11.2 Setting hysteresis (switch-off threshold)
In order to prevent any intermittent cut-out in the coverage signal in the case of vehicles with high
substructures such as articulated buses, trams or HGVs with trailers, it is possible to change the switching
hysteresis (switch-off threshold). Interruption-free detection of critical vehicles is then also possible at a lower
sensitivity.
