4. Maintenance

There are no user-serviceable parts inside the device.

Refer to an authorized dealer for service and/or spare parts.

Before performing any maintenance activities, disconnect the test leads

from the jacks.

For instructions on replacing battery or fuse, refer to §11 Battery and fuse

replacement.

Do not apply abrasives or solvents to the meter. Use a damp cloth and mild

detergent for cleaning purposes.

5. During Use

Risk of electric shock during operation. Be very careful when

measuring live circuits.

•Never exceed the limit value for protection. This limit value is listed

separately in the specifications for each range of measurement.

•Do not touch unused terminals when the meter is linked to a circuit

which is being tested.

•Never use the meter with CAT II installations when measuring voltages

that might exceed the safety margin of 500 V above earth ground.

Never use the meter with CAT III installations when measuring voltages

that might exceed the safety margin of 300 V above earth ground.

•Set the range selector at its highest position if the intensity of the

charge to be measured is unknown beforehand.

•Disconnect the test leads from the tested circuit before rotating the

range selector in order to change functions.

•When carrying out measurements on a TV set or switching power

circuits, always remember that the meter may be damaged by any high

amplitude voltage pulses at test points.

DVM841

V. 03 –08/07/2020 6 ©Velleman nv

•Always be careful when working with voltages above 60 VDC or 30 VAC

rms. Keep your fingers behind the probe barriers at all times during

measurement.

•Never perform resistance, diode or continuity measurements on live

circuits. Make sure all capacitors in the circuit are depleted.

6. General Description

This device is a battery-operated, hand-held 3 ½ digital multi-meter for

measuring DC and AC voltages, DC current and resistance. It also offers the

possibility of executing continuity tests and of testing diodes and transistors.

The back light is optional.

Refer to the illustration on page 2 of this manual:

1. Display

3 ½ digits, 7 segments, LCD: 47 x 15 mm

2. Back light

In any range, press this button to activate the backlight. Press again to

deactivate.

3. Rotary switch

This switch is used to select functions and desired ranges as well as to

turn the meter on/off.

4. Hold button

In any range, press this button to freeze the last reading. Press again

to unfreeze.

5. "VmA" jack

Insert the red (positive) test lead in this connector to measure voltage,

resistance and current (except 10 A).

6. "COM" jack

Insert the black (negative) test lead.

7. "10A" jack

Insert the red test lead in this connector in order to measure a max.

current of 10 A.

7. Overvoltage/Installation Category

DMMs are categorized depending on the risk and severity of transient

overvoltage that might occur at the point of test. Transients are short-lived

bursts of energy induced in a system, e.g. caused by lightning strike on a

power line.

The existing categories according EN 61010-1 are:

CAT I

A CAT I-rated meter is suitable for measurements on protected

electronic circuits that are not directly connected to mains power,

e.g. electronics circuits, control signals…

DVM841

V. 03 –08/07/2020 7 ©Velleman nv

CAT

A CAT II-rated meter is suitable for measurements in CAT I-

environments and mono-phase appliances that are connected to the

mains by means of a plug and circuits in a normal domestic

environment, provided that the circuit is at least 10 m apart from a

CAT III- or 20 m apart from a CAT IV-environment. E.g. household

appliances, portable tools…

CAT

III

A CAT III-rated meter is suitable for measurements in CAT I- and

CAT II-environments, as well as for measurements on (fixed) mono-

or poly-phased appliances which are at least 10 m apart from of a

CAT IV-environment, and for measurements in or on distribution

level equipment (fuse boxes, lighting circuits, electric ovens).

CAT

A CAT IV-rated meter is suitable for measuring in CAT I-, CAT II-

and CAT III-environments as well as on the primary supply level.

Note that for all measurements on equipment for which the supply

cables run outdoors (either overhead or underground) a CAT IV

meter must be used.

Warning:

This device was designed in accordance with EN 61010-1 installation

category CAT II 500 V and CAT III 300 V. This implies that certain

restrictions in use apply that are related to voltages and voltage peaks

which can occur within the environment of use. Refer to the table above.

This device is only suitable for measurements up to 500 V in

CAT II and up to 300 V in CAT III

8. Pollution Degree

IEC 61010-1 specifies different types of pollution environments, for which

different protective measures are necessary to ensure safety. Harsher

environments require more protection, and the protection against the

pollution which is to be found in a certain environment depends mainly on

the insulation and the enclosure properties. The pollution degree rating of

the DVM indicates in which environment the device may be used.

Pollution

degree 1

No pollution or only dry, nonconductive pollution occurs. The

pollution has no influence. (only to be found in hermetically

sealed enclosures)

Pollution

degree 2

Only nonconductive pollution occurs. Occasionally,

temporary conductivity caused by condensation is to be

expected.(home and office environments fall under this

category)

DVM841

V. 03 –08/07/2020 8 ©Velleman nv

Pollution

degree 3

Conductive pollution occurs, or dry nonconductive pollution

occurs that becomes conductive due to condensation that is

to be expected.

(industrial environments and environments exposed to

outside air - but not in contact with precipitation)

Pollution

degree 4

The pollution generates persistent conductivity caused by

conductive dust or by rain or snow. (exposed outdoor

environments and environments where high humidity levels

or high concentrations of fine particles occur)

Warning: This device was designed in accordance with EN 61010-1

pollution degree 2. This implies that certain restrictions in use apply that

are related to pollution which can occur within the environment of use. Refer

to the table above.

This device is only suitable for measurements in Pollution

degree class 2 environments.
