it's a micromatic , this model http://www.micro-matic.co.uk/part-pid-090039.html
the instruction booklet is rubbish, but as far as i can tell the dial in the middle sets the outlet pressure, but whichever way i turn it, and whether the keg is pressurised or vented the dial on the outlet gauge is at 12 o'clock and doesn't budge. i expected that for a vented keg it would be at zero and i could then turn the dial to the desired psi.
has anyone else got one of these? am i missing something obvious or have i got a duff regulator? i've turned the gas off at the cylinder now and the needles on both gauges haven't budged.
i've spent hours planning and building the bugger and i can't get any beer out of it! mightily frustrating.
