probe
length
Probe length is the distance
from the flange face / thread
stop of the device down to the
bottom end of the probe
(including counterweight for
cable versions). If probe length
has been modified, enter the
new value here. For more data,
refer to
How to decrease the
length of probes
on page 100.

C.1.10
reference
offset
Offset relating to a reference
location (distance). This value is
positive when the reference
location is above the device
flange face and negative if
below. For more data, refer to
Distance measurement
on page
88.

C.1.11
tank bottom
offset
Offset relating to a reference
location (level). The device
reference point for this
parameter is the bottom of the
tank (set in menu item C.1.2.0).
This value is positive when the
reference location is below the
tank bottom and negative if
above. For more data, refer to
Level measurement
on page
89.

C.1.12
time
constant
Using this function, the device
processes several
measurement readings to filter
out disturbances. Increasing
the time constant will
smoothen the integrated
readings, decreasing will
roughen the readings.
