Well, with the inductive loads on which I've tried it (e.g. central
heating pump) the displayed numbers stack up - in that displayed
watts = displayed volts x displayed amps x displayed power factor.

Volts and amps are easy to measure fairly accurately the phase angle
not so easy but once you have that the rest is just maths.

Nice to know that the device does produce reasonable answers, thanks
for running the tests. Pity you're not on commission...
