•When window 4 displays"or01"~"or50",
Window 1: the voltage measured value of the current harmonic times，the unit is V.
Window 2: the current measured value of the current harmonic times，the unit is A.
Window 3: the total RMS power (operation value) of 1~50 times，the unit is W.
•When no voltage signal is input or voltage frequency is over the range,
Window 1, 2, 3 displays"-----".
•When no current signal is input,
Window 2 displays"-----".
3.3.5 Harmonic Distortion Factor
Press【THD/%】key to enter harmonic distortion factor display interface.
Notes: If press【THD/%】 key multiple times, the system switches between the measured value of harmonic
display interface and the harmonic distortion display interface, please select the appropriate interface. The
following figure is harmonic distortion factor display interface.
Window 4 displays "tHD"or "or01"~"or50". "tHD"represents the total harmonic distortion; "or01"~"or50"
represents the currently selected harmonic times. The display item of window 4 can switch by 【 ▲】 or 【 ▼】 .【▲】
or【▼】key supports continuous press function, long press the two keys to quickly switch the display item.
•When window 4 displays"tHD",
Window 1: voltage total harmonic distortion factor，the unit is %.
Window 2: current total harmonic distortion factor，the unit is %.
Window 3: the total RMS power (operation value) of 1~50 times，the unit is W.
•When window 4 displays"or01"~"or50",
Window 1: voltage distortion factor of the current harmonic times，the unit is %.
