The dial indicator is designed to measure linear dimensions by absolute and relative methods, to determine the magnitude of deviations from a given geometric shape and the relative position of surfaces. Indicators with a measuring range of 0-2 mm are available in two versions:
- ICH - with the movement of the measuring rod parallel to the scale;
- IT - with the movement of the measuring rod perpendicular to the scale.
The indicators are mounted either by a connecting sleeve with a diameter of 8h7, or by a lug 5 mm thick with a connecting hole with a diameter of 5 mm.
The use of the dial indicator is quite varied, so it is not described here. Specific cases of using the device are described in the repair manual (for example, measuring the end play of the crankshaft of an engine, measuring the runout of a brake disc, etc.).
