How to Use a Caliper: A Comprehensive Guide
Introduction to the Caliper
- The video introduces the caliper, also known as "calibrador obier" or "ped Rey," emphasizing its importance in vehicle repair and tool usage.
- The caliper has been used since the 1st century and consists of two main parts: a fixed rule and a movable slider.
Parts of the Caliper
- The fixed part is a ruler that can be metric (centimeters) or imperial (inches), while the movable part features the Vernier scale for precise measurements.
- It includes external jaws for measuring outside dimensions, internal jaws for inside measurements, and a depth rod for measuring depths.
Measuring Techniques
- When using the depth rod, ensure that only it enters the hole being measured; the ruler should remain outside.
- Some calipers have a locking screw to maintain measurement accuracy after taking readings.
Reading Measurements in Metric System
- In the metric system, each centimeter is divided into 10 mm. The Vernier scale further divides these into 20 sections.
- To determine measurements, combine readings from both the main scale and Vernier scale. For example, if zero aligns with one line on the main scale, it indicates 1 mm.
Example Measurement in Metric System
- If zero does not align perfectly with any line on the main scale, find where any line on Vernier matches with it. This helps achieve accurate readings.
- An example shows how to read 1.5 mm by adding lines surpassed by zero on both scales.
Reading Measurements in Imperial System
- In English units, inches are divided into fractions (16ths), while Vernier scales divide them into eighths.
- Similar principles apply; check if zero aligns with any line on either scale to determine fractional values accurately.
Example Measurement in Imperial System
- An example illustrates how to convert fractions correctly when reading measurements from both scales combined.
Understanding the Bernier Scale in Measurement
Simplifying Measurements with the Bernier Scale
- The discussion begins with simplifying measurements, specifically noting that 332 avos remain after a calculation. The speaker explains how the zero on the Bernier scale has surpassed one inch and one line, indicating a measurement of one inch plus an additional 1/16th.
- The speaker elaborates on calculations involving fractions, multiplying 1/16 by 8 to arrive at a total of 8128. This is then added to another value (6128), resulting in a cumulative total of 14128.
- After simplification, the final measurement is presented as one inch plus 764 avos. The speaker emphasizes clarity in understanding this process and encourages viewers to engage with their content through subscriptions and likes.
