Introduction

This tutorial provides a comprehensive guide on how to use a caliper (jangka sorong) effectively. We’ll cover its functions, parts, and the correct way to read measurements. Understanding how to use a caliper is essential for precise measurements in various fields, including engineering and woodworking.

Step 1: Understand the Parts of a Caliper

Familiarize yourself with the main components of a caliper to use it effectively.

• Main Scale: The fixed part of the caliper, usually marked in millimeters or inches.
• Sliding Jaw: This part moves along the main scale to measure the object.
• Vernier Scale: Located on the sliding jaw, this scale helps take more precise measurements.
• Depth Probe: A small rod that extends from the bottom of the caliper to measure depth.
• Inside Jaws: Used to measure the internal dimensions of an object.
• Outside Jaws: Used to measure the external dimensions of an object.

Step 2: Learn the Functions of a Caliper

Understand the different functions and how they can be applied in measurements.

• External Measurement: Use the outside jaws to measure the width or diameter of an object.
• Internal Measurement: Use the inside jaws to measure the internal dimensions, such as the inside diameter of a pipe.
• Depth Measurement: Use the depth probe to measure the depth of holes or grooves.
• Step Measurement: Some calipers have a step feature to measure the height of steps or ledges.

Step 3: Using the Caliper Correctly

Follow these steps for accurate measurements.

1. Ensure Calibration: Before use, make sure the caliper is zeroed. Close the jaws completely and check if it reads zero.
2. Choose the Right Measurement Type: Decide whether you need an internal, external, or depth measurement.
3. Position the Object: Place the object between the appropriate jaws of the caliper.
4. Take the Measurement:
   • For external measurements, close the jaws around the object.
   • For internal measurements, insert the inside jaws into the object.
   • For depth measurements, insert the depth probe into the hole.
5. Read the Measurement:
   • Look at the main scale first to get the primary reading.
   • Then, observe the vernier scale for the additional decimal places.
   • Combine these readings for the final measurement.

Step 4: Reading the Results Accurately

Learn how to interpret the measurement correctly.

• Main Scale Reading: Note the last whole number before the zero of the vernier scale.
• Vernier Scale Reading: Identify which line on the vernier scale aligns best with a line on the main scale. This gives you the decimal part of the measurement.
• Combine Both Readings: Add the main scale reading and the vernier scale reading to get the final measurement.

Conclusion

Mastering the use of a caliper can significantly enhance your measuring accuracy in various applications. Remember to familiarize yourself with its parts, functions, and how to take and read measurements properly. Practice using the caliper on different objects to improve your skills.
