(→ 137):
• The unit defined in the
Distance unit
parameter is used for the basic calibration (

Blocking distance
Navigation
Setup → Advanced setup → Level → Blocking dist.
Description
Specify upper blocking distance UB.
User entry
0 to 200 m
Factory setting
• For rod and rope probes up to 8 m (26 ft): 200 mm (8 in)
• For rod and rope probes above 8 m (26 ft): 0.025 * Sondenlänge
Additional information
Signals in the upper blocking distance are only evaluated if they have been outside the
blocking distance when the device was switched on and move into the blocking distance
due to a level change during operation. Signals which are already in the blocking distance
when the device is switched on, are ignored.
This behavior is only valid if the following two conditions are met:
• Expert → Sensor → Echo tracking → Evaluation mode =
Short time history
or
Long
time history
)
• Expert → Sensor → Gas phase comp. → GPC mode=
On
,
Without correction
or
External correction
If one of these conditions is not met, signals in the blocking distance will always be
ignored.
If required, a different behavior for signals in the blocking distance can be defined by
the Hauser service.
