Sorry if this question appears twice as I posted and it never seemed to show up on the question list.


New to PI - I can create most basic tags


I have a question about Raw Scale *MaxRaw and MinRaw".   I know how to convert maxraw 20000 and minraw 4000 in to a conversion factor of 16000 and Dzero 4000.   but that is all I know about that section.


Today our engineer sent me 4 new tags to create and the minraw is negative 2000  (-2000) and the maxraw is 8000.   and honestly I am having a hard time to wrap my head around it because according to SIRI -2000 minus 8000 =  10,000 and if I set the dzero= -2000 then ya it gives me a number but I don't trust my thinking on this one.


Any advise on how to do this with negative numbers?
