Description. Type in useful information about the measurement session for the report. Include
information about the measurement location, who performed the installation, and the type of
equipment being monitored.
Duration, Start Time. 10 minutes, 1 hour, 1 day, 1 week, and 30 days are the preset durations
available for logging sessions.
There are also special settings:
No End: a session that never ends, when the memory is full, the memory is overwritten.
The length of the session depends on the selected average period and the detail of the
harmonics logging.
Maximum: a session that fills the memory and then stops.
Custom: provides the flexibility to select the length of the session in terms of a chosen
number of days or hours.
For each of the duration selections (except No End) select a Start Time. This can be
immediately when the session starts or a future date (day, month, and year), hours, and
minutes.
After setting the Start Time, select Done. Select Done once more to exit the Duration, Start
Time screen.
An overview of the Session Settings shows on the display. The next step is a final check to
ensure the wiring to the Analyzer is correctly connected. When everything is correct, start the
session. The Analyzer now shows the measurements in process. For a future start time, a
count down timer shows when the first readings will be available.
Trend Interval. The trend interval selection provides for the resolution of the trend plots
recorded by the Analyzer. This selection impacts the amount of memory used like duration.
Select Done to exit Trend Interval.
Harmonics. The Harmonics selection allows the addition of interharmonics to the recording.
For IEEE 519 purposes, 3-second harmonics can be selected. When evaluating the impacts of
higher-order harmonics introduced into the power system from energy conversion systems
like inverters, check the Supra-harmonics box to measure harmonics up to 30 kHz. Select
Done when finished to return to the main Session Settings screen.
