Apm mini v3.1, accel calibration failed

Hi everyone, I am new to the forum as well as using the apm board, I recently bought a new board(apm mini 3.1) And i am having difficulty setting it up. Every time I go to calibrate the accelerometer it says calibration failed. Does anyone have any ideas of what I could try to fix this problem? Thanks for your help!

It is rare for accel calibration to fail. Make sure you follow the instructions to the letter and that the APM is correctly oriented (arrow pointing forward). If you never get a successful accel calibration, I suspect you have a bad APM and shoudl return it.
