hi Paulina

Which ones are temperature offset, which are constant errors!

if constant errors than us use software calibration.

and do you detail test report ? 

we want to detail review the report.

may we can save the error!

Hi Jaures,

The values showed in the image are constants errors for the temperature and voltage range mentioned on each one of them.

In regards to the test report, unfortunately, we do not have that document or information to provide. I apologize for the inconvenience that this may cause.

Have a great day, 

Paulina
