observed, the UUT can be considered stable and the measurements can be recorded at the

end of the 5-minute period. If AC input power is not stable over a 5-minute period, the

average power or accumulated energy is measured over time for both AC input and DC

output.

Some wattmeter models allow the measured input power to be integrated in a time range

and then the energy absorbed by the UUT to be measured during the integration time. The

average input power is calculated by dividing it by the integration time itself.
