The Watts Up? Pro, Pro ES, and .Net, support downloading the data from the meter's internal flash.
When the software starts, you get a data logging wizard that will guide you through polling the data on the meter.
After a couple of clicks, your data is ready with eighteen different columns, one for each metric. You can configure the meter to record any combination of the available metrics.
If you prefer, the software will align your data in a graph. You can switch the chart to 3D mode as well. In 3D mode, you can control the depth, and rotation, via sliders at the bottom left.
