After this warm-up period, the AC input power is monitored for a period of 5 minutes to
assess the stability of the UUT. If the power level does not drift by more than 5% from the
maximum value 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 overtime for both AC
input and DC output.

Some wattmeter models allow the integration of the measured input power in a time range
and then measure the energy absorbed by the UUT during the integration time. The
average input power is calculated dividing by the integration time itself.
