Hello, i'm using an ADXL 335. I had weird values when i tried to get the static acceleration on the three differents axes. I have decided to try the Self-test pin by powering the Self-test pin with 3,6 V and 2 V.
I chose those two voltages because results for the Self-test are written in the datasheet for those voltage.
I have great result for 2 V (Ux=82mV, Uy= 98mV and Uz = -190mV)
Theorically i should have Ux = -96, Uy = 9- and Uz = -163.
BUt let's say it's okay
Now when it comes to 3,6V. Instead of having a diffence of voltage when Selftest is off and selftest is on of :
Ux = -560
Uz = 950 mV
I have :
Ux = 150 mV
Uy= 149 mV
Uz = - 294 mV
something is not working and i don't know what. I tried the same experiment with two others ADXL 335 but it was the same problem.
Thank you for your time, hope you can help me
