Off topic-testing 3 phase power

Hey All,

I find myself needing to verify that an outlet is supplying 16 amps at 400 volts Alternating Current at 50 Hz. I have verified the voltage with a multimeter but feel I should be more thorough.

I’m trying to purchase an appropriate european socket tester which is much cheaper if not as versatile as Fluke 109-104.

 I also have a Tektronix 2355 which I think I could measure each line on it’s own channel to measure the voltage and the phase. Is there a safe way to measure current with this oscilloscope?
