Cara Menghitung Jangka Sorong dan Mikrometer Sekrup

>Hello Sohib EditorOnline, in this article, we will discuss how to calculate the measurement using jangka sorong and mikrometer sekrup. These tools are essential in engineering and manufacturing fields. By mastering this skill, you can ensure the accuracy of your work and reduce errors. Let’s dive into the details.

What is Jangka Sorong?

Jangka sorong is a measuring tool that is commonly used in mechanical engineering. It is also known as Vernier caliper, and it consists of two scales: the main scale and the Vernier scale. The main scale is fixed, while the Vernier scale is movable.

The Vernier scale consists of ten equal divisions that match nine divisions on the main scale. The tenth division on the Vernier scale is slightly shorter than the others. By aligning the Vernier scale with the main scale, you can achieve accurate measurements even up to 0.05 mm.

Here’s how to read a jangka sorong:

Main Scale	Vernier Scale	Measurement
10 mm	0.48 mm	10.48 mm

Notice that the Vernier scale’s 48th line matches with the main scale’s tenth line. Therefore, the measurement is 10.48 mm.

How to Use Jangka Sorong?

Before using a jangka sorong, make sure that it is clean and free from dust or dirt. Open the jaws and place the object to be measured between them. Move the Vernier scale until it is close to the object but not touching it.

Then, tighten the jaws slowly until they firmly grip the object. Make sure that the jangka sorong is perpendicular to the object being measured. Look at the Vernier scale and record the measurement. Finally, release the jaws and store the jangka sorong properly.

What is Mikrometer Sekrup?

Mikrometer sekrup, or micrometer screw gauge, is another precision tool for measuring small objects. It consists of a calibrated screw and a movable anvil. The screw has a pitch of 0.5 mm or 0.025 mm, depending on the type of mikrometer sekrup.

By rotating the screw, the anvil moves towards or away from the object being measured. The measurement is read from the sleeve and the Vernier scale. The sleeve has a main scale that measures up to 1 mm, while the Vernier scale measures up to 0.01 mm.

Here’s how to read a mikrometer sekrup:

Sleeve	Vernier Scale	Measurement
5.00 mm	0.20 mm	5.20 mm

Notice that the Vernier scale’s fifth line matches with the sleeve’s thirteenth line. Therefore, the measurement is 5.20 mm.

How to Use Mikrometer Sekrup?

Using a mikrometer sekrup is similar to using a jangka sorong. First, clean the tool and make sure that the anvil and the screw are free from dust or debris. Place the object to be measured between the anvil and the screw and tighten the screw slowly until it grips the object.

Look at the sleeve and the Vernier scale and record the measurement. Finally, release the screw and the anvil and store the mikrometer sekrup properly.

How to Calculate the Measurement?

To calculate the measurement using jangka sorong or mikrometer sekrup, you need to add the main scale reading and the Vernier scale reading. For example, if the main scale reading is 10 mm and the Vernier scale reading is 0.48 mm, the measurement is:

10 mm + 0.48 mm = 10.48 mm

If you are using a mikrometer sekrup, you need to add the sleeve reading and the Vernier scale reading. For example, if the sleeve reading is 5.00 mm and the Vernier scale reading is 0.20 mm, the measurement is:

5.00 mm + 0.20 mm = 5.20 mm

FAQ

1. What is the difference between jangka sorong and mikrometer sekrup?

Jangka sorong measures objects up to 150 mm, while mikrometer sekrup measures objects up to 25 mm. Jangka sorong is also easier to use for general measurements, while mikrometer sekrup is more accurate for precise measurements.

2. How do I know if my jangka sorong or mikrometer sekrup is accurate?

You can check the accuracy of your jangka sorong or mikrometer sekrup by measuring a standard object that has a known measurement. If the tool shows the correct measurement, it is accurate. If not, you may need to calibrate or repair the tool.

3. Can I use jangka sorong or mikrometer sekrup to measure angles?

No, jangka sorong and mikrometer sekrup are not designed for measuring angles. You need to use a protractor or other tools for measuring angles.

4. What is the resolution of jangka sorong and mikrometer sekrup?

The resolution of jangka sorong is 0.05 mm, while the resolution of mikrometer sekrup is 0.01 mm.

5. How do I choose between jangka sorong and mikrometer sekrup?

Choose jangka sorong for general measurements and objects up to 150 mm, and mikrometer sekrup for precise measurements and objects up to 25 mm. Consider the accuracy and resolution requirement of your work before choosing the tool.

There you have it, Sohib EditorOnline. With these simple steps, you can master the art of calculating measurements using jangka sorong and mikrometer sekrup. Remember to always clean the tools and store them properly after use. Happy measuring!
