Reactive Powers
Total Reactive Powers
VAr and HAR LEDs on the display represent that displayed values indicate
harmonic values of the reactive powers. By pressing the SET button
repeatedly, odd-numbered harmonic values up to 19th harmonic can be
observed.
VA and HAR LEDs on the display indicate that displayed values are
harmonic values of the apparent powers. By pressing SET button
repeatedly, odd-numbered harmonic values up to 19th harmonic can be
observed.
In the measurement mode, reactive power values are displayed by using
UP/DOWN buttons when VAr LED lights. When reactive power values
are displayed, if SET button is pressed (HAR LED lights), odd-numbered
harmonic values up to 19th harmonic can be observed.
When active power values are displayed, if the DOWN button is pressed,
inductive reactive and capacitive reactive power values are observed.
As seen in the example below, total reactive inductive power value is
displayed on the first display and total reactive capacitive power value is
displayed on the third display.
Note : The dot at the most right digit of the third display indicates that
the displayed value is capacitive reactive power.

Apparent Powers
In the measurement mode, apparent power values are displayed by using
the UP/DOWN buttons when VA LED lights. When apparent power
values are displayed, if the SET button is pressed (HAR led lights), odd-
numbered harmonic values up to 19th harmonic can be observed.
