When measuring expansion tank air pressure the boiler pressure must be at zero - which really means you will need to shut down the heating system, cool it, and drain all pressure off of the system before measuring expansion tank pressure, or you need to measure the expansion tank's air pre-charge pressure before the tank is installed.

Regarding this, what does the expansion tank on a boiler do? These expansion tanks are used to provide a cushion for the expansion of water when it is heated. Without this cushion of air, the pressure in the boiler system would exceed the setting on the pressure relief valve. Finally, this will cause the pressure relief valve to open and discharge water to relieve the pressure.

You are correct. The expansion tank is usually about half full of water and half full of air--by volume. One tank full of air at atmospheric pressure will be about half its volume when pressurized. When in doubt, drain it. First, shut the valve between the tank and the boiler, or the rest of the system. Then open the drain valve on the tank.
