Toggle mode between
true and relative wind display
In case of both message strings for „True wind“ and rela-
tive wind are available the indicator easily can be toggled
between both modes changing two parameters in the setup
menu „SYSTEM SETUP 2“ which is located in level No. 3 of
the menu structure.
“True wind” mode: protocol „MWD“ & view mode „TRUE“
“Relative wind” mode: protocol „MWV“ & view mode „REL“

Air pressure trend display
The air pressure trend is indicated by arrow symbols (below
the „PRESSURE“ label) as follows:

7.4.3 Mean values
All calculations of the gliding mean values and extreme values
are carried out in the indicator based on the received instan-
taneous data. The following parameters can be selected in
the menu:
• 10 minutes
• 2 minutes
• none (– – – / off)
The finally selected value of the integration time will be indi
-
cated in a field of the normal display mode.
7.4.4 Pre-samples
In some cases the wind indication may be discontinuous due
to turbulent conditions. To obtain a certain damping behavior
of the display a pre-sampling filter can be activated. This figure
in expressed in seconds defines the amount of measuring
values to be integrated to a gliding mean value.
For the update of the display contents the same pre-sampling
interval as selected above is in process.
Example: when an interval of 3 seconds is selected changes
will be indicated every 3 seconds as well.
7.4.5 View mode „REL“ or „TRUE“
This mode allows a selection how to display the wind direc-
tion indicator (wind rose) for the NAV and for the IND version
of the indicator:
• TRUE: N - NO - O - SO - S - SW - W - NW - N
• REL: 0°- 45°- STB - 135°- 180°- 135°- PTB - 45°- 0°
The finally selected mode of display will be indicated in a field
of the operational mode.

Interpretation of the readings
8.1
Specific performance of the wind display
modes with gliding mean values
When the calculation of mean values is selected in the opera-
tion menus before instantaneous and momentary values are
indicated together in one display. The illustration mentioned
here shall describe the relationship between the different
display contents and their meanings.
In case of the calculation of gliding mean WIND values is
switched off (setting: – – –) both parameters will be displayed
as follows:
Wind speed:
Bargraph for tendencies and bold digital characters (7-seg-
ment display)
Wind direction:
Analogue wind rose with a ball-pointer and bold digital char-
acters (7-segment display)
The performance of the display design of the other param-
eters is self-explanatory and does not require any further
information.
