Function description
The non-measuring range at the top of the
probe. It depends on the probe type and
the installation.
Refer to the "Default values for menu item
2.3.2 Blocking Distance" table at the end of 2.3.2 Blocking Distance
2.3.2 Blocking Distance 2.3.2 Blocking Distance
this section.
This function gives the time over which the
device will use readings to calculate the
average measurement value.
The device will show a smooth change in
the readings if you increase the time
constant. It is possible that the device will
show sudden, irregular changes in the
readings if you decrease the time constant.
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
How to decrease the
more data, refer to
length of probes
on page 113.
The device has a code (tag name) to
identify it. If the tag name is given in the
customer order data, it will be set at the
factory. A maximum of 8 characters can be
used.
This parameter makes the device ignore
reflections in a specified area immediately
below the process connection. We
recommend that this value is 50 mm / 2¨
less than the value in menu item 2.3.2

Offset in relation to a reference location
(distance). The device reference point for
this parameter is the flange face of the
flange (or thread stop, if the device has a
thread connection). This value is positive
when the reference location is above the
device flange face and negative if below.

Offset in relation to a reference location
(level). The device reference point for this
parameter is the bottom of the tank (set in
menu item 2.3.1 Tank Height 2.3.1 Tank Height). This value is 2.3.1 Tank Height 2.3.1 Tank Height
positive when the reference location is
below the tank bottom and negative if
above. For more data, refer to
