VEGA VEGASON 71 - 2 … 75 - 2 - Manual (Page 44)

Working range reduction
44 71 - 2 … 75 - 2
Working range MODE 1 - 05 … 1 - 08
The working range can be limited in this mode by
programming of
-
start of working range and
- end of working range in case of failure.
Echoes outside this limitation are ignored, e.g.
-
false echoes in the narrow range
- multiple echoes by reflection in empty vessels
(see programming example)
Note:
In case of multiple reflections, a limited operating
range may not be sufficient. The end of working
range should be programmed min. 10 % > than the
max. vessel height.
min. distance (e.g. VEGASON 74 - 2)
max. vessel distance
end of working range
max. distance (e.g. VEGASON 74 - 2)
Programming example:
Indication of distance in m ........................................ • can be indicated in mode 1 - 05
Indication of gain in dB ............................................. • can be indicated in mode 1 - 06
Start of working range ............................................... • mode 1 - 07 is here indicated as programming
example
End of working range ................................................ • select mode 1 - 08 in MODEFIELD
• program 14.00 m in PARAMETER FIELD
• then store with STO-button
0 m
