Abstract
PURPOSE: To make easy the judgement of failed memory element, by informing the state of progress of check for each memory element with the number corresponding to the progress state.
CONSTITUTION: When the switch 4 is applied, the processing section 2 sequentially reads out the memory check program from the memory 3, writes in arbitrary data sequentially from the initial address of the memory element 11, the content is readout and the agreement of the both is checked. At the start of check, the display unit 5 is illuminated and it is distinguished at memory normal state. The memory elements are similarly and sequentially checked. Further, at failure of memory element, the number corresponding to the element number is illuminated on the display unit 5, and the number of times can tell the operator the failed memory element.
