Is there a way to calibrate accelerometer on C-boards?
I have two identical C-boards programmed to calculate and log average RMS every 10 minutes on ZTE Android phone that Eric helped me to set up.
I've noticed that the boards are showing different averages. To test how different they are I've placed them both next to each other on the table with brand new batteries installed for about 8 hours. After I retrieved logs the numbers fluctuated from 571.777- 574.402 on the first and 519.714 -522.156 on the seconf. Also the first one was missing one data point. It is almost 10% difference. Hence the question: is it possible to calibrate boards so they show same range of numbers?
