Is the precision gauge out of scope?
Not necessarily, usually have a full range of 130%, which is over pressure capacity, but also overload capacity, it is best to clear it up, and then open to see if it is still excessive, if you still have to contact the manufacturer.
Not always。 Beyond possible, not damaged. Excess may cause errors in the pressure gauge.
General production is playing margin, not slightly beyond the damage. Basically, the higher the precision, the less the margin.
