Performance Features of Intelligent Loop Resistance Tester:
Large Current: The intelligent loop resistance tester uses the latest switching power supply technology, capable of continuously outputting large current for extended periods, overcoming the drawbacks of instantaneous current from pulse power supplies. It effectively breaks through the oxide film on switch contacts, yielding excellent test results.
High Stability: Under severe interference conditions, the last digit of the LCD reading remains stable within ±1 digit, ensuring stable readings and good repeatability.
High Precision: Utilizing dual-channel high-speed 16-bit Σ－Δ AD sampling and the latest 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, outperforming imported high-current micro-ohmmeters.
Intelligent: Equipped with an imported high-performance CPU, the system automatically switches measurement 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 operation.
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.
Powerful Functions: The current can be freely selected between 50A and 100A, and the 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 operation periods, far exceeding the performance of other similar devices.
User-Friendly Interface: Data input via a rotary mouse is convenient and quick. Users can set the instrument's date and time, save measurement data in real-time, and print measurement results instantly.
Multiple Communication Methods: It can communicate with a computer via RS232 serial port (9-pin) or USB data cable, uploading measurement data to the computer for further analysis by test personnel.
