Background

Dimensional metrology is the science of measurement to quantify the size of the objects and help to decide whether the manufactured part is accepted or rejected as per the drawing and tolerance. Even though the person is able to take the reading, the measuring error may happen due to the improper handling of the instruments. So one must be good in selection of the right instrument, handling and reading the measurement.

Key Takeaways

• Develop awareness, knowledge and skills necessary for the reliable measurement application / assessment of measurement quality
• Evaluate correct measuring methods / comparative measurements
• Errors in the instrument
• How to read the measured value
• Handling of the measuring instrument
