• Dual List
The data of two measurement functions is displayed in its own column. You can
select the following measurement functions: U, I, P, S, Q, λ, φ, φU, φI, Z, Rs, Xs,
Rp, and Xp.
Measurement function 1
Measurement function 2
Numeric data of
each harmonic order
Measurement function display
Data of each harmonic order
Data related to all harmonics
Relative harmonic content of each harmonic
(Uhdf, Ihdf, and Phdf are displayed when the
selected measurement function are U, I, and
P, respectively.)
• Scrolling the Page
The numeric display screen can be switched at the page level. If different items are
displayed on each page, the displayed items can be switched collectively.
• Resetting the Numeric Display
If the number of displayed items is 4, 8, or 16, the displayed order of measurement
functions can be reset to factory default settings.
Equation for Distortion Factor «For procedures, see section 7.6.»
The measurement functions, Uhdf, Ihdf, Phdf, Uthd, Ithd, and Pthd during harmonic
measurement have two defining equations. For the equations, see section 7.9.
