Please carefully read the instruction manual before
using the tester, and pay special attention to “Warning”
content. Please follow instructions under “Warning”.
1. Please be very careful when test voltage is higher
than AC 30 V, and do keep in mind that your finger
shall not exceed the hand-shielding part of the
test probe.
2. Do not measure voltage which is higher than the
allowed input limit.
3. Before use, please check the meter and test probe;
do not carry out testing in case the test probe is
naked, tester housing is damaged, or there is no
LCD display, etc..
4. It meets requirements of safety standards only when
the meter is used together with the supplied test
probes. In case the test probe is damaged and

1.According to the connection mode as above Table ,
switch the function switching knob to V~, select
corresponding sockets from V1, V2, or V3 terminal,
and insert the test wire.
2.Connect the two test probes V1, V2 to the power
source or load to be tested. The meter will automatically
test and display the result, and the present harmonics
percentage will be shown on the following line.
3.Under voltage test mode, press SET button to show
”Auto V” and “Auto A” on LCD, and press to select a
proper voltage range, and then press SET to return.
4.Press MODE button to show harmonics percentage
on LCD, and the total harmonic distortion ratio F and R

1.Switch the function knob to A~ position;
2.Pull the trigger to open the clamp, and then clip a
wire which is to be tested; the measured current
value will be automatically shown on LCD
3.Press MODE button to show harmonics percentage
on LCD, and the total harmonic distortion ratio F and
r will be cyclically displayed.
4.Press ▲/▼ button to display value of each
measurement of the harmonic.
If current of the wire being tested is greater than
1000 A (RMS), ”OL” symbol will be displayed instead
of current value.
Note:
1.You can select 50/60-Hz FIXED/AUTO frequency
test (AUTO). When input waveform fluctuates,
displayed harmonic values can be kept stable if
50/60-Hz FIXED mode is selected.
2. Under AUTO frequency test mode, FFT calculation
is performed only when base-wave frequency is
between 45 and 65 Hz; harmonic analysis is not
performed when base-wave frequency exceeds
this range.
Test of single-phase circuit
1.Clip the clamp on the test wire of the power supply
or load. If the user needs to measure a certain phase
of the 3-phase circuit, then the clamp should clip on
the wire of the same phase.
2.switch the function switching knob to KW position,
select corresponding input sockets from V1 or V2
terminal and insert the test wire.
3. After it is correctly connected, you can measure single-
phase power (active power, power factor, apparent
power, passive power, voltage, current, phase angle,
peak value of voltage and current, and frequency):
4. The meter will carry out automatic measurement and
display active power, and voltage/current value of the
load being tested will be displayed on the bottom line
of LCD; press down MODE button, Var value of
passive power will be displayed on LCD; press WATT
button to display apparent power and power factor
(cos Φ); negative power factor signifies that the load
being tested is a load with capacitor characteristics.
5. The maximum measurement range of active power kW
is 600 kW; if this range is exceeded, “OL” symbol will
be displayed beyond this range. If voltage being
tested is greater than 600 V, or current being tested
greater than 1000 A, “OL” symbol will be displayed
on LCD.
