The circuit resistance tester under UHV power can help many power workers conduct various power tests more conveniently.
1、 High current
The circuit resistance tester adopts the latest switching power supply technology, which can continuously output high current for a long time, overcoming the disadvantage of high instantaneous current of pulse power supply, effectively breaking the oxide film of switch contacts, and obtaining good test results.
2、 High stability
In the case of severe interference, the final data of the LCD can remain stable within ± 1 word range, with stable readings and good repeatability.
3、 High precision
The circuit resistance tester adopts bidirectional high-speed 16 bit sigma delta AD sampling and the latest digital signal processing technology, with a maximum resolution of 0.01 μ Ω. At present, it is a very stable contact resistance tester in China that can achieve a resolution of 0.01 μ Ω, and its performance exceeds that of imported high current micro ohmmeters.
4、 Long service life
The circuit resistance tester uses high-precision resistors. Through the clever design of temperature compensation circuits, the influence of environmental temperature on measurement results can be effectively eliminated. Meanwhile, the use of military connectors enhances the anti vibration performance.
5、 Intelligent
The circuit resistance tester adopts imported high-performance CPU, and the system automatically switches the range according to the signal size to ensure the testing accuracy of the product. The over temperature protection circuit can automatically stop outputting current when the instrument exceeds the set temperature, ensuring the safe use of the instrument.
6、 Powerful
The current of 50A and 100A can be freely selected, and the testing time can be set arbitrarily from 5s to 599s, overcoming the shortcomings of other similar instruments that cannot set the measurement time or the continuous working time is too short, far exceeding the performance of other similar instruments.
7、 Friendly human-machine interface
Input data conveniently and quickly by rotating the mouse. You can set the date and time of the instrument, save measurement data in real-time, and print measurement results in real-time.
8、 Multiple communication methods
It can communicate with a computer through RS232 serial port (9-pin) or USB data cable to upload measurement data to the computer for further analysis and processing by the tester.
9、 Use attributes
The circuit resistance tester is small in size, light in weight, and easy to carry.
