3. After connecting correctly, you can measure single phase
power (active power, power factor, apparent power, reactive
power, voltage, current, phase angle, peak value of voltage
and current and frequency).
4. The clamp will perform automatic measurement and
display the active power, and at the bottom of the screen it
will indicate the voltage / current value of the load tested;
Press the MODE key to display the reactive power value on
the LCD screen; Press the WATT key to show the apparent
power and the power factor (cosᴓ); Negative power factor
means that the tested load has a capacitive component.
5. The maximum active power measurement scale is
600kW; If this scale is exceeded, the “OL” symbol will be
displayed on the screen. If the voltage is higher than 600V or
the current is higher than 1000A, the “OL” symbol will be
displayed on the LCD.
1. Set the thumbwheel to position A ~.
2. Press the trigger to open the jaw, and then hug the lead
of the circuit to be measured. The measured current will
be displayed on the LCD screen.
3. Press the MODE key to display the percentage of
harmonics and the ratio of harmonic distortion F and r will
be displayed cyclically.
4. Press the keys to display the value of each
individual harmonic.
If the current through the measured cable is greater than
1000A (RMS), the symbol “OL” will be indicated instead of
the current value.
Notes:
1. You can select the AUTO / FIXED test frequency at 50 /
60Hz. When the input waveform fluctuates, the harmonic
values can be kept stable by selecting the Fixed 50/60 Hz
mode.
2. In the AUTO test frequency mode, the FFT calculation is
only performed when the frequency of the fundamental wave
is between 45 and 65 Hz. If that frequency is outside of that
range, harmonic analysis is not performed.
Single-phase circuit test
1. Clamp the power or charging cable with the clamp. If you
want to measure a specific phase of a three-phase system,
only wrap around the cable corresponding to that phase.
2. Set the thumbwheel to the KW position, select the
corresponding sockets for terminals V1 or V2 and insert the
test leads.
