Read single value within while loop

[StanleyPolytechnique]

Hi,

I have a setup with one output, driving a coil.

I then have two inputs: one to measure the voltage of my coil (the actual voltage) and the second to measure the voltage of a sensor mounted close to the coil.

The setup works fine to monitor both channels continuously, however, I want to monitor the second value only once every 5 seconds.

How can I go about doing this? Every 5 seconds I just want a single measurement from the second channel.

You could just ignore the data from the second channel until your 5 seconds are up.  The Elapsed Time VI should help there.

You haven't given us any info on your device, but I assume it's not super-fancy and can change sample rates per channel.

This article here explains what you want to do. Your device has a single clock, so you're essentially limited to (forces to match?) your highest sampling rate requirement with all channels and then down-sample from there if you don't want all of the data for some of the other channels.
