It looks to me, that is where it's supposed to be. Each fat line is 500 and the thin ones are 100. If you imagine the last 2 lines, thats just about where the needle is. Tom
Not sure what caused it.....(never been over 3k). Strange enough it catches up around 1,300-1,500psi and is accurate on up to my 2800psi fill. I verified off my JoeB SCBA, and another fill station.
