Read this instruction manual thoroughly before you begin using
the M0230. It contains particularly important passages concerning
occupational safety principles when using the device. Such passages
are highlighted. Reading the manual will prevent potential injury by
electric current or damage to the device.
The multimeter was designed in accordance with standard EN
61010-1, applying to electronic measuring instruments belonging
to category CAT III 600 V, pollution degree 2. CAT III is intended for
measuring circuits powered by xed wiring installations, such as
relays, sockets, distribution boxes, feeder lines and short branching
circuits and lighting systems in large buildings.
Do not use the multimeter to measure ranges that fall into the
category IV!
Warning:
Use the M0230 multimeter only in the manner specied below. Other
uses may cause damage to the device or endanger your health.
Comply with the following instructions:
• Before measuring resistance, diodes or current, disconnect the
circuits from the power supply and discharge any high-voltage
capacitors. Use a function appropriate for the given measure-
ment. Before changing the range (or switching functions) dis-
connect the conductors from the circuit that is being measured.
• Make sure the device is undamaged before you begin using the
multimeter. If you nd obvious signs of damage on the body of
the device, do not make any measurements! Check that the
surface of the multimeter does not have scratches and that the
side joints are not coming apart.
• Also check the insulation on the measuring probes. Damaged
insulation may result in injury by electric current. Do not use
damaged measuring probes!
• Do not measure voltages above 600 V! If you intend to measure
current, check the multimeter‘s fuse and turn o the power
supply to the circuit before you connect the multimeter. Before

measuring, make sure the circular switch for setting measuring
range is in the correct position. Under no circumstances should
you make any changes to the measuring range (by moving the
circular switch for changing measuring programmes) while
measuring! Doing so could damage the device. When you are
measuring, rst connect the black conductor (probe) and then
the red conductor (probe). When disconnecting the testing
conductors, disconnect the red one rst.
• If you nd that the multimeter is making abnormal measure-
ments, stop using it. The fuse may be damaged. If you are unsure
of the cause of the defect, contact a service centre.
• Do not measure voltages higher than listed on the front panel
of the multimeter. Risk of injury by electric current or damage
to the multimeter!
• Check that the multimeter is working properly before use. Test
on a circuit with known electrical values.
• Before you connect the multimeter to a circuit you intend to
measure, turn o the power to the circuit.
• Do not use or store the multimeter in environments with high
temperature, dust or humidity. It is also not recommended to
use the device in environments with potentially strong magnetic
elds or risk of explosion or re.
• When changing parts of the multimeter (e.g. the battery or fuse)
use spare parts of the same type and specications. Change
parts only when the multimeter is disconnected and turned o.
• Disconnect the testing conductors from the tested circuit before
opening the rear casing of the device.
• Do not alter or otherwise interfere with the internal circuitry
of the multimeter!
• Be extra careful when measuring voltages higher than 30 V AC
rms, 42 V peak or 60 V DC. Risk of injury by electric current!
• When using measuring tips, make sure you are holding them
behind the nger barriers.
• Do not perform measurements if the multimeter‘s casing is
removed or loose.

• Once the screen shows the low battery icon , replace the
batteries. Otherwise, subsequent measurements may be in-
accurate. Incorrect measurements may then result in injuries
by electric current! Use alkaline batteries only; do not use
re-chargeable batteries.
Maintenance Instructions
Attention
Do not attempt to repair or modify the multimeter in any way if you
are not qualied to do so or do not have access to the necessary
calibration equipment. Make sure that water does not get into the
multimeter – prevents injury by electric current!
• Disconnect the measuring tips from the tested circuit before
opening the casing of the multimeter.
• Regularly clean the body of the multimeter with a moist cloth and
a mild detergent. Perform cleaning only when the multimeter is
disconnected and turned o.
• Do not use solvents or abrasive agents for cleaning!
• If you will not be using the multimeter for an extended period
of time, turn it o and remove the battery.
• Do not store the multimeter in places with high humidity and
temperature or in environments with strong magnetic elds!
Changing Batteries
When the symbol appears on the screen, it indicates the bat-
teries are close to depletion and must be immediately replaced. To
replace the batteries, unfasten the screw at the rear of the casing
and remove the casing. Replace the at batteries with new ones of
the same type (1.5 V, AAA) and make sure to observe the correct
polarity. Replace the rear casing.
