Making sensor settings
Use the supplied calibration chart of the accelerometer you intend to use, and
make the sensitivity setting by performing the following steps.
1. From the [Analog Input] menu screen, select [Sensor Selection] and
then [PV-57I] or [Other].
2. Set [Sensitivity] to the sensitivity value given on the calibration
chart.
Note
When selecting [PV-57I], a popup window appears,
asking whether you want to change the sensitivity
setting. Also note that the factor cannot be changed.
