Energy Consumption Testing
Energy Consumption Testing
Energy consumption testing on home and office appliances is required for compliance to many
international and regional standards programs such as ENERGY STAR®. Energy consumption
testing involves the integration of power consumed over a long period of time, often days. Use the
dedicated Integration Mode on the PA3000 to make energy consumption testing easier and faster.

TEST SETUP
The following steps describe the process to set up energy consumption measurements on
a home or office appliance using a PA3000. This method can be used for testing energy
consumption of any DUT that plugs into the AC wall socket for power.

1. Connect the AC input on the DUT to the first channel of the PA3000 using a Tektronix
BB1000 Breakout Box as shown in the wiring diagram.
The breakout box taps in to the current signal and measures the voltage across the input
terminals. It makes it easier and safer to connect the input AC signal on the DUT using
the 4 mm safety leads provided with the PA3000.
2. After making all the connections, use one of the two methods to make efficiency measurements.
