Hi everyone..

I'm a student and I started using labview. Please, could someone help me with a problem?

I'm running tests waveforms charge and discharge of a capacitor, and I want to stay on, collecting data for one week, no interruption.

The block diagram doesn´t measures two inputs at the same time. What am I doing wrong in the block diagram?

You don't have an error out indicator do you don't see the resource reserved error. You must use s single task with multiple channels. Use Dev1\ai0:1 to acquire from both channels. This is a very common mistake.

Thank very much, Dennis.

But, I have one more question, please.

I'm measuring two capacitors, I would like to put each signal in a chart....is this possible?

And sorry because my english is not very good.

It's simple. You're getting a 1D waveform array. Index the array.
