8.3.3 Digital output
8.3.3.1 HART Polling address
Parameter: P19 Default value: 0
Path: OUTPUT SETUP / SERIAL OUTPUT / ADDRESS
Description: HART Polling Address
The polling address can be set between 0 and 15. For a
single instrument the polling address is 0 and the output
is 4-20 mA (analogue output). If multiple units are used
in HART Multidrop mode (max. 15 pcs.) the polling
addresses should differ from 0 (1-15), in this case the
output current will be fixed at 4 mA.
8.3.4 Measurement optimization
8.3.4.1 Blocking, Dead zone
Parameter: P05 Default value: 300 mm
Path: OPTIMIZATION / DEAD ZONE
Description: The instrument ignores all reflections within the dead
zone and the close-end blocking distance. The
disturbing objects and false reflections which are close
to the sensor can be eliminated by entering the dead
zone value manually.
8.3.4.2 Echo selection
Parameter: P25:a, where a: 0, 1, 2, 3 Default value: AUTO
Path: OPTIMIZATION / ECHO SELECTION
Description: Selection of Echo within the measuring window. In order
to avoid disturbing reflections the instrument forms a so-
called measuring window around the reflected signal.
The distance measurement is performed with the echo
signal within the measurement window.

8.3.4.3 Emptying speed
Parameter: P27 Default value: 50 m/h
Path: OPTIMIZATION / EMPTYING SPEED
Description: This parameter provides additional protection against
echo loss in applications involving very heavy fuming
during emptying process. Correct setting increases the
reliability of the measurement during the emptying. The
parameter must not be smaller than the fastest possible
emptying rate of the actual process.
