Master Setting Disk Gage

A Master Setting Disk Gage is a type of inspection gage used in precision measurement and layout tasks. It is typically used to set or calibrate other measuring tools, such as micrometers or dial indicators, to a known reference dimension.

The Master Setting Disk Gage consists of a flat, circular disk made of a high-precision material, such as steel or ceramic. The disk is carefully machined to have a specific diameter, which is known as the reference dimension. This reference dimension is typically measured and certified by a calibration laboratory to ensure its accuracy.

To use a Master Setting Disk Gage, the user places the disk on a flat surface and brings the measuring tool to be calibrated into contact with the disk. By comparing the measurement obtained from the tool with the known reference dimension of the disk, the user can determine if the tool is properly calibrated or if any adjustments need to be made.

Master Setting Disk Gages are commonly used in industries such as manufacturing, engineering, and quality control, where precise measurements are critical. They are an essential tool for ensuring the accuracy and reliability of other measuring instruments.
