4 Details of the
selected echo
Clicking on a column from the echo sample displays the following
detailed information in the "Details of the selected echo" area:
• Echo number: The echo number is a consecutive number
which numbers the echoes shown in the graphic from left to
right.
• Frequency of occurrence: The value of the frequency of occur-
rence indicates how often the selected echo occurs in the cur-
rently displayed number of echo samples.
• Amplitude: The strength of the amplitudes of the selected
echo is displayed as a % value
• Distance: The distance indicates the distance corresponding
to the displayed echo value, measured from the sensor sur-
face in mm.
Note: The displayed distance value always refers to the run-
time measured by the sensor after the relevant echo was
taken. This does not mean that an object has to be physically
present in each of these distances. For example, if an object is
located close to the sensor, so-called multiple echoes may
occur. This involves reflecting the sound pulse of a measure-
ment back and forth several times between the sensor and the
object. The sensor sees each fresh echo reflected from the
object as its own echo and provides it accordingly. These mul-
tiple echoes can be identified in the graphic as echoes in the
x-times actual object distance.
• Suppressed: When indicating suppression (yes/no), the dis-
plays shows whether the selected echo exceeds or falls below
the switching threshold. If the echo amplitude exceeds the
switching threshold, the echo is "not suppressed," but can be
evaluated by the sensor. If the echo amplitude is lower than
the switching threshold, the echo is "suppressed."
• Reserve to threshold: The threshold reserve value indicates
how reliably an echo is detected or suppressed. This value is
shaded by traffic light colors so that evaluation can be carried
out easily.
5 Red column The evaluated echo of the last recorded echo samples is dis-
played in the graphic as a red column.
This specific representation makes it possible to subsequently
verify the effectiveness of set suppression areas because the
evaluated echo can be easily distinguished from the rest.
6 Sensor switching
threshold (blue line)
In the graphic, a "blue line" indicates the switching threshold of the
sensor alongside the recorded echoes. Echoes for which ampli-
tude exceeds this threshold can be evaluated by the sensor.
Echoes below the switching threshold are in effect suppressed
and will be discounted.
