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…

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…

DVM898

V. 03 – 06/04/2021 7 ©Velleman nv

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)

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)

Voor informatie over het vervangen van de batterijen en de zekering, zie

§11 Batterijen en zekeringen vervangen.

Gebruik nooit agressieve schuur- of oplosmiddelen. Reinig de meter enkel

met een vochtige doek en een zachte detergent.

5. Tijdens het gebruik

Elektrocutiegevaar tijdens het gebruik van deze multimeter.

Wees voorzichtig tijdens het meten van een circuit onder spanning.

• Overschrijd nooit de grenswaarden. Deze waarde wordt afzonderlijk in

de technische gegevens van elk meetbereik vermeld.

• Raak geen ongebruikte aansluitingen aan wanneer de meter gekoppeld

is aan een meetcircuit.

• Gebruik de meter nooit voor categorie III-installaties bij

spanningsmetingen die de veiligheidsmarge van 600 V boven het

massapotentiaal (kunnen) overschrijden.

Gebruik de meter nooit voor categorie IV-installaties bij

spanningsmetingen die de veiligheidsmarge van 300 V boven het

massapotentiaal (kunnen) overschrijden.

• Plaats de bereikschakelaar in de hoogste stand indien u de intensiteit

van de belasting niet op voorhand kent.

• Ontkoppel de meetsnoeren van het meetcircuit alvorens u aan de

draaischakelaar draait.

• Wanneer u metingen uitvoert op een tv of een schakelende voeding,

mag u niet vergeten dat een sterke stroomstoot ter hoogte van de

geteste punten de meter kan beschadigen.

• Wees uiterst voorzichtig bij metingen > 60 VDC of > 30 VAC rms. Houd

tijdens metingen uw vingers achter de beschermingsrand van de

meetpennen.

• Voer nooit weerstands-, diode- of continuïteitsmetingen uit in circuits

waarop spanning aanwezig is. Zorg ervoor dat alle condensatoren in het

circuit volledig ontladen zijn.

7. “VHz”-bus

Sluit het rode meetsnoer (+) aan op deze bus om spanning, weerstand

en frequentie te meten.

7. Overspannings-/installatiecategorie

DMM’s worden opgedeeld volgens het risico op en de ernst van

spanningspieken die kunnen optreden op het meetpunt. Spanningspieken

zijn kortstondige uitbarstingen van energie die geïnduceerd worden in een

systeem door bv. blikseminslag op een hoogspanningslijn.

De bestaande categorieën volgens EN 61010-1 zijn:

CAT I

Een CAT I-meter is geschikt voor metingen op beschermde

elektronische circuits die niet rechtstreeks verbonden zijn met het

lichtnet, bv. elektronische schakelingen, stuursignalen…

CAT

II

Een CAT II-meter is geschikt voor metingen in CAT I-omgevingen en

op enkelfasige apparaten die aan het lichtnet gekoppeld zijn door

middel van een stekker en circuits in een normale huiselijke

omgeving, op voorwaarde dat het circuit minstens 10 m verwijderd is

van een CAT III-omgeving, en minstens 20 m van een CAT IV-

omgeving. Bv. huishoudapparaten, draagbaar gereedschap...

CAT

III

Een CAT III-meter is geschikt voor metingen in CAT I- en CAT II-

omgevingen, alsook voor metingen aan enkel- en meerfasige (vaste)

toestellen op meer dan 10 m van een CAT IV-omgeving, en metingen

in of aan distributiekasten (zekeringkasten, verlichtingscircuits,

elektrisch fornuis).
