measurement error.
• Do not use the instrument around explosive gas, steam, or in an wet environment.
• When using the probe, please put your fingers behind the finger protector of the
probe.
• When measuring, please connect the zero (neutral) line/ ground line first, then
connect the live wire; when measuring is done, please disconnect the live wire first,
then disconnect the zero (neutral) line / ground line.
• Before opening the outer cabinet or the battery cover, please remove the probes
from the device. Do not use the device, when it is taken apart or the battery cover
is open.
• The safety standards are only met when the instrument is used together with the
supplied probes. If the probes are damaged and need to be replaced, only use
probes with the same model number and the same electrical specifications for

Smart Measurement Mode
The device features a smart measurement mode, through which the device can
automatically choose and determine which measurement function use, without the
operator choosing it manually. The smart measurement mode is enabled by default
when turning on the device. The mode is applicable for AC/DC voltage, resistance, and
continuity measurement. Note: Minimum measurable voltage: 0.5V AC; 0,8V DC
1. Press the button to turn on the device. The display will show , indicating
that the smart measurement mode is enabled
2. Insert the red probe into the input socket and the black probe into the
"COM" input socket. Let the probe’s tips touch one another, to check whether they
are correctly connected. The indicator light should turn green and the buzzer sound.
3. Connect the probes’ tips (red probe is the positive pole, black probe is the negative
pole) in parallel to voltage source / resistor and the device will automatically
recognize the signal and choose the correct measurement function.
4. When Measuring AC voltage, the frequency will be displayed at the same time.
5. When the measured resistance is less than 50Ω, the buzzer will sound and the
indicator light will turn green. The device switches to continuity testing.
6. Results will be shown on the screen of the device.

15
WARNING:
• Do not measure voltage above 1000V DC or 750V AC; otherwise the
instrument might get damaged.
• If the display shows “OL”, disconnect the probes’ tips from the measuring
circuit immediately (Overload)
• Never connect voltage if probes are in current measurement sockets. This
could result in electric shock for the user and damage the device.
• Pay special attention to safety when measuring high voltage to avoid electric
shock or personal injury.
• Always test known voltage before using the device, in order to ensure that
the device functions properly.
• Do not touch the bare tips of the probes; when measuring is finished, always
remove the probes from the measuring object and the device.
When measuring resistance / testing for continuity on the line, disconnect the
power supply, ensure there is no source of voltage, and discharge all capacitors.
Otherwise, the instrument might get damaged and might be in danger of an
electric shock. When measuring is finished, always remove the probes from the
measuring object and the device.

3. Connect the probes’ tips (red probe is the positive pole, black
probe is the negative pole) to the measuring object, measure
the resistance.
4. The measurement result is displayed on the screen.
5. When measuring large resistors (>1MW), it can take a few
seconds for the measurement result to be stabilized. If the
screen shows “OL”, the measurement range has been
exceeded or the measuring circuit is defective.

19
WARNING:
When measuring resistance on the line, disconnect the power supply, ensure
there is no source of voltage, and discharge all capacitors. Otherwise, the
instrument might get damaged and might be in danger of an electric shock.
When measuring is finished, always remove the probes from the measuring
object and the device.

Continuity Test
1. Press the button to turn on the device. Insert the red probe
into the input socket and the black probe into the
“COM” input socket. Let the probe’s tips touch one another, to
check whether they are correctly connected. The indicator light
should turn green and the buzzer sound.
2. Press the “AUTO/FUNC” button and choose the function.
3. Connect the probes’ tips to the measuring object.
4. The buzzer will signal if continuity is present (resistance is less
than 50 W.) and the LED-indicator of the device will turn green.
In addition the resistance will be shown on the screen. If the
screen shows “OL”, the measurement range has been
exceeded or the measuring circuit is defective.
