Figure 42: Efficiency Trend Chart
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
harmo
nics are selected, waveform feature will display a blank screen.
The Harmonic bar chart can be enabled for all voltage, current, and watts
meas
urements. 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 be activated for any measurement parameter by either
right clicking on the desired paramete r or by clicking the Trend icon on menu
bar. The Trend chart can be reset by using the Reset button on the menu bar.
