MACAM ALAT UKUR dan Cara Membaca Jangka Sorong Ketelitian 0,02 & 0,05 mm

Introduction

This tutorial provides an overview of measuring tools, specifically focusing on the caliper, also known as a jangka sorong, and how to read its measurements accurately. Understanding how to use a caliper with precision can greatly enhance your measuring skills in various fields such as engineering, woodworking, and metalworking.

Step 1: Understanding the Types of Calipers

• Digital Calipers: These provide a digital display, making them easy to read. They often have higher precision.
• Vernier Calipers: These use a sliding scale and require more skill to read accurately but are more common in workshops.
• Dial Calipers: Similar to vernier calipers but with a dial indicator for better readability.

Practical Tip

Choose the type of caliper based on your needs. For precision tasks, a digital caliper is recommended.

Step 2: Components of a Caliper

• Main Scale: The primary measuring scale, usually in millimeters or inches.
• Vernier Scale: A secondary scale that slides along the main scale for finer measurements.
• Locking Screw: Used to lock the caliper at a certain measurement.
• Depth Probe: A rod that extends from the caliper for measuring depth.

Common Pitfalls

Ensure the caliper is zeroed before taking measurements to avoid inaccuracies.

Step 3: Measuring with a Caliper

1. Open the Caliper: Slide the movable jaw to open the caliper to the desired measurement range.
2. Position the Object: Place the object between the jaws, ensuring it is snug but not overly tight.
3. Close the Jaws: Gently close the jaws until they contact the object.
4. Lock the Measurement: Use the locking screw to hold the measurement.
5. Read the Measurement:
   • Look at the main scale for the whole number.
   • Check the vernier scale to find the precise measurement up to 0.02 or 0.05 mm.

Practical Advice

Practice reading the scales to increase your familiarity and accuracy.

Step 4: Calibration and Maintenance

• Calibration: Regularly check your caliper's accuracy against a known standard. Adjust if necessary.
• Cleaning: Keep the caliper clean and free from debris to ensure smooth operation.
• Storage: Store calipers in a protective case to prevent damage.

Real-World Application

Using a calibrated caliper can significantly enhance the quality of your projects by ensuring precise measurements.

Conclusion

Understanding the various types of calipers and how to read them accurately is essential for precise measurement in technical fields. Regular calibration and maintenance of your tools will help you achieve consistent results. For further practice, consider measuring different objects and comparing your results with known measurements to build your confidence and skill.
