Cara Pengukuran Jangka Sorong

>Hello Sohib EditorOnline, in this article, we will discuss the proper way to measure with a caliper, or jangka sorong in Indonesian. This tool is commonly used in industries such as automotive, engineering, and manufacturing. We will cover everything you need to know about measuring with a caliper, including its types, parts, and how to read it accurately.

What is Jangka Sorong

Jangka sorong is a precision measuring tool that is commonly used in industries to measure the dimensions of an object from the inside or outside. This tool is also known as a caliper, and it comes in different types and sizes. The main function of a jangka sorong is to measure the distance between two opposite faces of an object with high accuracy.

In general, there are two types of jangka sorong – the vernier caliper and the digital caliper. The vernier caliper uses a vernier scale while the digital caliper uses an electronic display. Both types of caliper are used to measure the same things but have different ways of reading and have their distinct advantages and disadvantages.

The Parts of Jangka Sorong

Before we learn how to measure with a jangka sorong, we must first understand its parts. A jangka sorong consists of several parts, including:

Part	Description
Upper Jaw	The part that is used to measure the outside dimension of an object
Lower Jaw	The part that is used to measure the inside dimension of an object
Scriber	A pointed tool used to mark the object being measured
Depth Measuring Blade	It is a blade fixed at the bottom of the lower jaw, that can be used to measure the depth of a hole.
Main Scale	A scale marked in millimeters or inches that is used to give an approximation of the measurement
Vernier Scale	A secondary scale that shows the measurement with greater accuracy

How to Measure with Jangka Sorong

Now that we understand the parts of a jangka sorong, let’s discuss how to measure with it accurately. The following steps will guide you on how to use a vernier caliper:

Step 1: Clean the Jaws and Object to be Measured

Make sure the jaws of the jangka sorong are clean and free from debris. Also, ensure that the object to be measured is clean and free from any dirt or debris that could affect the accuracy of the measurement.

Step 2: Close the Jaws around the Object

Close the jaws of the jangka sorong around the object to be measured. Ensure that the jaws are in contact with the object and that there is no gap between them.

Step 3: Read the Main Scale

Read the main scale value that aligns with the top edge of the upper jaw. Note the value down.

Step 4: Read the Vernier Scale

Read the vernier scale value that aligns with the main scale. Note the value down.

Step 5: Add the Main and Vernier Scale Values

Add the main and vernier scale values to determine the final measurement of the object.

Tips for Measuring with Jangka Sorong

Here are some quick tips that you can follow to get accurate measurements with a jangka sorong:

• Always keep your jangka sorong clean and free from debris.
• When using a digital caliper, always check the battery level to ensure that it is fully charged.
• Be gentle when closing and opening the jaws of the jangka sorong to avoid damaging the tool.
• Always read the measurement from the correct scale on the jangka sorong.

FAQs:

1. How much does a jangka sorong cost?

The cost of a jangka sorong can vary depending on the type, size, and quality. Vernier calipers are generally cheaper than digital calipers, with prices ranging from IDR250.000 to IDR1.000.000, while digital calipers can cost IDR500.000 or more.

2. How accurate is a jangka sorong?

Jangka sorongs are designed to be accurate within one-tenth of a millimeter, or in some cases, one-thousandth of an inch. However, the overall accuracy of the jangka sorong may vary depending on the quality of the tool and the user’s skill in taking measurements.

3. Can jangka sorong measure angles?

No, jangka sorongs are not designed to measure angles. However, there are other tools such as protractors that can be used to measure angles.

4. How should I store my jangka sorong?

When not in use, it is recommended to store your jangka sorong in a dry, cool place, away from direct sunlight or heat sources. You can also use a protective case or cover to protect the tool from dust and debris.

5. Can a jangka sorong be used to measure depth?

Yes, a jangka sorong can be used to measure depth. For this purpose, use the depth measuring blade located at the bottom of the lower jaw to get accurate depth measurements.

Conclusion

Measuring with a jangka sorong is a crucial skill for professionals in various industries. By following the steps and tips outlined in this article, you can get accurate and precise measurements to ensure that your end product meets the desired specifications. Remember to always clean and maintain your jangka sorong, and store it properly when not in use.
