ELECTRONIC TAPE RULE OF THE DISCLSOURE: An electronic extension tape for linear measurement has a tape portion extensible from the housing thereof, the housing containing a position track with electronic reading means adjacent thereto, connected with an electrical processer providing output to a visual readout representing real tape extension, in a first operative state; and in a pre-selected second state utilizing a pre-programmed processer and memory to provide readouts as desired functions of real extension. The processor enables a tab function to be used, in which multiples of a pull-out value are flagged. The processor also permits division of an output value by an integer, so as to read a half value for a real tape extension. The memory also provides an additive function for sequential tape extension values. |
