- Designed to prevent malfunction due to lightning surge and noise due to built-in mechanical sensor.
- The earthquake indicator (external display panel) can be installed as an option.
- Simultaneously with the occurrence of the earthquake, the instantaneous detection of the magnitude of the shake, continuous display / recording of the maximum acceleration and seismic intensity, as well as the operation of the security device etc. by the external control signal when the set value or more is reached .
- Perform the measurement seismic intensity algorithm calculation process of the Japan Meteorological Agency and display the seismic intensity.
