1. Tap the Meas. Time button.
2. Enter the required value and select a unit.
Configuring the measurement performance
(Config)
Here you can define how measurements are performed.
You selected the desired view.
1. Tap the Config button.
2. Then you can do the following:
Setting the magnetic declination (Magn. Decl.)
Declination is the angle between the direction to the Arctic magnetic pole of the Earth and
the geographic north direction. Since the declination depends on the location and changes
over time, it must be adjusted accordingly. The value can be taken from a map of the region
you are moving in.
The magnetic declination has to be set only, if Compass is used to determine the north
reference (see
Configuring the north
Setting the magnetic declination:
1. Tap the Magn. Decl. button.
2. Turn the Rotary knob or enter a value to set declination.
3. Press the Rotary knob or tap the OK button.
Configuring the north reference (North Reference)
Bearings are displayed in the polar chart of the Bearing view. The angles plotted at the polar
chart are the direction relative to a given north reference. This north reference can be
determined in three ways:
Compass
The ADFA has a built-in magnetic compass. When Compass is selected, the bearings in the
polar chart are showing the direction related to magnetic north (0° means north, 180° south,
...).
In order to transfer the displayed direction to the map, the local magnetic declination must be
determined and entered (see
Some important notes, when using the Compass setting:
• If the ADFA is mounted on a tripod, you can use this method to align all bearings to north.
• When the ADFA is mounted on a vehicle, the Compass method should NOT be used due
to the metallic environment and the magnetic mount adapter.
• Always ensure, that the compass calibration is still valid (e.g. using another compass for
comparison).
