Calibration of the sensor Case N°2 (Classic example of a manhole with an invert channel)
In case no. 2, with an echo having several peaks, the software indicates the presence of "critical" obstacles that can
disturb the measurement if no modification is done to the calibration. These critical obstacles appear in red on the
graph, while the echo reported by the sensor as the measurement is shown in green. The power indicator (yellow line) is
always present.
In this case, follow the following procedure:
- Activate the advance mode by clicking on the button at the top,
The software displays a first step of calibration that is more precise and named “Measures parameters”: This parameter
allows to extend the exclusion area corresponding roughly to the dead band of the sensor. This parameter is to be
modified, mainly in the case of probes 0-6m if there are interfering echoes in this zone, or in the case of a probe
mounted on an angular return bracket. The manipulation consists in increasing the value of the pink zone so it covers
the different peaks for distances close to the probe,
