Charging description
The device has a built-in lithium battery. If the battery level
is low, a low battery symbol will appear, the battery needs
to be charged. Regarding the specification of the charging
adapter, USB 5 V 600 mA, at least ~2 A is required for proper
charging. Connect the Type-C charging cable to the device
and then to the charging adapter. The red indicator LED
lights up during charging, a green indicator light indicates
that the battery is fully charged.
Remark: For safety, do not use the meter while charging, it has
a protection setting, the meter will automatically turn off and
cannot be used when the charging cable is inserted to charge.
HOLD B/L
Press this button briefly to keep the measurement result on
the screen. If the status is active, the
the screen. To turn the backlight on/off, press and hold the
button for ~2 seconds. (Backlight turns off automatically
after 15 seconds)
Warning: To avoid possible electric shock, fire or
personal injury, do not use data retention function to
measure unknown voltage. When the HOLD function
is opened, the LCD will keep the original data when
measuring a different voltage.
NCV /
Briefly press the button to select NCV mode. Long press the
button (~2 s) to activate the flashlight on the back.
FUNCTION BUTTON
Briefly press this button to switch between individual
measurement functions. (Resistance measurement, diode
test, capacitance measurement, DC V, AC V, frequency
measurement, automatic identification mode „AUTO")

• First of all, please check if the battery charge is sufficient.
If the charge level is not enough, the
appear on the LCD screen and you need to charge the
built-in battery. Pay attention to the
connector of the test leads. This warns that the voltage
and current must not exceed the indicated value.
• „AUTO" mode can measure resistance (R), continuity,
DC V, AC V, DC A, AC A.
• „FUNC" manual mode can measure resistance (R), diode
(D), capacitance (C), DC V, AC V, frequency (Freq) and can
also do automatic identification (AUTO).

symbol will
mark next to the
DCV and ACV measurement
• Switch to automatic / manual mode, connect the test
leads to the tested circuit. The polarity of the red wire
and the measured voltage are shown on the display.
• Insert the black wire into the „COM" socket, the red wire
into
the socket.
• You can read the measurement result on the display.
The main display shows the tested voltage value, the
secondary display shows the normal temperature (DC V
measurement) and the accompanying frequency (AC V
measurement), the measured AC V must be ≥ 50 V for the
accompanying frequency.
Useful information:
• The LCD shows „OL" if the measured value is outside the
measurement range.
• When measuring high voltage (>220 V), personal
protective equipment must be worn (for example:
Approved rubber gloves, face mask and flame-resistant
clothing, etc...) to avoid injuries from electric shock and
arcing.
• If the input AC V / DC V voltage exceeds 24 V, the screen
will turn red, warning of high voltage.
DCA and ACA measurement
1. You can also use it in automatic mode
2. Plug the black test lead into the „COM" socket, the red
one into the „mA/A" socket, then connect the test leads
to the power supply voltage or circuit under test.
3. Read the result on the LCD display.
Useful information:
• Before connecting the test leads to the power supply
or the circuit, first turn off the circuit power, and then
check that the input terminal and function range are set
correctly.
• The maximum measurement current is 600 mA, alarm is
set off when the measurement range is exceeded this.
• Overload or malfunction will trip the fuse and may
damage the meter.
• Read the result on the LCD display. The main display
shows the tested current value, the secondary display
shows the temperature (DCV measurement) and the
auxiliary frequency (in the case of ACV measurement)
Resistance measurement
• You can turn on the resistance test function in automatic /
manual mode.
• Then connect the test leads to the resistance you want
to test.
• Plug the black test lead into the „COM" socket and the
red one into the
• Read the result on the LCD display.
Useful information:
• The LCD will show „OL" when the resistance exceeds the
range. If the measurement resistance exceeds 1 MΩ, the
meter may take a few seconds to stabilize. This is normal
when testing high resistance.
