Gyro Sensor
1. Rotation Level : When "Counterclockwise Rotation Level: 1" or higher, and "Clockwise
Rotation Level: 1" or higher are individually detected even once, the
Rotation Level is OK.
2. Sensor Output : When "Gyro Sensor Output Value Judgment" is OK, the Sensor
Output is OK.
3. Variation :
When the OK state of "Variation OK/NG Information" continues for
more than 5 seconds, the Variation is OK.
