4.1
To accurately map the output of the MMA7260QR2 accelerometer to the “Raw Data” applet in the Triax
application while the SRB is laying flat, the raw values should read approximately 0,0 for the X and Y
axes. This is because the SRB is not moving in either axis. However, the Z axis should read
approximately 1 because gravity is pushing down on the device at approximately 1g. If a user were to stand
still while holding the SRB flat (component side up) gravity would be pushing down on the accelerometer
and the user should see the Z axis value at approximately 1g. Users can turn the SRB upside down
(component side down) and the accelerometer Z axis value should be approximately -1g.
