well you were right saying it could measure any vacuum.. as thats what it does but usually for inlet manifold.

vacuum gauge shows the vacuum (well duh) of the inlet manifold ie.the more throttle you give the car the higher the vacuum and when de-accelerating it should show a minus pressure

some times usefull on cars with carbs but IMHO useless on a fuel injected car
