Here is a photo of my test rig, it uses a small vacuum pump (Parker Pumps) to provide the 'suck' with a simple PWM speed control and water manometer to measure the pressure. It gives a nice steady reading of the pressure required to crack the 2nd stage.

I'm not sure yet about better adjustment but it certainly enables better accuracy. For example I am able to discriminate between two identical Aqualung legend 2nd stages, one measures 7/8" wg and one measures 1" wg. That's 1/8" difference which is 1/16" on each side of the manometer.

I checked all my regs after I finished the test rig and all are within manufacturer's specification so I haven't actually done any adjustments
