Thanks for your answer but I still don't understand it: offset is a a measured value when nothing is connected example 2048 -> 2042 but what your mean exact with the SENSITIVITY_CORRECTION can you give me an example ? Thanks :)

Hello I Hope someone can help me, I bought a pmod isns20 ... and have a question about the formula in this guide:https://digilent.com/reference/pmod/pmodisns20/reference-manual I dont understand from where does the formula come from -> Ima = 1000/89,95 ..... i dont understand the 89,95 i have read multiple times the Datasheets ( ACC772,adc7476) .... my calculation would be as follows: lsb = 3,3V ( operating voltage) / 4096 ( bit range frome the 12 bit adc) x = read out bit word mv = (x-2048) * lsb *1000 Ima = mv/66 ( sens from the sensor) what is my mistake ? Can someone please help with the formula in the guide ?
