With this data, and the power consumption values from the specifications, we can estimate the amount
of energy that is used by the machine.
This should only be used as a reference value, because the power consumption specifications are
measured in a controlled environment with a constant power supply.
To get an exact measurement at the customers site, a watt meter must be used to measure the actual
energy consumed.
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)
Here is an example calculation.
