Copying from my post on e-catworld:
Can anyone on this forum comment on the True RMS meter that was used?
The link Frank supplied seems to suggest that one of its applications is
to find unexpected high currents.
So a typical scenario may be this: you have fuses that repeatedly blow
and your normal ampmeter does not find any justification for that fact.
This True RMS meter would show you the real --- higher --- current.
Now, we know such ampmeters and multimeters have digital displays that
only update once every second, or half second at most. Somewhere in that
meter, there must be an algorithm that determines what value to display
next. Usually that would be an average value of the last period. But
knowing that this device is often used to find unexpected high currents,
could it be that it displays the max value? (or the max average of all
the intervals of a typical duration that would be enough for a fuse to
blow)?
Depending on the duty cycle of the (presumably PWM driven) resistive
heater, this may give too high values at swithing on. This is why he now
suggests using a variable AC transformer, to stop using PWM.
Keep in mind that I am just a software engineer, so take it easy on me.
Just trying to hold on to my hope just a little bit longer.

output when Lewan is out of the room and he is not being watched (far
more steam as Lewan replaces the tube than when he first pulled it out).
I no longer think it was ignorance on Rossi's part that lead to such
consistently bad calorimetry and ambiguous results, he was trying to
create uncertainty and wiggle room for himself to be able to
exaggerate his results. It is notable that the few independent groups
of testers that really had proper access to check results (NASA linked
group, Defkalion now Swedes) have all had tests that were either
didn't work or under-delivered on promises, would love to hear from
insiders who were there. And we know that Rossi has lied on many
other occasions too (eg shipment of 1MW unit).
Totally massively untrustworthy.

To what faked results are you referring exactly?
