AGEING INDICATION CIRCUIT BY COUNTER

摘要

An aging time display circuit using a counting unit is provided that recognizes and displays an aging time lapse according to the output signal from the counting unit when the aging time exceeds a predetermined time. The aging time display circuit using a counter includes an oscillating unit(10) having a timer IC(5) and outputting a clock pulse; a counting unit(20) for counting the clock pulse of the oscillating unit to judge whether an aging time has lapsed; and recognize/display unit(30) for recognizing the aging time lapse according to the output from the counting unit.
