Abstract
A manual device for the detection of photometric values on a printed product comprises a measuring head extruding from a housing into a measuring position. The measuring head is mounted together with its optical components on a measuring carriage, which may be displaced along the bottom of the housing by means of a drive motor between a rest position and a measuring position. The drive motor drives via a gear, a drive pulley and a grid axle for a monochromator. A sliding gear and a locking device are coordinated with the drive pulley, with the locking device immobilizing the measuring carriage precisely in the measuring position. The drive motor serves to displace the measuring carriage until the locking process essentially begins; and after this process, serves to rotate the grid axle.
