... Sensor Data View 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 ...
