As described above, according to the present invention, since the reference signal is input instead of the pressure sensor by operating the external operating member, it is possible to easily check the circuit configuration. Since no special equipment is required to check the pressure sensor circuit, it is particularly effective for small portable devices. For example, in watches that are configured to measure water depth using a pressure sensor, the water depth function is a life-threatening issue, and it is extremely effective to be able to easily check and confirm it using an external operation before diving. It is. Furthermore, in the configuration of the present invention, as described above,
