions, the last digit of the LCD reading can remain stable within ±1 digit, ensuring stable readings and good repeatability.
3. High Precision: Utilizing dual-channel high-speed 16-bit Σ-Δ AD sampling and digital signal processing technology, the maximum resolution reaches 0.01μΩ. It is currently the only contact resistance tester in China that achieves 0.01μΩ resolution with high stability, surpassing the performance of imported high-current micro-ohmmeters.
Performance exceeds imported high-current micro-ohmmeters.
4. Intelligent: Equipped with 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 current output when the instrument exceeds the set temperature, ensuring safe use.
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 Functionality: Current can be freely selected among 50A, 100A, 150A, and 200A, and test time can be set arbitrarily from 5s to 599s, overcoming the shortcomings of other similar instruments that cannot set measurement time or have insufficient continuous working time, far exceeding the performance of other similar instruments.
