category, voltage, or current rating.
• Do not exceed the max. input values as specified in this manual.
• Never change the measurement function during a measuring operation on an object
or circuit. Always disconnect the measuring object/circuit first.
• Opening, repairing, or maintenance should only be executed by trained/qualified
professionals.

9
• Never look directly into the LED flashlight of the device. Non-compliance bears the
risk of permanently damaging your eyesight.
• Please comply with the local and national safety code. Wear personal protection
equipment to prevent any injury through being exposed to electrical shock or
electrical arc caused by an exposed hazardous live conductor.
• When low battery is indicated, please replace the battery in time to prevent of any
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
replacement.

AC/DC Voltage “V / mV" Measurement
1. Turn the rotary switch to the measurement function “ ” or
“” and select either the AC or the DC voltage function with
the "FUNC." button.
2. When dealing with an unknown voltage range, always start
with the higher measurement range “ ”, then switch to the
lower range “ ”, if applicable.
3. Insert the red probe in the “ ” socket and insert the black
probe in the “COM” socket.
4. Connect the probes’ tips (red probe is the positive pole, black
probe is the negative pole) in parallel to the measuring circuit,
measure the voltage.

• If the display shows “OL”, disconnect the probes’ tips from the measuring
circuit immediately (current exceeds measurement range).
• Always test known current before using the device, to ensure that device
functions properly
• When measuring large current (>5A), continuous measurement should not
exceed 10 seconds. After that, disconnect the device from the measuring
circuit and do not use the multimeter for 10 minutes.
• When measuring is finished, always remove the probes from the measuring
object and the device.
Caution:
To avoid damaging the instrument or equipment, check the fuses before
measuring and ensure that the measured current does not exceed the rated
maximum current. If the fuses are released during measurement, stop the
operation immediately. Always use the correct input sockets.

Resistance Measurement
1. Turn the rotary switch to the measurement function “ ” and
select the resistance measurement function with the "FUNC."
button. The display will show “m”, “OL”, and the “W” symbol.
2. Insert the red probe in the “ ” socket and insert the black
probe in the “COM” socket.
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.
