P24: - - - a Target tracking speed
With this parameter the evaluation can be sped up at the expense of the accuracy.
a Tracking speed Remark
0
Standard For most applications
1
Fast For fast changing level
2 Special
For very special cases only, as this reduces the maximum measuring range to 50% of the nominal value! The
measuring window (P25 and P33) is inactive and the EasyTREK will respond practically instantly to any target.
FACTORY DEFAULT: 0
P25: - - - a 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)

"t" ultrasound flight time
Echo 2.
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.
