摘要
本文论述了基于仪表放大器AD620和6脚P IC单片机的指针检流计的设计。解决了目前指针检流计容易出现漂移的问题。采用2节5号电池供电并利用单片机进行功耗管理,有效地降低了检流计的电池使用成本。
Finger galvanometer design based on instrumentation amplifier AD620 and 6 Pin PIC mcu was introduced in this paper.The excursion problem of current finger galvanometer was solved.Powered by two AA batteries and use MCU to manage the power consumption,can effectively lower the cost of battery consumption of the galvanometer.
