For instance, straightness, flatness orposition errors, such as deviations from parallelism or squareness can be measured.Depending on the type of level, readings may differ. Typical measurement outputs are:• Inclination in / 10 in, respectively in mm / m.• Radians in mrad.• Angle in decimal output, e.g. 12.37°.• Sexagesimal angle in degrees (°), minutes (') and seconds ("), e.g. 15°, 30', 45".Application of two electronic Inclinometersin differential mode for the capture of thesquareness errors on a machine tool.Calibrating a try square using theETALON RA squareness measuringinstrument.I-2Rapp Industrial Sales888 789-7277
