Abstract

PURPOSE:To check a device without lowering a reliability of a device to be checked, by multiplying an input signal by a selected constant, changing a constant in order and multiplying it when a command for starting a test has been given, and deciding its result by a deciding device. CONSTITUTION:A process signal PCI is inputted to a multiplier 3 through an inputting circuit 1 and a decoder 2. The multiplier 3 multiplies an input signal by a constant by a setting signal 4a from a setting device 4, and its output signal is provided to a controller CT5. A signal 5a of a result of processing by CT5 is outputted to the outside though a switch 6, and also is provided to a deciding device 7. The deciding device 7 decides the signal 5a in accordance with a signal 8a of a start switch 8, and turns on an indicator 9 and an indicator 10, when its result is normal and it is abnormal, respectively. When checking CT5, the setting device 4 outputs the signal 4a by the signal 8a, increases in order a constant of the multiplier 3, changes it, outputs the signal 5a, and decides it by the deciding device 7. In this way, it is unnecessary to provide a switching circuit on the input side of CT to be checked.
