How to use the compass correctly?

To use it correctlyCompassWhen using a compass, you need to stay away from items that generate magnets, such as cars, barbed wire, and moreHigh-voltage linesetc., and it is best to keep the distance at least 10 meters, otherwise it will affect the accuracy of the compass presentation results. In addition, the compass should be kept level when placing it, otherwise it is easy to cause errors in the compass results.

When the compass is placed horizontally, the needle will stop oscillating, so that we can accurately see the north and south positions, if the compass cannot accurately determine the north and south positions, it is generally possible that the magnetic field interferes with the compass.

Modern electronic compass:

The electronic compass can be divided into a planar electronic compass and a three-dimensional electronic compass. Planar electronic compass requires the user to keep the compass level when using it, otherwise when the compass is tilted, it will also give a change in heading, but in fact the heading does not change.

Although the planar electronic compass is very demanding when used, if the carrier attached to the compass can be guaranteed to be always level, the planar compass is a cost-effective choice.

The three-dimensional electronic compass overcomes the strict limitations of the planar electronic compass in use, because the three-dimensional electronic compass adds an inclination sensor inside it, and if the compass is tilted, the compass can be tilted to compensate, so that even if the compass is tilted, the heading data is still accurate.

Sometimes, to overcome temperature drift, the compass can also be built in temperature compensation to minimize tilt angles.

and temperature drift of the pointing angle.

The process of using the compass on the Apple 5 is as follows: Calibrate the compass: The compass needs to be calibrated when it is first used, and it may need to be recalibrated from time to time after that.

Find Direction: Find the direction the I Phone is pointing: Hold the I Phone horizontally (parallel to the ground).

Its orientation is shown at the top of the screen, while its position is shown at the bottom. Toggle between true north and magnetic north: Tap .

Use a compass with a map: The Compass app can also display your current location and orientation on Maps. See your current location in Maps:

Tap Compass at the bottom of the screen. Maps opens with a blue marker showing your current location. Orientation shown:

In Maps, double-tap . The icon changes to: The angle shows the accuracy of the compass readings:

The smaller the angle, the higher the accuracy.

Place the compass flat and free of magnetic fields. After the pointer swings to stop, look at the pointer, needless to say, there are Chinese characters south and north. If it is marked with n and s, then n is north and s is south, and it can be used if you can distinguish north and south, and you must keep the compass level during use.

Take out the compass and make the magnetic needle in the compass overlap the straight line at the bottom. Generally speaking, a good compass has two colors, and the color of the magnetic needle is the same as the color of the bottom line, which is the north. For example, the color of the magnetic needle is half red and half black, and the bottom line is red, and the magnetic needle is stacked on the straight line, because the bottom is red, and the red part of the magnetic needle refers to the north (n).

The correct way to have a compass:

1. When using the compass, it is necessary to stay away from items that will produce magnets, such as cars, barbed wire and high-voltage wires, etc., and the distance should be kept at least ten meters, otherwise the accuracy of the compass results will be affected. In addition, everyone should keep the compass level when placing it, otherwise it is easy to cause errors in the compass results, which everyone needs to pay special attention to.

2. In fact, the use of the compass is very simple, after placing the compass horizontally, the pointer will stop swinging, so that you can accurately see the north and south positions, if your compass can not accurately see the north and south positions, it is generally the magnetic field that interferes with the compass.

3. Friends who want to find the direction through the compass, you can turn the compass slowly, when the pointer coincides with the "north" of the compass dial, you can know the direction you are in, and even the direction of the face can be clearly understood. Some professional compasses have many functions, so it is recommended that you read the manual carefully before using them.

Learn how to read the compass:

1. From the point of view of appearance, the dial of the compass is very similar to the watch, showing a circle, and with a circle of very accurate scales, the south is a place with a scale of 180 degrees, the north is a place with a scale of 0 degrees, the east is a place with a scale of 90 degrees, and the west is a place with a scale of 270 degrees.

2. When the compass is stationary, the direction of the red end is south, and then you slowly turn the compass until the white end coincides with the "south" displayed on the dial scale before it can stop rotating, and the direction pointed by the compass is your actual geographical direction. Before looking at the compass, you should first pay attention to whether there are any objects that generate magnets around you, and if there are, you should try to stay away from them.

Summary. Dear, glad to answer for you! The correct way to use the compass is as follows:

When using the compass, you need to stay away from items that generate magnets, such as cars, barbed wire, and high-voltage wires, and keep the distance at least 10 meters, otherwise it will affect the accuracy of the compass results. In fact, the use of the compass is very simple, after placing the compass horizontally, the pointer will stop swinging, so that you can accurately see the north and south positions, if your compass can not accurately see the north and south positions, it is generally the magnetic field interference.

How to use the compass correctly.

