    Yes. If you get them the wrong way round it will just measure -ve. make sure the meter is set to DC and AC for the mains side. Be careful .

    Edit: I had not refreshed by browser so didn't see Jazz post.. Just to make sure that there is not a short on the output make a good pic. and remove all the wires on the DC side and check again.
