Think I'd want to use something with an RMS converter in it - AVOs are mean-sensing. And I'd observe the waveform on a 'scope to make sure there is nothing funny going on.
How pure a resistance will the Marconi present? Observe the voltage across the test resistor (which obviously gives current), and compare it to the voltage waveform. Moving the resistor if necessary to deal with the common earth of the two 'scope channels, needless to say...
