Abstract
PURPOSE: To confirm the working of the process circuit without applying the mechanical vibration to the seismic sensor, by switching the seismic sensor to the voltage generating circuit by a change-over circuit and then actuating the process circuit by the output voltage of the voltage generating circuit.
CONSTITUTION: The output according to the earthquake is applied to the filter circuit 4 via the change-over switch 2 and then compared with the reference voltage through the comparator 6 after shaping of the waveform. And the output relay 7 is energized by the output of the comparator 6. When the confirmation is desired in the normal state for the working of the process circuit, the switch 2 is turned to the terminal (b). The voltage generating circuit 8 is connected to the process circuit 3 with the relay 7 energized. In such way, the working can be confirmed for the circuit 3.
