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.
ID
ADXL Self Test (Z-axis @ 10G) g
1
1.719
2
1.711
3
1.394
4
1.793
5
1.241
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.
