PSI produced by the Airmatic compressor?
I have three pumps I want to check the condition/output of, i.e. two P-3277s, one brand new and one with an few hours on it and one Chinese Arnott, the number of which can’t remember which is about four years old.
I have set up a pressure gauge I can screw into the outlet.

If you are confused because the reading is in bar, one bar equals about 15 psi.
I would not plug the output with a gauge to measure pressure. The pump will very quickly rise to its maximum and then do something, I don't know what, bleed off the excess via a relief valve? Simply pound away? Maybe do it with your Chinesium compressor, but I would not risk the valuable AMK compressors. This could well be destructive testing.
