First, shut off all power to your house.
the meter socket should be 1.8m from finished ground
The electrical power that you use from the utility company has to be metered. This is done with a plug in watt meter. The meter socket is what holds the electrical watt meter. It is this meter that the meter reader reads to give you your monthly billing for the electricity that you used.
Clamp the meter around the energized conductor that is connected to the load to be measured and read the amperage off of the dial face of the meter.
The very first thing you have to do is kill the power to that outlet at the breaker or fuses. If you don't have a meter to check it, plug a radio in, turn it on, then start pulling fuses or tripping breakers until the raido goes off. If the plug has arced and welded itself into the socket, you may be better off replacing the outlet and starting all over again. If you don't know anything about electricity, get someone with the training and equipment to do the job safely.
Carefully! Set your voltage meter to the nearest setting above 120 volt AC. Turn the power on to the socket. Take the lead marked "common" on your meter and touch it to the shell of the socket, that's the metal circular part which the lamp screws into. At the same time take the other "positive" meter lead and touch the tip of it to the brass electrode in the center top of the socket. You should read 110-120 volts. Be REAL careful no to cross your two meter leads or you'll create a dead short and it'll blow up in your face! Wear safety glasses when doing this.
A meter socket adapter is used when solar energy is required to be fed back to the grid from a home owners solar array system. The adapter is on the line side of the service between the utility meter and the utility meter base. A meter base surge protector is a device to stop surging from lightning strikesfrom the grid from entering your home. This device is also connected to the line side of the service between your utility meter and the utility meter base.
You DON'T
With a volt meter check to see if you have power to that socket. Check at the wire not the socket. If you find you have power, either the socket is corroded or broken. Also check the ground connection at that socket.

With the key.
If you charge four 50v capacitors in parallel then remove the 50v battery and hook them up to a volt meter the meter will indicate 50v.
Most municipalities and power companies require that meter bases be installed by licensed electricians.Do not attempt to install the meter base yourself. There are far more realistic ways of saving a few dollars.
