A position-measuring device includes a code carrier having a first graduation track and a second graduation track, the second graduation track being an incremental graduation track. A first detector system is configured to scan the graduation tracks so as to generate first position signals. A second detector system is configured to scan the second graduation track so as to generate second position signals. A first position-processing unit is configured to process the first position signals so as to yield a first absolute position value. A second position-processing unit is configured to process the second position signals so as to yield a second absolute position value. The first position-processing unit is configured to feed an absolute auxiliary position value to the second position-processing unit. The second position-processing unit is initializable with the absolute auxiliary position value.
