Which one is more accurate? I have been using AL80 usually filled to 3300PSI tank, at this pressure, SPG and AI reading agree. My SPG is backup, so I hardly look at it.
Yesterday, I use a LP steel tank. Not sure what is the correct fill pressure. But my SPG read 2500psi, but AI read 2200PSI. I think at lower pressure, one of these device is not reading correct.
So, which one is usually more accurate? I will borrow another SPG for compariosn tomorrow, but let's say if the analog is off, I know it can be adjusted. But if the AI is off, can I adjust or calibrate it myself?
