Function Function description
overfill If this function is switched on,
detection the instrument will monitor
the level even if it is in the
blocking distance. The
displayed output stays fixed at
the blocking distance, but an
error message will warn the
user that the tank is
overfilling.
blocking The distance from the flange
distance to the top limit of the
measuring range. If the
distance is less than the
blocking distance, the
instrument continues to
display the blocking distance.
reference Offset relating to a reference
offset location (distance). This value
is positive when the reference
location is above the device
flange face and negative if
below.
tank bottom Offset relating to a reference
offset 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.
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.
measuring The instrument uses the
mode dielectric constant of the tank
contents to monitor level. If
Er is low and the bottom of
the tank is flat, select "TBF
partial" mode. If you install
the instrument in a process
tank, select "TBF full". For
other uses, select "direct
measuring"
product Er The instrument automatically
calculates the level based on
the product ε
"TBF partial" or "TBF full" in
item C.1.13, you can change
this value manually to adjust
readings.
