It is a bit safer to disconnect the NEUTRAL wire and put the meter in series between the wire and the neutral terminal on the element. Doing it this way will give the same reading but the loose wire is neutral and the more dangerous place where the other meter lead has to go is fixed on the heater assembly and so not moving around.
NOTE the neutral terminal will have live voltage on it via the element when it is not connect to the neutral wire directly or via the meter
