Switch Loop Resistance Tester - Yangzhou Darui
Darui Electric recommends for you
Product Features:
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 in 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 screen 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 0.01 μΩ. It is currently the only contact resistance tester in China that achieves 0.01 μΩ resolution with high stability, surpassing imported high-current micro-ohmmeters in performance.
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 output current 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 connectors enhances vibration resistance.
6. Powerful Functions: 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 short continuous working times, far exceeding the performance of other similar instruments.
7. User-Friendly Interface: Data input via a rotary mouse is convenient and fast. Users can set the instrument date and time, save measurement data in real-time, and print measurement results instantly.Switch Loop Resistance Tester
Transportation and Storage:
1. Transportation
When the equipment needs to be transported, it is recommended to use our company's instrument packaging wooden case and shock-absorbing materials to avoid unnecessary damage during transit and prevent unnecessary losses.
When the equipment is transported without a wooden case, stacking is not allowed. When using our company's instrument packaging case, the maximum stacking layers allowed is two.
During transportation, the instrument panel should face upward.
2. Storage
The equipment should be placed in a dry, dust-free, ventilated indoor environment free of corrosive gases. Without wooden case packaging, stacking is not allowed.
When storing the equipment, the panel should face upward. Place moisture-proof items at the bottom to prevent dampness.
