Still training so unable to post this in the GSR forum but I don't think it contravenes the no advice about repairs rule, my apologies if I'm wrong.
Question is what's the rational of taking readings over a two minute period for a metric meter when one sweep of an imperial meter can be about 40 seconds?
I am also confused as to why you can get high meter standing pressure readings. Other day I did a tightness test and despite being very slow with the ECV I got nothing on the gauge until the valve was almost fully open at which point it shot up to 29mb, repeated the test moving the ECV at the same rate and it acted quite normally and stopped at 21.5mb. Mentioned it to the engineer I'm working with and just got told it must have been my error. I can't see what I could have done wrong other than locking up the regulator but then isn't the regulator there to prevent such high pressures.
Just find it confusing so if anyone can give me an explanation I'd appreciate it.