Dear, glad to answer for you! The correct way to use the compass is as follows: when using the compass, you need to stay away from items that generate magnets, such as cars, barbed wire, and high-voltage lines, and keep the distance above 10 meters, otherwise it will affect the accuracy of the compass results.

In fact, the use of the compass is very simple, after placing the compass horizontally, the pointer will stop swinging, so that you can accurately see the north and south positions, if your compass can not accurately see the north and south positions, it is generally the magnetic field interference. If you want to find your way through the compass, you can turn the compass slowly, and when the pointer coincides with the "north" of the compass dial, you can know where you are.

The compass, called Sinan in ancient times, is mainly composed of a magnetic needle mounted on the shaft, the magnetic needle can rotate freely under the action of the natural geomagnetic field and remain in the tangent direction of the magnetic meridian, the south pole of the magnetic needle points to the geographical south pole (magnetic field North Pole), and the direction can be identified by using this xing energy. It is commonly used in navigation, geodesy, travel and military applications. There are three types of components for the compass that physically indicates the direction, namely the Sinan, the compass and the magnetic needle, all of which belong to Chinese inventions.

Let's first understand the structure of the compass: the compass is composed of a circular disc with a 360-degree scale, a pointer, and characters representing the four main directions of southeast, south, and north.

If you look closely, the pointer is around the circumference, and it will move along the tick mark as the bearing changes. Red is shown on the 0-degree tick and black on the other ticks.

A scale of 0 is due north, which is indicated by the red letter "north", and the hands also turn red.

Take 0 degrees as the starting point and follow the clockwise direction to 90 degrees, which is due east.

Continue in a clockwise direction to 180 degrees is due south.

Continue clockwise to 270 degrees is due west.

After the four main directions of due north, east, south and west are fixed, the other directions are represented according to these four main directions. For example, if the pointer points to 21 north, it means that the bearing is 21 due north.

Classification of the compass:

Compasses can be divided into two categories: those that rely on magnetism and those that do not. Compasses that rely on magnetic force can be further subdivided into two categories:

One is a geomagnetic compass made according to the polarity of the earth's magnetic field, but the north-south direction indicated by this compass is different from the true north-south direction, and there is a magnetic declination;

The second is the electronic compass, which uses the magnetoresistive (MR) technology of the magnetic field sensor, which can well correct the problem of magnetic declination, and has been widely used in satellite positioning devices. For those that do not rely on magnetic force, the pure carrying cover relies purely on the physical methods inside the device to indicate the direction, such as a guide car or an inertial navigation system.

The compass is also known as the north arrow because modern needles are often painted with a color mark on the end of the point to the north so that the user can find the north.

How to use the compass, use the compass to make the map and the actual terrain the same bearing, find out where you are and the direction of the destination you are looking for. The compass must be held horizontally and away from the following items to avoid confusion of the tall and thick needle: the compass should be 10 meters away from barbed wire, 55 meters from high-voltage lines, 20 meters from cars and airplanes, and 10 meters from magnets such as magnetic containers.

The compass, called Sinan in ancient times, is mainly composed of a magnetic needle mounted on the shaft, the magnetic needle can rotate freely under the action of the magnetic field of Tianli Nian Luran and remains in the tangent direction of the magnetic meridian, the south pole of the magnetic needle points to the geographical south pole (magnetic field North Pole), and the direction can be discerned by using this performance.

1. In the "Tools" or small applications of the mobile phone, there is a "compass" icon, open it after finding it. However, some models require a separate installation of the APP, but the operation procedure is the same after the installation is completed.

Second, after clicking on, some mobile phones will encounter a box prompt that "Compass" needs to get the location, and we can click on the blue word "Allow".

3. Hold the mobile phone tightly and put it on the position, and a triangular pointer will immediately appear in the disk, and the direction of this triangle is the corresponding direction.

Fourth, I regretted a little bit of searching and moving, and there was a slight change in the direction, such as the pointer pointing to the position of the north by west, and even the degree was displayed very accurately.

Fifth, some "compass" to the right can also turn a page, in the interface will display two plane embedded gray and white circles, will measure the angle of the mobile phone.

Sixth, put the mobile phone upright, we can carry out a guide to the real scene, will give the direction according to the framing information, this is more vivid, whoever looks will know the basic four directions.

01 Take Huawei P40 mobile phone, system as an example, how to use the mobile phone compass: 1. First turn on the positioning function of the mobile phone, then find the compass function that comes with the mobile phone, and click to enter. 2. After entering, you need to simply calibrate the compass, and you can gently shake the phone.

3. After the calibration of the mobile phone compass is completed, you can check the status of the compass, and it will also display information such as latitude and longitude, its own location, etc.

In daily life, everyone uses navigation the most, and rarely uses the compass, and some netizens have not turned on the "compass" function of the mobile phone for a long time. Let's take you to dig out the functions and usages of the "Guide Pin Needle" that comes with the mobile phone.
