3.3 Displaying Apparent Power, Reactive Power,
and Corrected Power
This instrument calculates, based on equations that are defined, apparent power (S), reactive power
(Q), and corrected power (Pc) from the measurements of the voltage and current applied to the input
elements or wiring units and shows calculated results on the screen.
► “Equation for Apparent Power (S Formula)” in the features guide
► “Apparent Power and Reactive Power Computation Types (S,Q Formula)” in the features guide
► “Equation for Corrected Power (Pc Formula)” in the features guide
To determine apparent power (S), reactive power (Q), and corrected power (Pc) values, you need to
set equations.
Using an example, this section explains how to display computation results numerically.
In addition, this section explains operating procedures using the following setup methods.
• Procedure Using the Setup Menu (see chapter 1)
• Procedure Using the Menu Icons (see page iii)

Switches the displayed page (Page Up/Page Down)
Switches to the measurement display of another input
element.
Tap ▲ or ▼ to change the displayed page in
order from the current number. Tap the number directly
to change to the number display page.
If you hold your finger down on the 4-, 8-,
16-value, matrix or harmonics display for at least
1 second, you can perform the operations
described in “Switching the Displayed Items
(Items),” provided later.
Note
Apparent power, reactive power, and corrected power values can be shown graphically.
• The trend display(see section 6.3) shows apparent power, reactive power, and corrected power values
graphically.
