Very slow data recording

We need to record one data point every 5 minutes - how can we do this?

Down sampling from 1 Hz using a sync math channel did not work.

We don't need the RMS, max, min, avg but real data data every five minutes. 

1. Use basic statistics block for time. Change the block size to the number of the seconds between the samples.

2. put the channel in formula, set it on async and pick the basic statistics channel for time.

There is also setup file as an example in the attachment.
