184.108.40.206. Adjustment of a magnetic deviation
The corner of a magnetic deviation is various in various places of the planet, but its approximate card is shown in the drawing.
In some areas the indication of a compass on the North (the magnetic North) will differ from the direction on the North on the card.
It occurs owing to an inclination of an axis of rotation of Earth. This deviation is called a magnetic deviation, and the deviation on 20 ° on the West and on 20 ° on the East can be adjusted with a step in 5 °.
If the magnetic deviation of the direction on the North shown by a compass (on the magnetic North), from the direction on the North on the card makes 5 ° to the West.
1. Press the button adjustments of a compass (1) and the button of adjustment of a magnetic deviation (2) at the same time on 1–2 with, there will be an index of the North (W–N–E), the scale and a point specifying the direction (3). Now graduation of a scale changed with 22,5 to 5 ° on division.
2. Every time when pressing the button of adjustment of a magnetic deviation, the index moves clockwise on one division of a scale. If long to hold the button of adjustment of a magnetic deviation, the point index will begin to move automatically. Release the button, and the point will stop.
3. Press the button adjustments of a compass on 1–2 with, and the point index will begin to blink. When the point ceases to blink and it will be necessary to burn, adjustment will be complete.
