How to trigger data recording to a text file for multiple channels for a certain voltage threshold?

If you want a time column and 3 data columns, you will also have to modify the way your program operates. As it is now, you look at each value from each channel and log each one on a separate line. Do you want to record if all three exceed the threshold, one out of three, etc.?

I want it to record if at least one out of three exceed the threshold, and to write to the text file with a time column.

Try this simple mod.

Right now, it is only recording the values from the first channel, instead of the third channel, which is the one that is actually exceeding the threshold.

Probably something wrong with the conversion of that evil dynamic data. Instead of a single waveform, might need to select 1D Waveform array. Try that.
