Displaying Data According to % of Limit on the Y-Axis
Click with the right mouse button on any area of the graph. This puts up the Edit Graph Attributes dialog
box, in which you can reformat the y axis to display the data in percent of the specification limits rather
than in absolute values. In this case the display appears as follows:
The red line that appears across the display indicates the specification’s limits. All values above the red
line are outside the specification’s limits.
Note By definition, there are no limits for Harmonic #1 (the fundamental). No data will appear
in the graph when viewing harmonic #1 according to % of limit on the Y-axis.
Search Parameters
When the display is set to Fixed, you can perform search functions on specific test data. Search options
let you:
ñ Search for specific items such as:
single failures
2.5 minute failures (only applies to fluctuating harmonics)
all failures (only applies to fluctuating harmonics)
harmonic magnitudes > than the specified value (specify AMPS or % of Spec. in the Edit
Graphs dialog box)
