S01E02 - BELAJAR ALAT UKUR VERNIER CALIPER

Summary

This educational video explains how to use a vernier caliper, covering its parts, functions, and how to take accurate measurements. It provides step-by-step guidance on measuring external, internal diameters, and depths, with detailed instructions on reading the main scale and the Vernier scale. The video also includes tips for proper calibration and reading techniques, ensuring precision in measurements. With clear examples and practical advice, viewers will learn how to measure objects with high accuracy using a Mitutoyo vernier caliper, making this a valuable resource for both beginners and those seeking to refine their skills.

Takeaways

• 😀 Vernier caliper is a measuring tool used to measure external and internal dimensions, as well as depth or height of objects.
• 😀 The Mitutoyo vernier caliper shown in the video has an accuracy of 0.02 mm.
• 😀 The caliper consists of several parts, including the outer jaws for external measurements, inner jaws for internal measurements, and a depth rod for measuring depth.
• 😀 The slider adjusts the jaws to fit the object being measured, while the clamp screw locks the slider in place to prevent movement.
• 😀 The main scale has markings in millimeters and inches, with each line representing one millimeter on the lower scale.
• 😀 The vernier scale is used for reading decimal values, with each line representing 0.02 mm on the scale.
• 😀 When measuring internal diameter, ensure the inner jaws are properly aligned with the object being measured and secure the slider before reading the scale.
• 😀 To read the vernier caliper, first observe the main scale to get the whole number measurement, then find the line on the vernier scale that aligns best with the main scale for the decimal value.
• 😀 For external diameter measurements, the outer jaws should be positioned around the object, ensuring they are centered and properly aligned.
• 😀 When measuring depth, the depth rod should be inserted until it touches the bottom of the object, ensuring proper alignment of the caliper for an accurate reading.
• 😀 Always remember to tighten the clamp screw to ensure the measurement remains fixed and avoid misreadings when taking measurements.

Q & A

What is a vernier caliper used for?

A vernier caliper is used to measure the external and internal dimensions, as well as the depth or height of objects. It is useful for measuring precise dimensions of workpieces.

What is the significance of the 0.02 mm precision mentioned in the script?

The vernier caliper in the video has a precision of 0.02 mm, meaning it can measure in increments as small as 0.02 mm, which allows for highly accurate measurements.

How do you use the outer jaws (OST Angeles) of the vernier caliper?

The outer jaws are used to measure the external dimensions of an object, such as the outer diameter or thickness of the workpiece.

What does the 'Insert jauh' or 'inner jaws' of the vernier caliper measure?

The inner jaws (Insert jauh) are used to measure the internal dimensions of an object, such as the inner diameter or internal gaps.

What is the purpose of the depth bar (debar) on a vernier caliper?

The depth bar is used to measure the depth of holes or recesses in an object. It helps measure the distance from the surface to the bottom of a cavity.

How do you use the slider on a vernier caliper?

The slider is used to adjust the opening of the jaws to fit the object you are measuring. It helps position the caliper for accurate measurements.

What is the function of the clamp screw (klem skrub) on the vernier caliper?

The clamp screw is used to lock the slider in place, preventing it from moving and ensuring that the measurement remains stable during the reading.

What units are used for the measurements on the vernier caliper?

The vernier caliper has two types of units: millimeters (mm) on the bottom scale and inches on the top scale.

How do you read the main scale and the vernier scale?

First, read the value from the main scale, which is marked in millimeters. Then, read the value from the vernier scale to determine the decimal place, with each line representing 0.02 mm.

Can you explain the process of measuring internal diameter with a vernier caliper?

To measure the internal diameter, use the inner jaws of the caliper. Ensure that both sides of the jaws are properly positioned inside the object, then read the measurement on the main scale and the vernier scale.
