Products introduction
This product overcomes the disadvantage of traditional circuit resistance measuring instruments that require adjusting the current output; The large screen graphic LCD with wide temperature band backlight is adopted instead of the traditional Nixie tube display mode, which can display Chinese characters intuitively, making the operation of the instrument more convenient and simple. This product uses a precision instrument operational amplifier and a high-precision A/D converter, combined with a high-performance 16 bit microcontroller, to ensure the testing accuracy of the product;
This product has also designed functions such as real-time calendar clock, data storage, printing and protection, which makes the product more complete and cost-effective.
