MENU 4.3 UPDATE RATE - DEFINES HOW MANY MEASUREMENTS ARE USED TO CALCULATE AN AVERAGE

This section refers to Menu points 4.1 - 4.3.
Setting the filter level to 0 will disable the filters
in either modes (0 or 1). The Gaussian filter type
IIR (mode 0) filter level 4 is the factory default.
This provides a slower response with a high
level of damping. The FIR filter type provides
better response where high speed is required.
Both types of filter can be enhanced further by
using the UR parameter Menu 4.3 to average
between 1 (UR=0) and 128 (UR=7)
measurements.
