Safety Specification
AWaming
To avoid possible electric shock or
personal injury, please strictly
observe the following specifications:
® Operate the meter according to the
manual.
Take care when measuring values
exceed 60V DC, 30V AC RMS, or
peak value 42V.
@ Ifthe meter is not normal or
damaged, please do not use it again
® Before using the meter, ensure that
the product is intact.
When the "£3" symbol is displayed
on the meter, replace the battery.
® Do not use the meter in an
environment with explosive gas or
steam or humid environment.
When using the probe, hold your
fingers behind the probe guard,
® When measuring, please connect the
null or ground wire first, then the live
wire; when disconnected, please
disconnect the live wire first, and
then the null or ground wire.

Power on / off
Press and hold the '0" key for about 2
seconds to turn on or off.
Function selection
1) Press “FUNC” key to select function.
2) Press “FUNC” key for about 2
seconds to return to the NCV
measurement.
® Power on is in NCV function mode by
default.
Data hold / Flashlight

2) Press and hold “ " key for about
2 seconds to turn on or off flashlight.
" key to tum on or off

Auto power off
After power on, auto power off will be on
by default and “’y” symbol will be
displayed. Without any key operation in
about 15 minutes, the meter will
automatically shut down to save battery
energy.
Measurement operation
AWaming
® Do not measure the voltage higher
than 600V, otherwise the meter may
be damaged.
® Pay special attention to safety when
measuring high voltage to avoid
electric shock or personal injury.
® Before use, test the known voltage
with the meter to confirm that the
meter is in good condition.
1. NCV measurement
Press the *(1)” key to power on into
NCV measurement mode by default.
2) Gradually close the NCV sensing
area to the measured conductor.
® When the weak electric field signal is
" the
detected, it will display *-
buzzer will sound slowly and the green
4

light on.
® When the strong electric field signal is
detected, it will display “—H"; the
buzzer will sound quickly and the red
light on.
2. Smart (AUTO) measurement
In this mode, DC voltage, AC voltage,
resistance, continuity can be measured,
and the meter can automatically identify
the measurement signal.
1) Press the “ (1) " key to power on.
Then press the “FUNC” key to select
“AUTO" gear, the meter displays
“Auk o’ to enter the smart testing
mode.
2) Insert the red probe into “INPUT"
jack and the black probe into the
“COM " jack.
3) Contact the probe with both ends of
the measured subject or resistance
in parallel, and the meter will
automatically recognize the
measured signal.
4) When measuring the resistance, if
the resistance value is < about 50 @,
the buzzer will sound.
5) Read the results from the display.
5

Note: The minimum measurable
voltage of this mode is about 0.8V.
3. Frequency measurement
1) Press the (1)" key to power on,
then press the “ FUNC " key to select
“Hz" gear.
2) Insert the red probe into “ INPUT *
jack and the black probe into the
“COM " jack.
3) Contact the probe with both ends of
the measured subject .
4) Read the results from the display.
4. Capacitance measurement
1) Press the “(1)” key to power on,
then press the “FUNC” key to select
“IF gear.
2) Insert the red probe into “ INPUT *
jack and the black probe into the
“COM " jack.
3) Contact the probe with both ends of
the measured capacitance .
4) Read the results from the display.
5. Diode measurement
1) Press the “(1)” key to power on,
then press the “ FUNC " key to select
“Bf " gear.

2) Insert the red probe into “ INPUT ”
jack and the black probe into the
“COM " jack.
3) Connect the red probe to the anode
of the diode and the black probe to
the cathode of the diode.
4) Read the forward bias value on the
display screen.
Note: If the electrode of the test wire is
inversely connected with the electrode
of the diode, the display will read OL ,
which can be used to distinguish the
anode and cathode of the diode.
6. Live wire detecting
1) Press “(1)” key to power on, then
press “FUNC " key to select “LIVE”
gear.
2) Insert the red probe into* INPUT
jack and remove the black probe.
3) Use the red probe contact to the
conductor.
@ When the weak electric field signal is
detected, it will display "—L"; the
buzzer will sound slowly and the green
light on.
® When the strong electric field signal is
detected, it will display "—H *; the
7

buzzer will sound quickly and the red
light on.
7. Non-contact phase sequence
detection
1) Press “(1)” key to power on, then
press “ FUNC " key until "PA" symbol
shows on display to enter the phase
sequence detection state.
a) The letter "A" is flashing and stick the
sensing probe to the first phase line
of the socket and waiting for a beep;
b) Display the "PAB" with "B" flashing
and stick the sensing probe to the
second phase line, wait for a beep;
c) Display the "PABC" with "C" flashing
and stick the sensing probe to the
third phase line, wait for a long beep;
d) Atthe end of the test, the display will
show the detection results.
® “P-—-L" showed on the screen indicates
a left-handed phase sequence.
® “P--R" showed on the screen indicates
aright-handed phase sequence.
Note : Please detect the three wires
in 1 minute, if not, the detection
timeout error will occur, the display
wil

shows the PABC symbol and the “P"
flashes at that time. Please return
and test again.
