[Use]]

stainless steel compass upper scale number meaning:

"South" is 180

"North" is 0 (it can also be said to be 360)

east is 90

west is 270

the letters of the alphabet meaning:

east E

west W(west)

south S

north N

NE northeast, SE southeast, SW southwest, NW Northwest

the red arrow points to the South
turn the compass. When the pointer stabilizes, the red end will always point north, and then gently turn the compass to make the letter "N" coincide with the Red Arrow (pointing the same), then the direction corresponding to other letters on the compass is the actual orientation, so that you can distinguish between east and south, and then you can also determine the angle between any direction and true north or other directions, it can be read on the dial.

[Use]]

step 1: place the compass horizontally. After the compass is still, the red section points to the geographical direction and is "south"

step 2: turn the compass slowly until the red end coincides with the "south" of the scale.

Step 3: at this time, the direction marked by the dial is the actual geographical direction.

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

[Maintenance]]

1. Do not approach ferromagnetic objects, high-voltage wires and electromagnetic devices when using and placing the north pointer.

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

2. When not in use, it should be placed in a ventilated and dry place to avoid mildew.

3. When each surface is sticky, white flannel can be used to gently wipe the surface to keep the surface bright and clean.

[About Compass]]

compass is a simple instrument used to judge orientation. The predecessor of the compass was Sinan, one of the the four ancient Chinese inventions. The main component is a magnetic needle installed on the shaft that can rotate freely. The magnetic needle can be kept in the tangential direction of the magnetic meridian under the action of the geomagnetic field. The north pole of the magnetic needle points to the north pole of geography, which can be used to identify the direction. Commonly used in navigation, Geodetic Survey, travel, military and other aspects.

The Earth is a large magnet whose south magnetic pole is near the geographic North Pole and North Magnetic Pole is near South geographical pole.
The compass is affected by the magnetic field force in the Earth's magnetic field, so one end of the guide will point to the north. Compass-in history, people pay attention to the activities of the Sun, which is called
north pointing needle-the northern hemisphere is relatively close to the magnetic North Pole, and professional mapping needs to consider the declination (magnetic declination) between the geographic North Pole and the magnetic North Pole, so now most people call North pointing needle. The two are one thing.

The compass must be held horizontally. In order to avoid confusion of the magnetic needle, keep a certain distance from barbed wire, high-voltage lines, cars and planes, and objects containing magnetism.

[Compass knowledge excerpt]]

compass refers to South geographical pole, that is, North Magnetic Pole compass is a simple instrument used to identify orientation.

The predecessor of the compass was Sinan, one of the the four ancient Chinese inventions.

The main component is a magnetic needle installed on the shaft that can rotate freely.

The magnetic needle can be kept in the tangential direction of the magnetic meridian under the action of the geomagnetic field.

The north pole of the magnetic needle points to the south pole of geography, which can be used to identify the direction.

Commonly used in navigation, Geodetic Survey, travel, military and other aspects.

The invention of Compass is the result of our working people's understanding of the magnetism of objects in long-term practice. Due to the production and labor, people came into contact with magnetite and began to understand the magnetic properties. People first discovered the properties of magnet iron. Later, the directivity of the magnet was discovered. After many experiments and researches,

finally, a practical compass was invented.

Principle of compass indicating direction

the Earth is a large magnet whose south magnetic pole is near the geographic North Pole and North Magnetic Pole is near South geographical pole. The compass is forced by the magnetic field in the Earth's magnetic field.

Therefore, one end of the guide will point to the north.

[Operation]]

1. The measured azimuth

expand the compass, rotate the azimuth frame to make the scale on the azimuth glass and the direction index relatively positive, and tilt the flat mirror (45 degrees) to the target with a single eye through the quasi-star, from the flat mirror, we can see the azimuth division of the inverted word card on the north pole of the magnetic needle, which can not only read the target and azimuth angle, but also turn the azimuth frame with the right hand to align the scale line on the azimuth glass with the north pole of the magnetic needle, at this time, the angle between the direction index and the azimuth glass scale line is the target direction angle (calculated clockwise).

Open the pointer, mark the map (the map cannot be calibrated when measuring distance), insert a needle at the base point on the map, and rotate the pointer to cut the edge of the measuring ruler to the target point, so as to determine the azimuth angle from the base point to the target point.

2. The calibration map

expand the compass, rotate the azimuth box, align the tick line on the azimuth box with the direction indicator (pay attention to the correction of the magnetic declination), place the North pointer flat on the map, and one end of the target star faces the north pole of the map, make the length of the coordinate ladder tangent to the magnetic meridian of the map, and rotate the map to align the north pole of the magnetic needle with the scale line on the azimuth glass. At this time, the map has been calibrated.

[Compass introduction]]

compass is an advanced professional compass for geomancy and geomancy. It is the first compass for any feng shui enthusiast. It displays all the contents required by geomancy, is well-made, has excellent material selection, has a certain weight, and has excellent hand feeling, it is a good tool for feng shui lovers. Easy to carry, elegant and stylish, it is an essential tool for professionals such as architecture and inspection.

"Compass", also known as "Luo Jing", is an important tool for the feng shui master of the Book of Changes in the past dynasties in China. Today, feng shui is not only popular in overseas Chinese world, but also highly valued by foreign people. People often resolve evil spirit Naji with a compass. No matter the compass of any school, there are a lot of data of yin and yang, which can be said to be a very powerful symbol. The power of Compass is the congenital gasification and acquired invisible evil, which has three best characteristics: divide evil, save houses and bring money.
