Abstract
PURPOSE: To decide on whether the functions of an electronic watch are normal or not, by comparing the information of module to be measured with that of a standard module, display segment by display segment.
CONSTITUTION: Module 1 to be measured and standard module 2 are applied externally with the same reference frequency to synchronize both the modules completely and control signals S1WSn are sequentially applied to analog gates A1W An to store segment signals in shift registers 7 and 8. The memory contents of shift registers 7 and 8 are outputted in sequence by keeping on applying clock pulse ϕ, and exclusive-OR gate 9 detects coincidence or dissidence between measured module 1 and standard module 2.
