Chapter 3 Basic operation
3.1 Function switch
Function Description
SETUP
Settings
Changes and confirms the settings for wiring, VT/ CT ratio,
buzzer on/ off, backlight on/ off, nominal frequency 50/ 60Hz. To
restore all the settings to the default conditions, perform system
reset.
Phase
detection
Tests and shows the phase rotation sequence, and missing
phase if there is any.
Harmonics
Shows voltage/ current (of the 1st fundamental waveform up to
30th harmonics) RMS value, content rate, and distortion factor
[THD-R/THD-F].
W
Power
Shows: active/ reactive/ apparent power, power factor,
voltage-current phase differences, and voltage/ current (RMS)
value.
～
V
AC voltage Shows AC voltage RMS value, peak value, and frequency.
～
A
AC current Shows AC current RMS value, peak value, and frequency.

Data hold button
Hold down the Data hold button until the LCD shows “ ”
symbol: then the currently displayed value is held. While this
function is activated, readings don’t change even the input
value varies. To exit from the hold mode, press the data hold
button again or switch the measurement functions: the “ ”
symbol disappears.
Backlight button
[ ◄ ] A long press turns on/ off the backlight.
SETUP
Item switching
button [ ◄► ] Toggles displayed items and changes the setting values.
Mode button Selects setting items and confirms the entered values.
