Abstract

PURPOSE: To judge the goodness or not of the voltage values including feed systems extremely meticulously by detecting the deviations of the supply voltage within an electronic apparatus on the load side and subsequently tracing the results of the detection with a voltage diagnosis micro-diagnose.
CONSTITUTION: A service processor 23 is connected to an arithmetic control part 24, channel control part 25 and memory device control part 26 respectively having DC power sources 19 thru 20 and each information is displayed in a console display 22. At the time of diagnosing the voltage VF of the DC power source 19, it is compared with the reference voltage sources 35, 36 by the comparators 37, 38 of a voltage package 27 is applied to an AND circuit 40 together with control bus L1 via OR circuit 39, the output whereof is then returned to the service processor 23 and is thereby processed. Thus, by so forming the micro-diagnose as to perform the diagnosis of voltage and the diagnosis of the logic parts, the goodness or not of the voltage values may be diagnosed extremely meticulously.
