Introduction

This tutorial will guide you through the process of reading a caliper (jangka sorong) accurately. A caliper is a useful tool for measuring the dimensions of an object with precision. Understanding how to use it effectively is essential for various applications in engineering, woodworking, and metalworking.

Step 1: Familiarize Yourself with the Caliper

• Identify the Parts: Understand the main components of the caliper, which include:
  • Main scale
  • Vernier scale
  • Depth rod
  • Inside jaws
  • Outside jaws
• Types of Calipers: Recognize the difference between digital and manual calipers. Digital calipers provide a direct readout, while manual calipers require interpretation of the scales.

Step 2: Measuring Outside Dimensions

• Position the Object: Place the object between the outside jaws of the caliper.
• Close the Jaws: Gently close the jaws until they touch the object without applying excessive pressure.
• Read the Measurement:
  • Look at the main scale for the whole number.
  • Check the vernier scale for the fractional part. The line on the vernier that aligns with a line on the main scale gives the precise measurement.

Step 3: Measuring Inside Dimensions

• Insert the Inside Jaws: Open the caliper and place the inside jaws inside the object (like a hole or tube).
• Close the Jaws: Adjust the jaws until they touch the inner walls.
• Read the Measurement: Follow the same reading method as in Step 2.

Step 4: Measuring Depth

• Use the Depth Rod: Extend the depth rod from the bottom side of the caliper.
• Insert the Rod: Place the rod into the hole or recess you want to measure.
• Read the Depth: Ensure the caliper is resting flat on the surface and read the measurement using the main and vernier scales.

Step 5: Practical Tips for Accurate Measurement

• Zero the Caliper: Before taking any measurements, ensure the caliper reads zero when the jaws are closed.
• Avoid Parallax Error: Always look straight at the scale to prevent misreading values.
• Clean the Caliper: Regularly clean the measuring surfaces to ensure accuracy and prevent wear.

Conclusion

Reading a caliper accurately involves familiarizing yourself with its parts, knowing how to take various measurements, and applying best practices for precision. With these steps, you can confidently use a caliper for your measurement needs. Practice measuring different objects to enhance your skills, and remember to maintain your caliper for long-lasting accuracy.
