Question

Accepted Answer

Auxiliary gauges are used to measure additional parameters while variable gauges are used to measure the same parameter at different points.

Auxiliary gauges are used to measure additional parameters such as temperature, pressure, and humidity.
Variable gauges are used to measure the same parameter at different points, such as the diameter of a cylinder at various points.
Auxiliary gauges are not essential for the main measurement process, but they provide additional information.
Variable gauges are essential for ensuring that the measured parameter is within the required tolerance range.
Examples of auxiliary gauges include thermometers, barometers, and hygrometers, while examples of variable gauges include bore gauges, snap gauges, and plug gauges.
