6.5.4 Recordings Configuration
The Recording window shows the dialog box used to configure the parameters for
a recording session.
Figure 6-9
Four different configurations are available. More configurations can be saved by
pressing
“Save to File”
and recalled later by pressing
“Load From File”
.
1. Check the configuration you wish to set up: 1, 2, 3 or 4.
2. Check all the “Data to Record” parameters you wish to record by clicking on
each one.
3. Configure the harmonic values to be recorded, if desired.
It is also possible to record up to 2 of 4 types of harmonic data, voltage (Vh),
current (Ah), phase to phase voltage (Uh), and power (VAh).
For each selected harmonic data type, you can choose a range of harmonics
to record from the 1st to 50th. You can further limit that range to only include
odd numbers by checking the box for “Odd Harmonics Only”.
The PowerPad
®
loses its scheduled recording if it is powered off before the
recording begins. If it is powered off during the recording, a partial record-
ing will usually still exist but with the first letter of its name changed to “@”.
The start and end times requested for the recording might be adjusted by
the PowerPad
®
to be in even multiples of the averaging period. For instance,
if an integration period of 10 minutes was requested, and the start time
was 9:03, the recording might not actually begin until 9:10.
