Get Control Accelerometer Test Tool - Version 5.0
If the tool measures earth gravity to +/-0.1g (+/-10%) using the Calibration Display feature, it is working
properly.
To remove the system DC offsets to get a more accurate verification, use a level to improve the accuracy
of each axis measurement. Record each positive and negative axis reading. Then subtract the negative
axis measurement from the positive axis measurement and divide this result by 2. This number should be
close to 1.00g. This method removes the tool’s DC offsets from the measurements. However, it does not
account for geographical earth gravity variances or inaccuracies in orienting the tool perpendicular to earth
gravity.
