Abstract

PURPOSE: Inspection of ICs is performed at a high speed and with ease by supplying pulses of high frequency to a time counter through the use of switces used for time adjustment, etc. and hampering of time measurement owing to the supply of high frequency when the watch is dropped or on other occasion is prevented.
