[usage]

Scale on stainless steel compass

South is 180

North is 0.

\"East\" is 90

West is 270

English letter meaning:

East (east)

W (west)

South (S)

north

NE NE, SE SE SE, SW SW, NW

The red arrow points south
Turn the compass, when the pointer to stabilize, the red end always refers to the north, and then gently turn the compass, the letter \"N\" with the red arrow (point), then the other letters on a compass direction of the corresponding is the actual location, so you can distinguish between north and south, east and west, and then can also, determine any or other in one direction and north direction Angle, can read on the dial.

[usage]

Step 1: place the compass horizontally. When the compass is stationary, the red section points south.

Step 2: slowly turn the compass until the red end coincides with the \"south\" of the scale

Step 3: the direction indicated by the dial is the actual geographic direction

Note: magnets and iron articles will affect the accuracy of the compass. Please do not use the compass near magnets (such as speakers) or iron (knives, etc.).

[maintenance and maintenance]

1. Keep away from ferromagnetic objects, high voltage wires and electromagnetic devices when using and placing the compass needle

Pieces, etc., so as not to cause errors and reduce the sensitivity of the compass.

2. When not in use, keep in a ventilated and dry place to avoid mildew.

3. When the surface is dirty, white flannelette can be used to wipe the surface gently to keep the surface smooth and clean.

【 about the compass 】

The compass is a simple instrument for determining bearing. The compass was formerly known as sinan, one of the four great inventions of ancient China. The main component is a freely rotating magnetic needle mounted on a shaft. A magnetic needle can remain tangent to the magnetic meridian under the action of a geomagnetic field. The North Pole of the magnetic needle points to the geographic North Pole. It is often used in navigation, geodesy, travel and military affairs.

The earth is a big magnet, its magnetic North Pole near the geographic North Pole, magnetic North Pole near the geographic South Pole.
The compass in the earth's magnetic field by the force of the magnetic field, so will guide one end of the north point. Compass -- people pay attention to the activity of the sun historically, has this name
North needle - the northern hemisphere is relatively close to the magnetic North Pole, and professional mapping needs to consider the geographic North Pole and magnetic North Pole deviation Angle (magnetic deviation Angle), so now most call the north needle. They're the same thing.

The compass must be held horizontally. To avoid confusion of the magnetic needle, keep a certain distance from barbed wire, high voltage wires, cars and airplanes, and objects containing magnetism.

【 extract of compass knowledge 】

The compass refers to the geographic South Pole which is geomagnetic North Pole.

The compass was formerly known as sinan, one of the four great inventions of ancient China.

The main component is a freely rotating magnetic needle mounted on a shaft.

A magnetic needle can remain tangent to the magnetic meridian under the action of a geomagnetic field.

The North Pole of a magnetic needle points to the geographic South Pole.

It is often used in navigation, geodesy, travel and military affairs.

The invention of compass is the result of our laboring people's understanding of object magnetism in long-term practice. As a result of production labor, people came into contact with magnetite, began to understand the magnetic nature. It was first discovered that magnets lead iron. Later, the directivity of the magnet was discovered. After many experiments and studies,

Finally, a useful compass was invented.

The principle of compass direction

The earth is a big magnet, its magnetic North Pole near the geographic North Pole, magnetic North Pole near the geographic South Pole. The compass is under the force of the earth's magnetic field

So it will guide one end and point north the other.

[operation]

1. Measure azimuth

Bearing box that is rotated a compass, the glass scale and direction of the indicators are relatively, put (45 degrees) the head-up mirror inclined monocular by accuracy aiming target, from a heads up a mirror to see the magnetic North Pole on the word table bearing partition on the card, can be read out the target, azimuth Angle, and then turn the bearing box with his right hand on bearing glass scale line aim with the magnetic North Pole, the direction indicator and azimuth Angle of glass scale line between is the target direction Angle (clockwise).

Open the compass needle, mark the map (the map can not be calibrated when ranging), insert a needle at the datum point on the map, turn the compass needle to make the edge of the measuring ruler cut at the target point, then the azimuth Angle from the datum point to the target point can be interpreted.

2. Map calibration

A compass, rotating bearing frame, make the bearing box and direction indicator on the scale line on the word (note the magnetic declination correction), put behind the flat map, thumb side toward the map in the arctic, the coordinates of ladder feet long and the magnetic meridian tangent maps, the map to the magnetic North Pole alignment is rotated the scale lines on the glass, the map that has been calibration.

Introduction to compass

Compass is system kamyu geomantic advanced professional compass, it is the compass of any one faction geomantic lover above all, the content that geomantic learn to need shows, make fine when, select material is excellent, have certain weight, feel is admirable, it is geomantic lover handy good tool. Easy to carry, elegant style, is the construction, survey and other professionals necessary tools.

The compass, also known as the compass, is an important tool for feng shui masters of the yi jing in Chinese history. Today, feng shui is not only popular in the overseas Chinese world, but also highly valued by foreigners. People also use a compass to trick nagy. Regardless of any school of compass, engraved with a large number of Yin and Yang boundary data, can be said to be a very powerful symbol. The power of compass is innate gasification acquired intangible evil, it has three best characteristics: evil, town house, fortune.
