ABSTRACT:
A digital linear measuring device includes a housing, a reel located within a housing and a measuring tape wound on the reel. The measuring tape is extendable through an opening in the housing as the reel is rotated. An incremental measuring means is associated with the reel for generating incremental measuring data and an absolute measuring means cooperates with the measuring tape for generating absolute measurement data as the measuring tape is extended. A processing unit is responsive to both the incremental measurement data and to the absolute measurement data for generating output reflecting linear extension of the measuring tape from the housing, and a display is responsive to the processing unit for displaying information reflecting the linear extension of the measuring tape from the housing.
