Abstract
A bindery caliper is provided in the form of a non-contacting capacitive change measuring device capable of determining the page count of a multi-page stack with high sensitivity. The capacitance of a pair of plates between which the stack of pages is disposed sets the frequency of an oscillator which is sampled for a predetermined time period. The sampled pulses are counted and compared to a standard within tolerances, and the comparison determines whether the page count is satisfactory. Means for updating the standard value on the basis of accumulated measurements is also provided.
