Symbol Bar for the Cumulative Frequency Display

Scaling Limit value
Scales the diagram according to the selected limit value level file. Not
available for current cumulative frequency.
Scaling Nominal value
Scales according to the nominal value.
Scaling Class limits
Selects the class limits.
Analysis>Timeplot
Creates a timeplot with selected curves.
Print File list
Prints a list with all harmonics.
Scaling to Limit Values -
The bars of the diagram are scaled to the limits.
For each phase the parameter and the limit are displayed. Each phase has an extra line
with minimum/maximum values, date/time and the 5 % and the 95 % values.
Scaling to Nominal Values
Fundamental is scaled to 100 % of V
harmonics are normally very small in relation to f
the same diagram does not adversely affect the resolution.
Cumulative Frequency – Class Limits
Define the class limits. 95 % and 5 % are the standard class limits. On selecting 95 % for
the lower class limit, the green bars disappear. Then, the presentation is similar to the
graphical overview. If the lower class limit is set to 0 %, the lowest value that ever
occurred, is displayed (there are no other values below this value).
The "Standard" button resets the lower class limit to 5 % and the upper class limit to
95 %. 5 % of all measured values are below the 5 % value.
Timeplot-
Mark important bars in the cumulative frequency diagram. Click the icon
open a Timeplot for the selected parameters.
