Hi,
I have technical question again regarding the ADXL357 self test mode because there's not much info about it.
I have enabled the self test mode by writing 0x03 to its self test register (0x2E) and read its Z-axis output.
Below is the test result from our previous PCBA build for 9 sets of ADXL357.

ADXL Self Test (Z-axis @ 10G) |

1.711 |

1.394 |

1.793 |

6 |
0.835 |
|
7 |
1.234 |
|
8 |
1.474 |
|
9 |
0.899 |
Comparing the above result with the datasheet specification, can I say that only 2 out of 9 are passed the test?
Or is there something else that I have missed out during setting up the device prior for self test mode.
