Read this instruction manual thoroughly before you begin using

the M0430. 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/CAT II 1000 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.

Category CAT II is intended for measurements made on circuits

directly connected to low-voltage installations (e.g. household

appliances, portable tools and similar equipment).

Do not use the multimeter to measure ranges that fall into the

category IV!

Warning:

Use the M0430 multimeter only in the manner specied 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 1000 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 specications. 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 qualied 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 batteries

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 (9 V, type 1604 or 6F22) and make sure to observe the correct

polarity. Replace the rear casing.
