12 Bar Graph Display (Option)
Bar Graph Display (OTHERS (Bar))
On models with the harmonic measurement option or the simultaneous dual harmonic measurement option,
you can display harmonics using bar graphs. The harmonic orders are lined up on the horizontal axis, and the
vertical axis represents the amplitude of each harmonic.
You can configure three different bar graphs.
Bar Graph Display Example
The bar graph number, measurement function, element, and upper limit of the
displayed bar graph
The bar graph number, measurement function,
element, and lower limit of the displayed bar graph
Harmonic order range of the displayed bar graph
“log Scale” only appears when logarithmic coordinates are used.
• When logarithmic coordinates are used (Log Scale), if a value is negative, its absolute value is displayed
with a red bar graph.
• If the analysis window width (number of cycles of the fundame
ntal signal) that is determined by the
fundamental frequency is shorter than the data update interval, bar graphs are not displayed. Set a longer
data update interval. For details, see “Notes about the Numeric Data Display.”
• The bar graphs of harmonic orders that exceed the maximum measurable order are not displayed. For
information about the maximum measurable harmonic order, see “Maximum Harmonic Order to Be
Measured (Max Order).”
Display Format (FORM)
Number of Bar Graph Display Windows (Format)
You can choose the number of windows from one of the following options:
• Single: No windows. The data of bar graph (Item No.) 1 is displayed.
• Dual: Two windows. The data of bar graphs (Item No.) 1 and 2 is displayed.
• Triad: Three windows. The data of bar graphs (Item No.) 1 to 3 is displayed.
