Clamp onto T(L3) phase
While the LCD is showing the 3rd time measurement
screen, move the current sensor and red test lead
to T(L3) as shown to the right.
Press the item switching button [
►
] after making
connection, the LCD shows active power of T(L3)
phase. Pressing mode button switches the
indication to RMS voltage/ current values of T(L3)
phase.

6.4 Harmonics measurement
Set the function switch to
”
”.
The nominal frequency is displayed as
right figure at harmonics function. Nominal
frequency can be set to 50Hz or 60Hz on
SET UP function. (See P.19 “Frequency of
nominal voltage”.)
The LCD screen will be as the right figure
shows during Bluetooth communication:
no measured values are displayed. The
measured values can be checked by using
the application on your smartphone or
tablet device, or by disconnecting the Bluetooth.
Current harmonics distortion factor, content rate, RMS value
Current measurement ranges switches automaticay deoending on the measured value.
When the unit shown in the LCD is “V”, it means the
screen is “voltage harmonics measurement screen”. Hold
down (long press) the Item switching button [►] to switch
the unit to “A”.
[ Item switching button [
◄►

A short press toggles the displayed measured values:
RMS/ Harmonics distortion factor THD-F, RMS/ Harmonics distortion factor THD-R,
1st fundamental wave RMS/ content rate to 30th harmonics RMS/ content rate
RMS/ Harmonics distortion factor THD-F
RMS/ Harmonics distortion factor THD-R
30th harmonics RMS/ content rate to
1st fundamental wave RMS/ content rate
~
The upper row shows the order of the harmonics (1h to 30h) and RMS of each harmonics:
these two switches every second.
