Performance Features of Intelligent Loop Resistance Tester:The intelligent loop resistance tester provides high current: utilizing the latest switching power supply technology, it can continuously output high current for extended periods, overcoming the drawbacks of instantaneous current from pulse-type power supplies, effectively breaking through the oxide film on switch contacts to achieve excellent test results.
High stability: under severe interference conditions, the last digit on the LCD screen can remain stable within ±1 digit, ensuring stable readings and good repeatability.
High precision: employing dual high-speed 16-bit Σ－Δ AD sampling and the latest digital signal processing technology, the maximum resolution reaches 0.01μΩ, making it the only contact resistance tester in China that can achieve 0.01μΩ resolution with high stability, outperforming imported high-current micro-ohmmeters.
Intelligent: equipped with a high-performance imported 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, enhancing vibration resistance.
Powerful functions: current can be freely selected between 50A and 100A, 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 operation time, far surpassing the performance of other similar devices.
User-friendly interface: data input via a rotary mouse is convenient and quick, allowing users to set the instrument's date and time, save measurement data in real-time, and print measurement results immediately.
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 and processing by test personnel.
(9) Easy to use: compact size, light weight, and portable.
