Nickname: Contact Resistance Test; Loop tester
Feature:
1.High current: It adopts new switching power supply technology, which can continuously output large current for a long time, overcomes the shortcomings of the instantaneous current of pulsed power supply, can effectively penetrate the switch contact oxide film and obtain good test results.
2.High stability: under severe interference conditions, the last data of the LCD screen can be stable within ±1 word range, the reading is stable and the repeatability is good.
3.High precision: using dual high-speed 16-bit Σ-Δ AD sampling, digital signal processing technology, the highest resolution reaches 0.01μΩ, is currently a very stable contact resistance tester with a resolution of 0.01μΩ in China, the performance exceeds Imported high current micro-ohmmeter.
4.Intelligent: High-performance CPU of the port. When measuring, the system automatically switches the range according to the signal size to ensure the test accuracy. The over-temperature 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: All key components are imported components. The ingeniously designed temperature compensation circuit effectively eliminates the influence of ambient temperature on the measurement results. The use of military connectors enhances the anti-vibration performance.
6.Powerful function: The current is freely selected in 50A and 100A. The test time is set arbitrarily within 5s~599s. Overcoming the defects that other similar instruments cannot set the measurement time or the continuous working time is too short, far exceeds the other similar instruments. performance.
7.Friendly man-machine interface: Rotate the mouse to input data, which is convenient and quick. Set the date and time of the instrument independently, save the measurement data in real time, and print the measurement result in real time.
8.USB transfer: The measurement data is transferred to the U disk through the USB interface, and the measurement data is further analyzed and processed in combination with the host computer software.
9.Easy to use: small size, light weight, easy to carry.
