Historical Trend Plot Sub Screens
The historical trend plot screens graph time-stamped feedback data over an extended period of time. Once the
trend plot display data buffer is full the oldest data is overwritten. Historical data can be viewed using the
integrated scroll bars of the trend plot. All trend plot data is maintained between power on/off cycles of the
HarmonicGuard Active filter. See Figure 7.10 for an example of a typical trend graph (trend plot example is
for the HarmonicGuard Active filter power converter heatsink temperature measurement). For data buffer
sample times and size see Figure 7.10.
