Scaling Factors for the E50B2 Power & Energy Meter
If you are using the E50B2 Power & Energy Meter (T-VER-E50B2), you can apply scaling to the Counts channel. The following table lists the names and values you should enter in the Scaling fields. The default settings for the three native E50B2 data outputs are listed as well as all supported scaling values. These scaling factors must match the configuration entered into the device or inaccuracies will result. Documentation on the E50B2 is available at http://www.onsetcomp.com/products/sensors/t-ver-e50b2.

In addition to the three native data outputs (VARh, Wh, and Ah), you can also calculate other types of data outputs. To do this, download the .csv file and follow the instructions in the Microsoft Excel file located here:
http://www.onsetcomp.com/files/manual_pdfs/Derived-Channels.zip
That file uses the following calculations for each additional type of data output:
