The EDMU is below, to show the Reg pressure.  The barrel is 600mm ST…….FX Impact .25, purchased Nov. 2016, with a second barrel in .30.  When I’m done tuning for both 25gr and 34gr .25 pellets, the EDMU will be replaced with the FX gauge. I will record the FX gauge and equivalent EDMU pressure readings so I can adjust reg pressure without swapping gauges.  Then the EDMU can do it’s thing with the bottle pressures up front.

I was surprised to learn the difference between the FX gauge on the bottle (just under 150 bar), and the off regulator pressure of 111 bar.  When I filled the bottle to 220 bar, the EDMU,at the reg, rose and stopped at the factory setting of 132 bar.

I’m not concerned with the FX gauge not reading the same as the EDMU, as long as I know the equivalent.

Regards,

John

ps.  then I get to do it again, for the .30…….fun
