That upside-down 'U' is the accuracy classification- in this case 2.5% of the full scale (20mA). Which is 0.5mA. So it's accurate to within half a mA.View attachment 210003View attachment 210003What does the upside down ‘U’ symbol with the line at thebase mean and what is it warning me about. Is it saying I need a shunt?
I think that is what the 2.5 indicates.That upside-down 'U' is the accuracy classification- in this case 2.5% of the full scale (20mA). Which is 0.5mA. So it's accurate to within half a mA.
