I use FXAS21002CQR1 gyro ic in my project. In order to perform tests I use its self-test function. But often it gives an error (the obtained value is lower than 6000). FXAS21002 top marking is "263 F2102 NCIA". Are there any tricks to successfully use the Self-Test function. And one more question: can the Self-Test function be used only at 25'C or also at full work temperature range?
