FX FX Crown MkII regulator testing

[SilentSquirrel]

Good morning
Here is another FX Crown MkII question.

I would like to know how to test (& measure) the output of the regulator, please.
Preferably while it is installed in the receiver.
Experienced help appreciated.
Thanks
Edward

I read the regulator pressure from its gauge under the gun. Recall one gauge is the bottle pressure and the other is regulator.

 

[SilentSquirrel]

Yes,
However, what I need to do is verify that the gauge and the actual output match.
Put another way
I need to know whether the pressure indicated on the regulator gauge is actually the psi getting in behind the pellet.

I would just get another gauge and swap it in to see if it agrees. I don’t know of a less invasive or less expensive way of doing it.

FX Crown setup.
.177
FX Pellet 12.5 gr
REG Pressure 114 - 115 Bar
Power wheel setting 1,5,10,15,20,23
Bottle pressure 250 Bar
There may be a slight variability in the testing as it was conducted over several days.
The test was standard deviation of Feet per second between a stock regulator, post regulator polish and post HUMA-Air gen 3 regulator install.
