Abstract
Abstract A fuel dispensing system is provided with an indicator verification system for confirming the operability of segmented numeral indicators comprising a control unit operable between ON and OFF positions; synchronizer logic circuitry for sequentially visualizing and blanking all segments of the segmented numeral indicators and a timer circuit for programming the operation of the synchronizer circuit. The control unit is operatively connected to the synchronizer logic circuitry and to the timer circuit for activating the synchronizer to visualize all segments of the indicators and initiate operation of the timing circuit upon operation of the control means to its ON position. Timed interval operation of the timer circuit automatically terminates full segment visualization, initiates and terminates blanking of the indicators, resets the counters of the fuel dispensing system and conditions the fuel dispensing system for dispensing fuel. Upon completion of the fuel delivery, operation of the control unit to its OFF position initiates recycling of the verifying sequence followed by termination of the indicator display readout after an appropriate time interval.
