How to use calipers, how to use calipers to measure correctly

There are 4 steps to <> the correct use of caliper measurement, which are to observe the size of the workpiece to be measured, observe the workpiece to be measured, pull the caliper open, and record the caliper reading.

1. Observe the size of the workpiece to be measured: see if it exceeds the measurement range of the caliper.

2. Observe the workpiece to be measured: understand the requirements of the measured workpiece, whether to measure the length of the outer diameter or the length of the inner diameter, or to measure the depth of the aperture.

3. Pull the caliper with both hands to a suitable distance: put it in the place where the workpiece is measured, and push the ruler with the thumb of the right hand to measure the distance between the two points of the workpiece.

4. Record caliper readings: lock the positioning screws with the left hand, remove the calipers from the measuring workpiece, and then read and record.

The correct way to use an electronic caliper is:

1. Before use, wear gloves and wipe the end face of the measuring claw with alcohol to avoid dust, iron filings, etc., which will affect the measurement accuracy.

2. Turn on the power supply, so that the two fingers of Weiqing check the previous claw is completely closed, to see if the number is zero, if not, press the zero button to zero, so three times.

3. When measuring, the caliper should be perpendicular to the measuring surface.

4. When measuring the inner size, the measuring jaw should be opened smaller than the measured size; Then slowly push or pull the vernier caliper.

The sub-ruler measuring jaw gently touches the surface to be measured.

5. Reading method: direct reading. With the metric and imperial transfer switch, you can read both metric and imperial numbers.

How to use calipers.

How do I use calipers? The use of calipers is nothing more than measurement and reading. On the question of how to read, we have already introduced the method of caliper reading. The following is mainly about the measurement method of calipers.

1. Hold the ruler with your right hand when measuring, and then use your thumb to move the vernier of the caliper. Hold the object with the outer (or inner diameter) to be measured in your left hand. The object to be measured is located between the outer measuring jaws, and when it is tightly attached to the measuring jaws, it can be read.

2. There are scales on the ruler body of the caliper and the vernier ruler. Vernier calipers accurate to the millimeter.

For example, the minimum index on the ruler body is 1 mm. There are 10 small divisions on the vernier ruler, with a total length of 9 mm, each of which is millimeter, which is a millimeter difference from the minimum division on the main ruler.

3. When the measuring claws are brought together, the ruler body and the zero scale mark of the vernier are aligned. Their first tick mark is one millimeter apart, the second tick is millimetre, and by the time the 10th tick mark is 1 mm, i.e. the 10th tick mark of the vernier is exactly aligned with the 9 mm tick mark of the master ruler.

4. Similarly, when the fifth tick mark of the vernier is aligned with the 5 mm tick mark of the ruler body, it means that there is a millimeter width between the two measuring claws, and so on. When measuring a length greater than 1 mm, the whole number of millimeters should be read from the tick mark opposite the "0" line of the vernier body.

How to use calipers.

Caliper's**.

Calipers are relatively professional measuring tools, and many users will ask whether calipers are expensive? How much is the average number of calipers on the market now? Let's introduce the ** of calipers. If you are interested, let's take a brief look!

In fact, there are many different types of calipers. There are also differences between different types of calipers**.

1. Vernier caliper.

Vernier calipers are the vernier calipers used by many schools when teaching students. This caliper needs to be read by the user himself. And the accuracy of the vernier caliper.

Comparatively high. The ** of the upstream calipers on the market is not very expensive. The ** of the upstream caliper in the market is generally about 200-400 yuan.

2. Metric and British conversion anti-coolant.

Digital calipers. Metric to inch conversion coolant protection digital calipers can be used in a shop floor environment exposed to coolant as well as water, dust, or oil. The ** of this caliper is much higher than that of the vernier caliper. The general market ** is about 1200 yuan.

3. Calipers with tables.

Calipers with gauge allow for extremely smooth gliding and good shock protection. In addition, the dial-style mobile world is convenient for users to read. The ** with table calipers on the market is about 500 yuan.

4. Metric and British conversion digital calipers.

Metric to British conversion digital calipers use a unique ABSOLUTE encoder.

technology, with the ability to automatically display readings. The ** of the metric British conversion digital caliper on the market is about 800-900 yuan.

5. Digital calipers.

The digital caliper is also made using the unique Absolute encoder technology. The ** of digital calipers on the market is about 800 yuan.

Caldivi (calliper) is a kind of measuring tool, composed of the main ruler and vernier, used to measure the length, inner and outer diameter, depth, with the role of measurement and inspection, when measuring, the right hand holds the ruler body, the thumb moves the vernier, and the left hand holds the object of the outer diameter (or inner diameter) to be measured, so that the object to be measured is located between the outer measuring claws, and when it is closely attached to the measuring claw, it can be read. There are scales on both the ruler and the vernier ruler. Take the vernier caliper accurate to the millimeter as an example, the minimum division on the ruler body is 1 mm, and there are 10 small equal divisions on the vernier ruler, with a total length of 9 mm, and each division is millimeters, which is a millimeter difference from the minimum division on the main ruler.

When the measuring claws are brought together, the ruler body and the zero scale mark of the vernier are aligned, and their first scale mark is separated by millimeters, and the second scale mark is separated by millimeters by ,......The 10th tick mark is 1 mm apart, i.e. the 10th tick mark of the vernier is exactly aligned with the 9 mm tick mark of the master ruler. When the linearity of the object measured between the measuring claws is millimeters, the vernier ruler should be moved to the right by millimeters. At this point, its first tick mark is exactly aligned with the 1 mm tick mark of the ruler.

Similarly, when the fifth tick mark of the vernier is aligned with the 5 mm tick mark of the ruler body, it means that there is a millimeter width ,...... between the two measuring jawsAnd so on. When measuring a length greater than 1 mm, the whole number of millimeters should be read from the tick mark opposite the "0" line of the vernier body.
