You have a very old service manifold and the high-pressure gauge on this service manifold set has a continuous scale, calibrated to read from 0 to 500 psig. true or false.

That statement is FALSE

the scale that calibrated to read from 0 to 500 is usually the standard used by the new kind of service

the older one usually only take up to 340

hope this helps
