The Time-series display presents the following data for the selected harmonic:
ñ the total time of the selected span along the X axis.
ñ the magnitude of the specified harmonic along the Y axis in absolute values. You can edit the
graph to display the data according to % of limit on the Y-axis as described in the following
section.
If the bar is green, it means that the present value is within the regulation’s specification. If the
bar is red, it means that the present value is outside the regulation’s specification.
ñ You can zoom in on any area of the graph by drawing a zoom area with the left mouse button
and then double-clicking inside the area. The zoom has a minimum range of one data point per
bar, and a maximum range of 10 minutes within the total display window.
The red line that appears across the display indicates the specification’s limits. All values above the line
are outside the specification’s limits.
The blue line indicates the maximum measured value within the range selected by the zoom control.
Note By definition, there are no limits for Harmonic #1 (the fundamental). All bars will be
green, and the red line indicating the specification limits will not appear.
