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. 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

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 600 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 II

7. 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)

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.
