13.9 What does data reduction do and how do I set it?
To avoid unnecessarily increasing the amount of data generated, the number
of values to be checked (and possibly saved) is limited: Data reduction. In this
way you can determine how high the display resolution of the relevant channel
should be. As soon as the current measured value for either the x-channel or
the y-channel exceeds the old measured value, a
triple measured value is saved, i.e. the values for both channels plus the time
value. This way, the resolution of your measured values in the x and y-direc
tions will always be at least as good as specified here.
Important
You should record at least 200 to 500 measurement points to enable correct
analysis.
