: Hi Rex, sorry I couldn't get through to you direct
: The rig runs (from supply end)
: supply-regulator-gauge-shutoff-coupler to cyl.
: Close shutoff
: Set pressure to 100 with regulator
: Connect to cyl.
: Open shutoff
: The reading will change right away so no more than a couple of seconds
:is necessary. Keep checking the 100psi setting between tests it can fluctuate
:as your compressor kicks in or other shop tools are used. If you can't get
:100psi lower is OK you just have to do the math to arrive at the % leak
: (pressure difference/original pressure)*100
:
: I'm all for making the process as idiot resistant as possible hence
:the 100psi. Hope this helps.
