Profile:

KDHL-100A operating panel adopts ergonomic design, in line with operation habits, adopts high frequency switching power supply and digital circuit technology, which is suitable for the measurement of circuit resistance of switching control equipment

Features:

1. High current: The new switching power supply technology can continuously output large current for a long time, overcoming the drawbacks of the instantaneous current of the pulse power supply, and can effectively break down the oxide film of the switch contacts and obtain good test results.
2. High stability: under severe interference conditions, the last data of the LCD screen can be stabilized within the range of ±1 word, with stable reading and good repeatability.
3. High precision: The use of dual-channel high-speed 16-bit Σ-ΔAD sampling, digital signal processing technology, the highest resolution of 0.01μΩ, is currently able to reach 0.01μΩ resolution and very stable contact resistance tester
4. Intelligent: When measuring, the system automatically switches the range according to the signal size to ensure the test accuracy of the product. The overtemperature protection circuit can automatically stop the output current when the instrument exceeds the set temperature to ensure the safe use of the instrument.
5. High quality: Through the ingenious design of the temperature compensation circuit effectively eliminate the impact of ambient temperature on the measurement results, the use of military connectors enhances the anti-vibration performance.
6. Powerful function: the current can be freely selected in 50A, 100A, and the test time can be set within 5s~599s, overcoming the defect that the measurement time can not be set or the continuous working time is too short, and the performance is good.
7. Friendly man-machine interface: by rotating the mouse to input data, convenient and fast, you can set the instrument date and time, save the measurement data in real time, and print the measurement results in real time.
8.USB transfer: The measurement data can be transferred to the U disk through the USB interface, and the measurement data can be further analyzed and processed with the upper computer software.
