1)
Time span after a sudden measuring distance change by max. 0.5 m in
liquid applications, max 2 m with bulk solids applications, until the output
signal has taken for the first time 90 % of the final value (IEC 61298-2).
2)
Outside the specified beam angle, the energy of the radar signal has a level
which is reduced by 50 % (-3 dB)
