That would not be a ground. If you want to test for a true
ground source you will need a multimeter. To get an earth
ground you would need to drive a ground rod about 3 feet into
the ground. Since you are in an apartment the center screw on
the outlet is your only option. BTW, that metal rail you are
using now is useless. You still have to check that the center
screw is grounded,sometimes they are not.
