Abstract
An odometer that employs a pulse generator, the pulses of which correspond to a given increment of linear distance. It has a correction circuit which may be set to either add or subtract a pulse after a predetermined number of pulses have been counted. This corrects the linear distance measured for any cumulated total. Consequently, inaccuracies in the dimension represented by each pulse will be periodically compensated for by the added or deleted pulse.
