通过Python/cmd下的 meterrec完成实验台面万用表数据自动记录的功能。

■ 命令

1.命令格式

• meterrec ch dn
  记录单通道，并最终拷贝到CLLIPBOARD。

• meterrec ch dn #tab1 tab2 tab3…
  记录单通道，并根据tab1,2,3自动粘贴到 CSDN 形成表格
  如果第一个参数以‘#’’开始，则最开始为序号

• meterrec datafile ch1 ch2 ch3…
  记录多通道到数据文件。

2.通道定义

• 0~3: 桌面万用表集成测量通道数据

• 4：DM3068：VDC

• 5：DM3068：VAC

• 6：DM3068：RES

• 7：DM3068：FREQ
  

  ^{▲ 台面万用表数据通道}

3.鼠标操作

Ⅰ.鼠标左键 ：记录一条记录。

Ⅱ.鼠标右键：在第一种命令下，开启新的记录行；在第2,3种记录命令，将当前记录清零。

Ⅲ.左键–>右键：在第一种命令下，将MSG窗口内容拷贝到CLIPBOARD，并清楚。在第二种命令下，还包括自动粘贴；第三种命令没有特殊功能。

Ⅳ.右键–>左键：退出程序。退出后，MSG窗口内的拷贝到CLIPBOARD。
