Tell us the model number of the meter.

To get a proper (RMS) reading, you will need a 'true RMS' meter.
Otherwise, it reads the peak a nd scales that down by sqrt(2) which

electrical whiz can tell you.


I thought of that, but the most likely cheap-meter equivalent would
be a
square wave, which would read lower.

I suppose that a meter that takes the average of the absolute value
and
then scales _up_ may be off in this manner, however.
