The meter and the software are easy to use.  It measures all electrical characteristics of an appliance needed for a common load analysis.  It will display data as you use it and also interface to your PC when you have finished measuring an appliance.  The graphs are easily configurable and can be used to teach principles of load analysis.  The payback calculator is a useful tool for anyone wanting to see the economic payback of upgrading to a more energy efficient appliance.

We found the SunFrost RF-12 refrigerator freezer was using 18 kilowatts a month, but after defrosting only used 14 kilowatts a month.

We have two Watts Up? meter and are willing to loan them out to people who and to measure their appliances (and return the WattsUp?, of course).  You can also buy them from
