It was measured by thermal effects...

For example, the Balantine 323 has a nice big dial. You would have
to measure the voltage drop across a known value shunt resistor in
series with the load, and calculate the power from voltage and
current.
Ummm... He was talking about RMS, which implies voltage or current. There's no such thing as RMS power.
