at a slower cycle time. Recommendation: exit the envelope curve display after
optimizing the measuring point. Press (the device does not leave the envelope
curve display automatically.)
Conditions

• There should be practically no interference echoes in front of the actual level signal
• Interference echoes must be below the mapping curve
