6.4.3 Display Rounding (INIt > RdG > d.RNd)
Select the Display Rounding (d.Rnd) option.
The Display Rounding parameter determines the minimum change in value required to cause
the display to update.
For example, if the d.RNd value is set to 5.0, the displayed values will be 0, 5, 10....
The D.RND value only affects the value being displayed. It does not affect the absolute value
being read or the value(s) used for control functions.
Select the indicated option.
6.4.4 Filter (INIt > RdG > FLtR)
Select the Filter (FLtR) parameter. Filtering averages multiple input analog to digital
conversions, which can suppress noise in the input signal. This should be set to an appropriate
value depending on the response time of the input.
Navigate to the desired setting corresponding to the number of readings per displayed value.
Settings include the following (calculated times between display value updates are shown for
each setting as well):

8 – 0.4 s (factory default)

