Abstract
A gage block set includes a plurality of gage blocks mounted within a case, each gage block having opposed gage surfaces with a nominal dimension therebetween and a known deviation from the nominal dimension. Sensors associated with each gage block sense the removal of each gage block from the case. A signal generator provides a distinct signal corresponding to which gage block is removed from the case. A memory stores the known deviation of each gage block within the case. A control unit responsive to the signal generator addresses and retrieves from the memory the known deviation for each gage block which is removed from the case, combines the known deviation with the deviations of previously removed gage blocks and outputs the total deviation to a display device.
