How to save a analog signal and open it as a waveform?

[Julye]

I am a new for labVIEW programming. I did a little program to take out voltage signal from loadcell, and try to save it into a file and be able to display waveform when open it.But it doesn't work. Is there any one here give me some advice? I would be very appreciate.

How exactly did you save it and how did your try to open it? Simply saying that it doesn't work, is not much information. How doesn't it work the way you expect?

There are some basic functions in LabVIEW that should make this pretty simple. For example, the Express VIs Write to Measurement File and Read From Measurement File.

You could attach the VIs you wrote to write and read the file and someone could look at them to see what might be incorrect.

Hi Julye,

Welcome to programming with LabVIEW! To get started, you might want to try looking at a few of the examples in our example finder. You can access these by choosing Help - Find Examples. For file I/O, you should look under Fundamentals - File Input and Output. As far as acquiring voltage readings, could you provide a little more information about the hardware you are using? Are you using our DAQmx driver? If so, you should check out the examples under Hardware Input and Output - DAQmx - Analog Measurements - Voltage. Also, what exactly about your code is not working? Are you receiving an error code, or is the data incorrect?

Good luck with your application!
