Model 9624 PQA HiVIEW and Model 9624-10 PQA HiVIEW Pro show the harmonic time plot
graph by connecting the maximum and minimum values in each interval with a horizontal line.
Therefore, a rapid change is reflected in the time plot graph.
However, the judgment of inflow and outflow is not easy to make using that time plot graph, so we
recommend converting the data to CSV format and creating a graph with "AvePhasesum" of the
relevant harmonics order only (without using "MaxPhasesum" and "MinPhasesum"), to determine
the inflow and outflow.
