brief introduction
This DC low resistance tester is specifically designed to test various resistors. With a touch function, a 24 bit 4.3 inch color LCD screen is easy to operate and has fast testing speed. It is suitable for various resistance design, inspection, quality control, and production testing. This machine has an additional three speed sorting function. When sorting, you can choose to display the resistance value or percentage ratio, and you can judge whether the resistance value is too large, too small, or good based on the set value. There is also a sorting interface on the back panel of the instrument, which enables the interface to activate signals for measurement. The test results are also output by the interface on the back panel. Through this signal interface, the instrument can be connected to component mechanical processing equipment for automatic testing. In addition, this machine has a USB interface and a Handler port, and the panel function can be completely controlled by the computer. Test results can also be sent back to the computer for storage through the USB interface or USB interface, or data can be directly saved in a USB drive.
