DEMONSTRATION GUIDE
Waveform, Harmonics, and Trend Chart. In the measurement grid, you can view waveforms,
harmonics, and trend charts by clicking the respective icons on the menu bar.
• Waveforms in the PWRVIEW software are constructed using the harmonic data collected from
the PA3000. The accuracy of the waveform depends on the harmonic information available.
For optimum results, select the maximum number of harmonics to display in the setup area.
Selecting 100 harmonics for the PA3000 gives the best results. If no harmonics are selected,
waveform feature will display a blank screen.
• The Harmonic bar chart can be enabled for all voltage, current, and watts measurements. Up
to 100 harmonics can be selected through the setup screen. Hovering over any harmonic bar
will display the absolute value and percentage of fundamental for that harmonic.
• The Trend chart can activated for any measurement parameter by either right-clicking the
desired parameter or by clicking the Trend icon on menu bar. The Trend chart can be reset by
clicking the Reset button on the menu bar.
Custom Limits. Custom limits can also be set with any of the measurement parameters. Custom
limits help set limits based on various standards or test specifications.
• To set custom limits, either right-click the desired measurement parameter or click the Limits
Setup icon on the menu bar. Stop the measurement update to set up custom limits.
• Custom limits will appear as a separate tab on the measurement grid. The result column will
display red fonts if the limits are failing. Hovering over the results will display the limit function,
limit value, and relative value.
