Well that's easy! one question though. Let's say you have a gauge and with no pressure on it, the needle is correctly at zero. But like you said, let's say when testing pressure, it's off by XX lbs. When you adjust that little part (squeeze or open more) and get the right pressure, wouldn't that then make the needle, when no pressure, not be at zero anymore? If so, how do you make it perfect zero at no pressure and accurate when pressure? Just curious.
My issue is the needle is pointing to 16 psi at rest. Need to move it back to zero so I don’t need to subtract every time. I’m haven’t figured out how to move it to zero
Carefully pry the pointer off, set it in the correct position, gently tap it back down onto the shaft. You can probably find a cheap watch hand puller to safely lift it off. 40 years in oil and gas industry calibrating and adjusting meters and gauges. Bending gauge linkage is not the correct way to adjust.
@@joshstrickland986 That's what I was wondering. If squeezing or prying more open that little U thing to get an accurate reading, wouldn't that action also cause a non-zero point when no pressure? Also, what about a gauge that is at perfect zero with no pressure, as it should be, but way off when pressure applied? I don't know if there's a difference with these vintage ones and the new ones. It seems that every gauge I have shows a different pressure (although slightly) than each other, when testing the same tire, but all zero at no pressure just fine. Adjusting the needle wouldn't work on those, I would think, since they are at zero. Ideas??
Welcome back! I didn't realize how easy it was to calibrate the old pressure gauges.
Glad to see you back. Always enjoy your content.
I have that work in my hose
We have the same thing, mine is over 3 psi so I need to spread the U thing a little bit. Thanks for the info 👍🙂
Miss your content. Will you be back???
Awe. Thanks man. And yes sir. Working on a video right now. The Atomic S/MC.

mine is at 16 lbs too,...?
This isn't calibration, it's only adjustment, as you don't know the true reading
