The advantage of a fully automatic multimeter is that
during the measurement the device automatically detects
which function is needed and performs the measurement
in. You can use the sensor on the top of the device to detect
voltage without breaking the wiring. It is characterized
by an ergonomic housing, compact size and easy
handling. The practical carrying case protects the product
during transport.

afety warnings
• To reduce the risk of electric shock or personal injury,
follow these instructions:
• Never use the instrument if it is damaged. Check the
integrity of the cover before use. Pay special attention to
the insulation of the contacts.
• Check the insulation of the test leads or that they do not
come into contact with metal. Replace the test leads if
they are damaged.
• Do not use the instrument if it operates abnormally.
If in doubt about the usage of the device, take it to
a service center.
• Do not use the device in the presence of flammable,
explosive gases, vapors and dusts.
• Never measure more than the maximum permissible
measuring range.
• Check the operation of the padlock on a known circuit
before use.
• When repairing the device, always use the parts
recommended by the manufacturer.
• Measure with extreme caution at 30 V AC RMS, 42 V peak,
or 60 V DC, as it could easily cause severe electric shock.
• If you use an additional probe, make sure that your fingers
are behind the metal part of the probe in the insulated
area during the measurement.
• Connect the secondary test lead (black) first to the object
to be measured, then to the primary (red). When the
measurement is completed, disconnect the primary from
the circuit first and then the secondary.
• Always remove the test leads before opening the
battery cover.
• Never use the instrument with the battery cover open or
the housing damaged.
• To avoid errors in measurement results or possible
personal injury („leaking current”), replace the battery
in the device as soon as possible if the icon appears
on the display.
• When using the padlock portion of the instrument,
remove the test leads.
• Remove the padlock jaws from the circuit before opening
the battery cover.
• CATIII - Contact protection measurement category III - can
be used for indoor measurements, such as distribution
cabinets, circuit breakers, wires, busbars, junction boxes,
switches, sockets in a fixed design and for other industrial
applications, such as fixed connection of installed motors.
Do not use the instrument for CAT IV measurements!
attention!
To avoid damage to the device, always follow the
instructions below:
Turn off the power source or discharge the high capacity
capacitors before measuring resistance, diode or continuity.
Only perform measurements within the measuring range
of the device.
Do not connect to the circuit or object to be measured
when turning the function selector knob.
