The image in the upper section of the Harmonic Analysis window is a single waveform snapshot. The
first image is by default channel 1, but you can select different channels and update the image, copy
the image to the clipboard for pasting into other programs, or print the image.
You can also record the harmonic values to your PC and then view a log of the harmonics in a
spreadsheet. When you click Record to PC the Harmonic Logging Parameters dialog box displays.
1) Select the Waveform Summary Data check box to create a “single column” of data in a spreadsheet
stored on the PC. The data is the average harmonic content for each harmonic of the first 31
harmonics over the period of time the harmonic data is collected.
Selecting Raw Harmonic Data creates a spreadsheet with the information above and a “row” of
the 31 harmonics for each update of the logger. Since the logger updates faster than one time
per second, selecting this option will create a LOT of data quickly!
2) Click OK and the recording begins.
The Record to PC button now reads Stop Recording on the Harmonics Analysis screen. Click that
button to stop recording harmonic values to the PC.
3) Click View PC Log to open a file of recorded harmonic values in a spreadsheet on your computer.
Realtime Peak Demand
When a logger is connected with Power 5 and/or Power 6 Channels on, select Logger > Display Real-
Time Values > Realtime Peak Demand to request a report showing peak demand and totalizer
values directly from the logger instead of from a data file.
