Description:
100% brand new,high quality
The internal circuit adopts surface mount technology, which greatly improves the anti-interference and service life of the instrument. The display interface adopts a 2.4-inch TFT liquid crystal display with 320*240 high resolution, which can display all the parameters of the channel and prompt the current button functions, effectively utilize the button resources, and avoid frequent user button operations, greatly enhancing the display interface. Operability. It is an ideal test and measurement equipment for electronic engineers, electronic laboratories, production lines and teaching and research.
