Measuring the Energy Consumed - 2
To use SP8941 to calculate the energy
consumed:
At the start of the measurement period, read the
values of SP8941 001 to 005.
At the end of the measurement period, read the
values of SP8941 001 to 005 again.
Find the amount of time spent in each mode
(subtract the earlier measurement from the later
measurement).
Multiply this by the power consumption spec for
each mode.
Convert the result to kWh (kilowatt hours)
