Adjustment of Measuring Gauge Before Use

Which measuring gauge needs to be set up (adjusted) to a fixed dimension before use?

a) Dial indicator
b) Split-ball gauge
c) Telescopic gauge
d) Feeler gauge

Answer:

The dial indicator needs to be set up to a fixed dimension before use.

The measuring gauge that needs to be set up (adjusted) to a fixed dimension before use is the dial indicator. A dial indicator is a precision instrument used to measure small distances or dimensions with high accuracy. It consists of a needle attached to a dial that displays the measurement in units such as millimeters or inches.

When using a dial indicator, it is crucial to set it up correctly before taking measurements to ensure accurate results. Proper adjustment of the dial indicator involves zeroing the needle at a fixed point or reference position. This calibration step is necessary to eliminate any potential errors that may affect the measurement readings.

By calibrating the dial indicator to a fixed dimension, users can establish a baseline for accurate measurements and reduce the margin of error during the inspection process. This pre-use setup is essential for achieving reliable and consistent results in various industrial applications, such as machining, quality control, and dimensional inspection.

Remember to always follow the manufacturer's instructions and guidelines for setting up and using the dial indicator to maintain its accuracy and prolong its lifespan. Regular calibration and maintenance are key practices to ensure the optimal performance of measuring instruments like the dial indicator.
