[#PMOD ISNS20 Question about formula]

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 :) 

[#PMOD ISNS20 Question about formula]

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 ?
