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 a long time, overcoming the drawbacks of instantaneous current from pulse power supplies, effectively breaking through the oxide film on switch contacts, and obtaining good test results.
High Stability: Under severe interference conditions, the last digit of the LCD screen can remain stable within ±1 digit, with stable readings and good repeatability.
High Precision: Using dual-channel high-speed 16-bit Σ－Δ AD sampling and the latest digital signal processing technology, the highest 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: Using an imported high-performance CPU, the system automatically switches ranges based on signal strength during measurement, ensuring the accuracy of the product. The over-temperature protection circuit automatically stops current output when the instrument exceeds the set temperature, ensuring safe use.
High Quality: All key components are imported, and the 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 shortcomings of other similar instruments that cannot set measurement time or have short continuous working times, far exceeding the performance of other similar instruments.
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 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 by test personnel.
(9) Easy to Use: Small size, light weight, and portable.
