1, High Current: Using the latest switching power supply control technology, it can continuously output high current for a long time, overcoming the drawbacks of instantaneous current in pulse-type power supplies. It can effectively break through the oxide film on switch contacts, resulting in good test analysis results.
2, High Stability: Under severe interference, the last digit of the LCD reading can remain stable within ±1 digit, ensuring stable readings and good repeatability.
3, High Accuracy: Dual high-speed 16-bit Σ-Δ AD sampling, combined with the latest digital signal processing technology, achieves the highest resolution of 0.01μΩ. It is currently the only method to achieve 0.01μΩ resolution and very stable contact resistance measurement, with performance exceeding imported high-current micro-ohmmeters.
4, Intelligent: Equipped with an imported high-performance CPU, the system can automatically switch ranges based on signal strength during measurement, ensuring test accuracy. The over-temperature protection circuit design automatically stops current output when the instrument exceeds a set temperature, ensuring safe and reliable operation.
5, High Quality: Key components are imported, and a cleverly designed temperature compensation circuit effectively eliminates the influence of ambient temperature on measurement results. Military-grade connectors enhance vibration resistance.
6, Powerful: With a current of 50A or optional 100A, the test time can be set arbitrarily from 5 seconds to 599 seconds, overcoming the shortcomings of other similar instruments that cannot set measurement time or have too short continuous operation times, far exceeding the performance of other similar devices.
7, User-Friendly Interface: The rotary mouse allows for convenient and quick data input, and the instrument can automatically set the date and time, save measurement data in real-time, and print measurement results instantly.
8, USB Transfer: Measurement data can be transferred to a USB drive via the USB interface, and combined with host computer software for further analysis and processing, making it convenient to use.
9, Compact and Lightweight: Small size, light weight, and easy to carry.
As a very common high-voltage electrical test device, the loop resistance tester is frequently used in work. Therefore, it is essential to be familiar with its working principle, test methods, and characteristics.
