I think the confusion has come about as I certainly took it Mike was trying to measure the load current from the supply which to all intents and purposes is a high frequency square wave with varying MS ratio.
There should be no issues measuring the 50Hz AC input current with a moving iron meter even with a SMPS type of supply. I've done it many times and so long as inefficiency is taken into account it's fairly accurate.
