6.6.3 Mapping
• Factory mapping
Mapping (empty curve) is already available in the device when the device is delivered.
• Customer mapping
In a partially filled state, the distance up to 10 cm before the actual total level can be mapped
(range of mapping = actual distance from total level - 10 cm), or values > LN can be mapped in
the case of empty tanks.
• Dynamic mapping
It is not static like factory and customer-specific interference echo suppression. Instead, it follows
directly from static mapping and constantly adapts to the changing features of the probe
environment during ongoing operation. Thus, dynamic mapping does not have to be recorded
explicitly.
6.6.4 Echo threshold
Maximum points in the difference curve are only accepted as reflection signals if they are above a
specified threshold.
This threshold depends on the location and is automatically calculated from the ideal echo curve of
the probe used.
The calculation of the threshold in question depends on the "Installation" customer parameter in the
extended calibration function.
6.6.5 Navigation in the envelope curve display
With the aid of the navigation, the envelope curve can be scaled horizontally and vertically, or
moved to the right or to the left. The navigation mode that is currently active is indicated by an icon
in the top left-hand corner of the display.
Horizontal Zoom mode

• increases the horizontal scale.
S
• reduces the horizontal scale.
