Abstract

PURPOSE:To easily detect the function deterioration and the abnormal operation of an amplifier by selecting an electric signal from a test signal generating section with the operation of a control section, outputting the selected signal to an amplifier side, using a comparison section to detect the output of the amplifier and to compare it with a predetermined reference value. CONSTITUTION:An electric signal is inputted from an input section 10 to a selective section 3, and the selective section 3 outputs the electric signal from the input section 10 to amplifiers 71, 72 through an output section. When a control section 12 is operated at an abnormality inspection, an electric signal from a test signal generating section 11 is selected by the selective section 3 and outputted to the amplifiers 71, 72. Comparison sections 14, 15 detect the output of the amplifiers 71, 72 together with the operation and compare it with a predetermined reference value, and when the detected value is lower than the reference value, e.g. for a prescribed time, an abnormality detection section 16 is energized, and in the case of the abnormality, a notice section 19 is energized and the abnormality display is implemented. Thus, the function deterioration or the abnormal operation of the amplifiers 71, 72 is easily detected.
