9.9.3. Accelerometer Calibration
Step 1
Step 2
Before leaving the factory every unit has been carefully tested and calibrated. Usually you don’t need to perform a
calibration of the accelerometer during use. However, in some specific cases, we’d suggest you re-calibrate the
accelerometer to obtain better performance, these include special conditions such as temperature changes those will
probably cause the mechanical characteristics changes of the sensor. The calibration should be done on a horizontal
desktop, follow the steps below until all of the 6 different orientations have been completed successfully.
Connect the A3S3 to the PC, open the software and go to the “Sensor” tab, click the “Calibrate” button to
enter the calibration procedure.
Put the gyro on the table with the sticker on top and fix it with your fingers, then press “Next” to continue, the
calibration of each step will take about 2 seconds, during calibrating, the LED will blink blue several times and
then light up solid in blue. Don’t move the gyro until the calibration is done.
