Question on Coleman 100W Solar Panel "open circuit" voltage

So just one last question. I just want to confirm that the " Isc (short circuit) " test you put an AMP meter between the positive and negative leads of the panel while it's disconnected from the controller. I wanted to double check because this really is short circuiting the solar panel and i don't want to do a smoke test on it :-)

Edit: while it's in full sun
