摘要
UC70D万用表除了具有普通万用表的特点外,在测量精度方面也比较高,并且具有RS232接口,便于应用在测量领域。本设计解析了UC70D万用表的传送命令,并给出了与MCS51单片机连接的硬件原理图和部分程序,该设计在系统中运行良好。
Not only multimeter is the characteristic of normal multimeter, but also it is very good on measure precision, there is the RS232 interface, it is good at measure field. The design parses the transmittal command of the UC70D multimeter, also set out the hardware theory chart and a part of programs ,The design is very good on the system.
