Abstract
Surface texture measuring apparatus includes a measurement arm table storing mass of an entire measurement arm, an arm length from a supporting point to a stylus, and a horizontal and vertical barycenter of the measurement arm in a horizontal posture for each type of the measurement arm in which a second measurement arm having a different mass is attached; a measurement arm specifier; an inclination angle detector detecting an inclination angle of the detector; and a controller reading out from the measurement arm table the mass, the arm length, the horizontal barycenter, and the vertical barycenter for a specified measurement arm, calculating a difference between a measurement force of the measurement arm in the horizontal posture and a measurement force of the measurement arm in an inclined posture based on the read-out information and the inclination angle detected by the inclination angle detector, and adjusting a measurement force.
