Before changing functions or measuring range, disconnect the test leads

from the circuit under test.

For all DC functions, to avoid the risk of shock due to possible improper

readings, verify the presence of any AC voltages first by using the

AC function. Then select a DC voltage range equal to or greater than

the AC range.

Use 2 x 1.5 V AAA type batteries, properly installed in the meter‟s

battery case, to power the meter.

Replace the battery as soon as the battery indicator appears. With

a low battery, the meter may produce false readings that can lead to

electric shock and personal injury.

Do not operate the meter with the case (or part of the case) removed.

Always verify that all connections are reliable and safe.

Avoid body contact with ground potential (e.g. metallic terminals,

output sockets, lead clamp…) while measuring. Make sure to be

electrically insulated from ground during measurement.

4. 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…

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 33 ft (10 m) apart

from a CAT III, or 66 ft (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 33 ft (10 m)

apart from 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.

environments.

5. 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 DMM 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).

DVM630

V. 01 –22/04/2013 8 ©Velleman Inc.

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).

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.
