Abstract
PURPOSE:To obtain a simple and inexpensive device by comparing a current flowing to a system with a current at the time of normal state stored in advance. CONSTITUTION:When a system power source is turned ON, timer relays T1-Tn start operating, and powers are supplied to components I1-In after t1-tn sec. The currents flowing to the system alter to i1', (i1'+i2')-(i1'+i2'+...in') after t1-tnsec. A current measuring means 1 measures a current flowing to the system. Malfunction current discriminating means 2 reads current values i1-in flowing at the time of normal state of the components I1-In stored in advance in a component current table 3, compares them with current values i1', (i1'+i2')...(i1'+i2+...in') measured by the means 1, and displays the trouble of the component in which the malfunction occurs through malfunction device display means 4 in case of judging the malfunction. Accordingly, the trouble of the components can be monitored merely by measuring the current at one place.
