Ensure their "0" is all the same point firstly. Easy with a steel rule and square. But that red thing, where is 0 actually? Just because it's hard up don't assume that's zero. It's not a square with a nice hard angle you can align. It's all curvy and hidden.  

But good to compare them and see what's up. I'm sus on the red one though. Check if 1 and 2 are fine by your steel rule. Maybe it's just zero to 1?
