GB | Digital Multimeter

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

A

B

4

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.

5

• 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!

connect the multimeter to voltage higher than 600 V AC/DC CAT III

and 750 V AC/1000 V DC CAT II.

Alternating Current/Direct Current Measurement

Note:

When measuring current up to 600 mA, connect the plug of the

black (negative) tipped measuring conductor into the COM socket

and the plug of the red (positive) conductor for measuring voltage

into the µA/mA socket. Switch to the function marked as or

and select the range.

13

Repeatedly pressing the Select button switches between measuring

direct current (DC) or alternating current (AC). When measuring cur-

rent up to 10 A, rst select the measuring range and then connect

the plug of the black (negative) tipped measuring conductor into the

COM socket and the plug of the red (positive) for measuring voltage

into the 10 A socket. If you do not know the current range beforehand,

leave the range setting on AUTO or set the highest range possible

and gradually reduce it as you measure. Connect the measuring

tips to the device or circuit where you will be measuring current.

Turn on the device you want to measure. The screen will display the

current value and polarity (for DC) relative to the red measuring tip.

If „OL“ appears on the screen while in manual mode, set a higher

range.

Current Measurement

(WH3303 or DM633 Measuring Clamp – Optional Accessory)

To measure alternating current over 10 A, it is necessary to use an

AC measuring clamp.

1. Connect the plug of the black (negative) tipped measuring

conductor into the COM socket and the plug of the red (positive)

conductor into the INPUT socket.

2. Switch to the function.

3. Measurement with clamps is done by gripping the measured

conductor with the centre of the clamp.

Only one conductor can be measured at a time.

The measured current value will appear on the screen.

Note: Unifying deviation in measurement sensitivity

1. The sensitivity of measurement using the clamp is 1 A/1 mV. If

you are using a clamp with this sensitivity, then the listed value

is identical to the measured value.

2. When using a clamp with sensitivity other than 1 A/1 mV, the

measured value should be multiplied based on the sensitivity

of the clamp.

Do not touch the measured circuit with your hand or other part

of the body.

Note:

1. When measuring resistances higher than 1 MΩ, it is necessary

to wait a few seconds before the measured value stabilizes.

2. If the circuit is open, the „OL“ symbol will appear, same as when

the measuring range is exceeded. Before measuring resistance,

make sure that the measured object is disconnected from power

supply and all its capacitors are fully discharged.

Diode Measurement

Connect the plug of the black (negative) measuring conductor into

the COM socket and the plug of the red (positive) measuring tip for

measuring diodes into the INPUT socket. Switch to the function

marked with . Press the Select button repeatedly to select the

function. Connect the red measuring tip onto the diode‘s anode

and the black measuring tip onto the diode‘s cathode. Approximate

voltage in the direction of the ow of current will appear on the

screen. „OL“ will appear on the screen if the polarity is reversed.

15

Transistor Measurement (Amplication)

1. Switch to the hFE function.

2. Connect an adapter for measuring transistors into the COM

(minus) socket and the INPUT (plus) socket according to gure

2. make sure the connection is correct!

3. Before you measure, determine whether the transistor has an

NPN or PNP junction and identify the base, emitter and collec-

tor. Connect the outlets from the transistor into the marked

openings in the adapter.

object. The object must not be live; be mindful of any rotating

parts on various devices. The screen will show the measured

temperature after a few moments.

Note:

The type K thermocouple included with the multimeter is designed

for measuring temperatures between -20°C and 300°C. Measuring

temperatures above 300°C may cause damage to the thermocouple

and the multimeter! If you want to measure higher temperatures,

use a dierent thermocouple with a higher measurement range!

Capacity Measurement

1. Connect the plug of the black (negative) tipped measuring

conductor into the COM socket and the plug of the red (positive)

measuring tip for measuring capacity into the INPUT socket.

2. Switch to the function.

16

3. Place the measuring tips onto the measured object (capacitor).

If it is e.g. an electrolytic capacitor, make sure to observe correct

polarity during measurement. (the red measuring cable should

be connected to the capacitor‘s positive pole, the black to the

negative pole).

The capacity value will appear on the screen.

Note:

When the capacity range is low, the displayed capacity value may

be unstable. In that case, the measuring tips were not connected

to the object (capacitor). This is normal behaviour and does not

aect measurement.

If the measured value is over 600 μF, it takes at least 10 seconds

for the value to stabilise.

Frequency and Duty Cycle Measurement

1. Connect the plug of the black (negative) tipped measuring

conductor into the COM socket and the plug of the red (positive)

measuring tip into the INPUT socket.

2. Switch to the function.

3. Connect the measuring tips to the object you want to measure.

4. Repeatedly press the Hz/Duty button to select voltage/cur-

rent frequency measurement or voltage/current duty cycle

measurement.
