Hi IYED,

What errors are you getting when you run your code? Is it Error -50103?  As long as your acceleration and your voltage task are using the same timing parameters, you can combine both channels into a single task.  This should resolve the error you're receiving.  The article below has an image that shows the setup that I'm describing:
