Abstract
For a display device with scale (4), pointer (5), stepping motor (1), gearing (2) and control means (7) in which a plurality of revolutions of the stepping motor (1) corresponds to the entire display range and the control means (7) contains a step counter with reversibly unambiguous association of number of steps and display value, a possibility for the continuous adjustment of the step counter (1) with the actual pointer position is created by a coding disk (3) which is connected, fixed for rotation, with the shaft (6) of the pointer (6). The disk has a number of markings (9) arranged at different distances apart on its periphery and having a sensor (8). By a comparison of the actual number of steps with a reference number of steps stored in a table for each of the markings (9), it can be determined whether the association between number of steps and pointer position is correct or must be readjusted.
