Abstract

PURPOSE:To rapidly find a fault position in a signal processing circuit without using any special meauring instrument, by comparing signals from plural preset detection positions with a fault detection level. CONSTITUTION:When the mode switch 3 on a console panel 2 is set to (mode 1), a control circuit 5 generates a control signal necessary for fault detection. The detection signal from a circuit whose fault is to be detected is inputted through an analog multiplexer 8 and an A/D converter 9 to a comparator 11, where it is compared with a fault detection level. If a fault is detected, an address value is latched in a latch circuit 16 and a fault code showing the fault position is displayed on a display device 17. Then when the mode switch 3 is set to (mode 2), the latch circuit 16 latches the output of the A/D converter 9 and the voltage value at the detection position is displayed on the display device 17.
