I just got a deluxe IP gauge from DGX. Tested my two older MR22 Abyss 1st stages and found the IP was high:
One was reading 150psi and the other 155psi.
The specs from Mares is 142-148psi
I adjusted the first stage by loosening the regulating nut with a 10mm Allen key.
When purging one of the 2nd stages the IP will drop and then the needle will indicate between 140 and 145 and then over a couple of seconds it will arrive at just below 150 (148?) and stop. The gauge markings are in 10psi increments.
I left the regulator pressurized with the IP gauge attached for about 10 minutes and did not observe any further change. The IP gauge behaves similarly on both 1st stages.
Since I am new to using an IP gauge and reg maintenance, is it safe to assume this is normal behavior for the older MR22 Abyss 1st stages or should I consider there is a problem and rebuild them?
