8.4 Displaying Harmonic Measurement Data
Explanation
For the meanings of the measurement function symbols, see section 1.2, “Measurement
Modes and Measurement/Computation Periods,” 1.7 “Numerical Computation,” and
appendix 2 “Symbols and Determination of Measurement Functions.” For details
regarding the wiring methods, A and B, see section 5.2, “Selecting the Wiring Method.”
Example
The voltage of the 20th order harmonic of element 2
U2(20)
20th order
Element 2

harmonic of the power measurement modules (element) that are
wired using wiring method B

Selecting the display format
Select the display format of the numerical data from the following choices. No data [--
-----] are displayed in places where the measurement function is not selected or there
are no numerical data.
• Numeric
Only numerical data are displayed.
• Wave
The numerical data and waveform are displayed separately in the top and bottom
windows. For the procedures related to setting the waveform display, see sections
9.1 to 9.8.
• Bar
The numerical data and bar graph are displayed separately in the top and bottom
windows. The bar graph is useful when making harmonic measurements. For the
procedures related to setting the bar graph display, see section 9.10, “Displaying the
Bar Graph of Harmonic Data.”
• X-Y
*
The numerical data and X-Y waveform are displayed separately in the top and bottom
windows. For the procedures related to setting the X-Y waveform display, see section
9.11, “Displaying the X-Y Waveform.”
*
X-Y waveform display is applicable to products (PZ4000) with firmware version 2.01 or later.
Selecting the number of displayed items or list display
Select the number of items that are to be displayed concurrently or list displays from
the following choices.
• 8
• When the display format is [Numeric], eight items of numerical data are
displayed in one column.
• When the display format is other than [Numeric], four items are displayed.
• 16
• When the display format is [Numeric], 16 items of numerical data are displayed
in two columns.
• When the display format is other than [Numeric], eight items are displayed.
