9.1.1.1 Manual Calibration
The i50 orientation can be programmed by setting the “Accelerometer X/Y/Z Angles” using the i50
Programmer. The value zero is reserved for calibration, so use a small value (such as 0.1) instead of
zero when setting values manually. The X/Y/Z angles are measured in degrees relative to the starting
position shown in Figure 8.
Figure 8
– Accelerometer Angles
With all values near zero the i50 orientation has the power connector (on red side in illustration)
facing forward, and top (green side) facing up. The X value increases from zero as the red side
angles down, Y values increase from zero as the blue side angles up, and Z values increase from
zero as the blue side rotates backwards.
If the angle of installation is known then manual adjustment will work well, but automatic calibration
should give more accurate results.
