Vernier caliper reading method

Vernier calipers are used with the reading method.

Vernier caliper reading method and how to use it.

Vernier caliper, as a commonly used measurement tool, is generally accurate in the name of its accuracy, but its structure is relatively much more complex than that of a tape measure. So here's how to use it.

Material tools.

Vernier calipers. Method.

Regardless of the measurement method, the data is now on the scale, so the diagram below shows the measurement of the inner diameter.

First, look at the position of the sub-ruler "0", which determines the first two digits. 0 in the figure is behind . That is, the inner diameter of the measured object is.

Then observe the sub-ruler indexing (accuracy), that is, how many grids are 20 divisions, that is, the accuracy is. (Units per index = 1 mm division).

Look at the digits that the secondary ruler and the main ruler completely coincide, and look at the red box, the overlapping part is 3 squares different from the two. That is, the overlap is 17. Each unit is , the final digit is obtained, and the final measurement is that the inner diameter of the target is.

Summary. 1.Read out a fixed scale value: There is a longer ruler on the vernier caliper, which is measured in millimeters or inches, and its reading is first looked at when the measurement, which is the maximum reading.

1.Read out a fixed scale value: There is a longer ruler on the vernier caliper, which is measured in millimeters or inches, and its reading is first looked at when the measurement, which is the maximum reading.

2.Read out the vernier scale: There is a vernier on the ruler of the vernier caliper, and the vernier is parallel to the ruler surface and perpendicular to the fixed scale value.

When measuring, place the vernier caliper on the measured object, and the lower end of the vernier leans against the edge of the measured object, and see the position where the scale mark on the vernier and the scale mark on the ruler surface coincide. The tick mark on the cursor is the decimal number, through which the width or diameter of the object to be measured can be read. The basic principle is to read as accurately as possible the position of the nearest ruler tick mark to the left of the cursor mark.

3.Reading out the engraved lines on the counting wheel: Multiplication dimensions are required to increase the accuracy of readings when measuring workpieces with vernier calipers and high reading requirements.

There is a counting wheel in the vernier caliper, and there are three or five notches on the counting wheel, each of which represents a unit. When the tick mark reading on the cursor reaches a certain value, the tick marks of multiple counting wheels appear.

In this case, the following points should be noted: correct positioning of the engraving of the counting wheel; Note whether the counting wheel has five or three engraved lines; Push the vernier caliper forward or backward to turn the counting wheel one scale.

Pro, the reading method of vernier calipers is as follows:1Place the vernier caliper on the object to be measured and clamp the two measuring nozzles against the object.

2.Determine the zero point of the vernier caliper, which is the distance between the two measuring nozzles of the vernier caliper. 3.

Read the integer number of digits on the cursor caliper, which is the number closest to the zero point on the cursor. 4.Read the number of decimal places on the vernier caliper, which is the number on the cursor adjacent to the zero point of the base width, multiplied by the graduation value of the vernier caliper.

5.Add the number of integers and decimal places to get the measured value. For example, if the integer number of vernier calipers is 5, the number of decimal places is millimeters, and the graduation value is millimeters, the measured value is millimeters.

Hello, dear <>

According to the question you provided, the following is available for you: The method of reading the vernier caliper is as follows: first place the two hooks of the vernier caliper on both ends of the object to be measured so that they fit closely with the object.

Read the integer scale on the main ruler, i.e. the number on the main ruler that is close to the object being measured. In general, this number is measured in millimeters or centimeters. Read the tick marks on the cursor.

The long tick marks on the cursor indicate millimeters, and the short tick marks indicate millimeters. If the tick marks of the cursor coincide exactly with the tick marks on the master ruler, the cursor reads as the number on the integer tick plus the value represented by the tick excitation line of the vernier scale. If the tick marks on the cursor do not coincide exactly, the reading of the cursor needs to be determined by observing where the tick marks of the vernier coincide with the scale marks of the main ruler.

The last exact coincident tick mark on the cursor represents the millimeter difference between an integer scale on the master ruler and the cursor. Therefore, the reading of the vernier is the number of tomorrow morning digs on the integer tick plus the number of millimeters where the vernier tick mark is located.

Vernier calipers are a commonly used measuring tool, and here are the reading methods for vernier calipers:1Double-check the scale of the vernier caliper:

There are two scales on the vernier caliper, one is the main ruler and the other is the cursor. The minimum scale of the main scale is usually millimeters or millimeters. The minimum graduation value of the cursor is millimeters.

2.Determine the measurement object: Place the vernier caliper on the object to be measured and clamp it to keep it in a fixed position.

3.Read the main scale: The main scale on the vernier caliper represents the length of the integer part, for example, if the number 10 on the main scale is 10, it means that the length of the measurement object is 10 mm.

4.Read the cursor scale: The cursor scale on the vernier caliper represents the length of the decimal part.

When reading the cursor scale, you need to align the cursor to the side of the main scale closest to the measurement object. For example, if the cursor stays between 8 and 9 on the main scale, it means that the decimal part is millimeters. 5.

Calculate the total length: Add the readings of the main scale and the vernier scale to get the total length of the measured object. It is important to note that when reading vernier calipers, errors should be minimized as much as possible.

To do this, measurements need to be as precise as possible and stable and accurate at the time of reading.

Summary. Hello, vernier caliper reading method: vernier caliper reading to the scale mark is located between two values, read to take the integer, the value of the vernier ruler should be flush with the scale mark on the size, and then read out the measured value according to the formula, the vernier caliper is based on the above tick mark when reading, generally speaking, if the scale is located between two values, read the integer when reading, that is, the small number of millimeters, read the value that the vernier refers to, There is also the tick mark on the ruler that is flush with the tick mark on the size, and according to the value of the nearest line, the reading formula is that the measurement value is equal to the measurement value of the master ruler reading plus the vernier ruler reading.

Hello, vernier caliper reading method: vernier caliper reading to the scale mark is located between the two values, read to take the integer, the value of the vernier is the ruler and the size of the scale file line flush, and then according to the formula to read the measured value, vernier caliper in the reading, is based on the above tick mark, generally speaking, if the scale is between the two values, read the integer, that is, the small millimeter finch finger, read the value of the vernier refers to, There is also the tick mark on the ruler that is flush with the tick mark on the size, and according to the value of the nearest line, the reading formula is that the measurement value is equal to the measurement value of the master ruler reading plus the vernier ruler reading.

Extended information: Vernier caliper is a measuring tool for measuring length, inner and outer diameter, and depth. The vernier caliper consists of two parts: the main ruler and the vernier attached to the main ruler that can slide.

The main ruler is generally in millimeters, and the vernier has or 50 sub-grids, according to the different sub-grids, vernier calipers can be divided into ten-degree vernier calipers, twenty-degree vernier calipers, fifty-degree vernier calipers, etc., the vernier is 10 indexes scattered with 9mm, 20 indexes with 19mm, 50 indexes with 49mm. There are two sets of movable measuring jaws on the main ruler and the free-belt digging answer mark of the vernier caliper, which are the inner measuring jaw and the outer measuring jaw, the inner measuring claw is usually used to measure the inner diameter, and the outer measuring claw is usually used to measure the length and outer diameter.
