Scale scale

A scale is used to precisely set one precision mechanical component in relation to another. It is usually only a few centimeters long and a fine ruler , usually made of metal , which is evenly graduated in millimeters or a scale of another scale. Depending on the required accuracy, the reading is carried out free-eyed or with a magnifying glass or vernier .

Examples of short setting scales are the scales on push-off triangles or optical devices, e.g. B. on the focuser of an astronomical telescope, on the measuring table of a microscope or on the guide rods of a bellows device . They can also be provided with a fine drive or clamping screws , e.g. B. for adjustment on measuring instruments. Longer scale scales can be found on drawing devices or the coordinateograph .
