The level unit may differ from the distance unit defined in the Distance unit parameter
(→  128):
• The unit defined in the Distance unit parameter is used for the basic calibration (Empty
calibration (→  129) and Full calibration (→  130)).
• The unit defined in the Level unit parameter is used to display the (unlinearized) level.
 Setup → Advanced setup → Level → Blocking dist.

0 to 200 m
For rod and rope probes up to 8 m (26 ft): 200 mm (8 in)
No echos are evaluated within the blocking distance UB. Therefore, UB can be used to
suppress interference echos within the upper end of the probe.
