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 III installations when measuring voltages
that might exceed the safety margin of 600 V above earth ground.
Never use the meter with CAT IV 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.

•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 testing continuity, diodes and batteries.
Refer to the illustration on page 2 of this manual:
1. Display
3 ½ digits, 7 segments, LCD: 61 x 32 mm
2. Selection buttons
3. On-off switch
This switch is used to turn the meter on/off.
4. “15A”jack
Insert the red test lead in this connector in order to measure a max.
current of 15 A.
5. “mA” jack
Insert the red (positive) test lead in this connector to measure current
(except 15 A).
6. “COM” jack
Insert the black (negative) test lead.
7. “V”jack
Insert the red (positive) test lead in this connector to measure voltage
and resistance.
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…

DVM101
V. 02 –02/12/2019 7 ©Velleman nv
CAT
II
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
IV
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 III 600 V and CAT IV 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 600 V in
CAT III and up to 300 V in CAT IV
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)

DVM101
V. 02 –02/12/2019 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.
9. Specifications
IMPORTANT: This device cannot measure positive voltages < 2 V. Manual
mV setting is not possible.
