(measuring range is reduced to 50% of the nominal value)
The measuring window (P25) is inactive and the EasyTREK will respond practically instantly to any
target. Recommended to fast target tracking, but usually not applicable for level metering.

Selection of Echo within the measuring window
A so-called measuring window is formed around the echo signal. The position of this measuring window determines the flight time for calculation
of the distance of the target. (the picture below can be seen on the test oscilloscope)

Some applications involve multiple ( disturbing) echoes even within the measuring window. Basic echo selection will be done by the
Quest + software automatically. This parameter only influences the echo selection within the measuring window.
