Operation Measuring
The following example shows the dependency of dis-
tance measurement on the echo waveform, i.e. on the
height of the gate threshold and thus on the selection of
the intersection point at the signal.
H Note:
The point of amplitude measurement is marked with a
small upward triangle on the corresponding gate bar.
The point of distance measurement is marked with a
small downward triangle.
Gate threshold at 20 %
measured sound path: 24.44 mm
Gate threshold at 80 %
measured sound path: 24.91 mm
