Only by pulling the outgoing meter tails
Of course, you need to do this "live"; I would employ a local sparks to do this for you.
Mark the tails with tape and photograph, so you guarantee getting them back correctly.
It's technically illegal to tamper with the meter connections (hence getting a local to do it), but they are rarely sealed and nobody actually cares.
Or, as noted above, call PEA, but still mark and photograph the tails, even PEA can (and do) get it wrong.
