The existing categories according EN 61010-1 are: CAT

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.

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

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)DVM010

V. 01 – 09/05/2023 8 ©Velleman Group nv

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)
