Abstract
The state or setting of an electronically readable wheel counting wheel mechanism is reliably and unambiguously ascertained for each setting thereof, and for this purpose, the counting wheel mechanism is functionally divided into rotating and stationary wheel packets, in dependence on its setting at the instant of the read-out, wherein the first rotating wheel pack comprises the lowest digit counting wheel a as well as the next higher digit counting wheel b, in case the lowest digit counting wheel a is in the setting between 9 and 0 and so forth, with the stationary wheel packet comprising the rest of the counting wheels. In a rotating wheel packet, the indication or setting of a counting wheel is absolutely ascertained from its angle of rotation, with the inclination of the other counting wheels, of a rotating wheel packet, being ascertained through their rotation relative to the absolutely ascertained counting wheel or through the rotation relative to a previously ascertained wheel.
