2.3.3. Display of a conclusion of compass readings and sensor of temperature of external air
|
|
The display is located on the ceiling console of the car and allows to define the direction of movement of a vehicle concerning light countries. Besides on the display indications of the sensor of temperature of external air and the prevention of a possible icing of a paving are deduced. |
For a conclusion of indications of the sensor of temperature it is necessary to press the button display control panels at the ignition key turned in the situation ON or ASS. As the main measuring scale the Fahrenheit scale serves, - for transition to a scale of Celsius it is necessary to press the switch button once again. At decrease in temperature below a freezing point on the screen of the display the inscription of ICE warning the driver about danger of a possible icing of a road cloth is deduced.

Limiting borders of a range of measurement are temperatures - 20°F (-30°С) and 158°F (70°С) — at an exit out of limits of the specified range on the display screen instead of digital value will be deduced a line from underlining / dash signs (_ _ _) — it is not necessary to perceive this situation as a sign of refusal of the measuring equipment. At temperature of external air from 130°F (55°С) to 158°F (70°С) on the screen of the display value 130°F (55°С) will be deduced. |
The sensor of temperature of external air is located before a radiator and can perceive heat radiated by the engine and a paving, besides, indications of the sensor are influenced by the direction and speed of a running stream of air, and also a number of other factors. Told means that indications deduced on the display should be considered only as rough (including the prevention of possibility of an icing of a paving), do not forget to listen to regional road news regularly.
The conclusion to the screen of the display of indications of a magnetic compass is made by pressing of the same button control panels — the ignition key should be turned in the situation ON or ASS. The difference between the direction on magnetic and geographical northern poles is called as inducement. Thus the size of inducement depends on a longitude from which measurement is made.
The card of zones of magnetic inducement (For North America)
In case of need definitions of the exact direction to the geographical North Pole follow the following instructions.
|
|
- By the special card determine a zone of your location (see an illustration the Card of zones of magnetic inducement (For North America)), write down result.
|
- Holding the ON/OFF button on the control panel of the display pressed during about 5 seconds, wait a conclusion to the screen of value of number of a zone — in case of need in pressing the same button make the corresponding adjustment.
|
|
- Having achieved demanded result, release the button — within several seconds on the screen of the display the modified compass reading will be deduced.
|
|
|
|
Arrangement near a compass of the magnetized subjects, and also movement within zones of magnetic anomalies can make considerable impact on accuracy of compass indications! |
|
|
At movement in a zone of magnetic anomaly correction of compass readings is made automatically — it is usually enough to make during movement of one-two turn. |
If the automatic proof-reader of a compass does not cope with an objective, necessary fine tuning can be made manually.
|
|
- Deduce the car on the extensive open area.
- Hold the button of management of the display pressed during about 10 seconds — the direction sign should start to blink.
- Slowly moving make some turns.
