Parameter
Description
Range
Accumulation
Number of accumulations.
Higher values enhance the range and reduce the
measurement rate and noise.
When you increase the accumulation value, you reduce the
noise as well as the measurement rate. Depending on your
application, a reduction of the noise might be more
important than a high measurement rate.

Oversampling
Number of oversampling cycles.
Higher values enhance the accuracy/precision/resolution
and reduce the measurement rate.
When you increase the accumulation value, you increase
the resolution (accuracy) but you reduce the measurement
rate. Depending on your application, a higher resolution
might be more important than a high measurement rate.

Points
Number of base sample points.
Determines the maximum detection range. The more
points there are, the more they have an impact on the
processing load since it impacts the number of sample
points to process for each segment.
