It is important to have sensors collect data at rate that allows you to measure what you want to measure.
The appropriate sampling speed is one that is fast enough to capture all rapid changes in the measured quantity, but that does not generate an excessive number of points. For example, a temperature probe can take several seconds to reach a new temperature. Anything faster than 1 or 2 samples per second would generate many nearly identical data points.
You can use the collection parameters established in an experiment file or you can change the sampling rate using the following procedure:
