G Sensor
Display of G Sensor Inclination Level
The value obtained by converting the acceleration (X axis) [m/s^2] acquired from
the GNSS information into the inclination angle [deg] and dividing the level is displayed.
The inclination angle [deg] = asin (the acceleration [m/s^2] / 9.80665[m/s^2]) * 180.0[deg] / Pi
The relationship between level and tilt angle is as follows.
Upward inclination Level 3
Upward inclination Level 2
Upward inclination Level 1
*****
10.0 > Tilt angle -10.0
Flat
Downward inclination Level 1
Downward inclination Level 2
Downward inclination Level 3
Sensor Output
It displays the following values obtained from sensor information for X axis, Y axis and Z axis.
Acceleration sensor AD value
Determination of output value of Acceleration sensor
0x0
: NG
Other than 0x00 : OK
Variation
It displays the following values obtained from sensor information for X axis, Y axis and Z axis.
Acceleration sensor dispersion value
Variation OK/NG information
0x05 or 0x06
: OK
Other than those above : NG
Description
Tilt angle 30.0
30.0 > Tilt angle 20.0
20.0 > Tilt angle 10.0
-10.0 > Tilt angle -20.0
-20.0 > Tilt angle -30.0
-30.0 > Tilt angle

Inclination Level, Sensor Output and Variation
[OK Judgment] When all of the following three items are OK, the inspection result is OK.
1. Inclination Level : When "Upward Inclination Level: 1" or higher, and "Downward Inclination
Level: 1" or higher are individually detected even once, the Inclination
Level is OK.
2. Sensor Output :
When "Acceleration 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.
