PA3000 Four-channel, Multi-phase AC/DC Power Analyzer
Efficiency Testing Single Phase Applications
DEMONSTRATION GUIDE
• Waveforms in the PWRVIEW software are constructed using the harmonic data collected
from the power analyzer. The accuracy of the waveform depends on the amount of harmonic
information available. For optimum results, select 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 throug the setup screen. Hovering over any harmonic
bar will display the absolute value and percentage of fundamental for that harmonic.
• The Trend chart can be activated for any measurement parameter by either right clicking on
the desired parameter or by clicking the Trend icon on menu bar. The Trend chart can be reset
by using the Reset button on the menu bar.
Data Logging. Recording data is important for most efficiency measurements where load and
source sweep is required.
