For example, the DAQ board has an analog channel ao0. In the program, I want to read and record the voltage of ao0 first. When the program is done, I can set the channel back to the original voltage.
What you can do is connect the analog output channel to one of your analog input channels and then read and graph the value. If you do not want to physically wire the two channels together here is a KnowledgeBase which will show you how to read the analog output channel by comparing it to the analog output ground: Read the Value of Analog or Digital Output Channels. This method is not as precise, so I still recommend physically wiring the analog output to an analog input. Please let me know if you have any questions.
