When measuring currents up to 10A, max. 10s continuous

measurement followed by a 15 minutes break between 2

measurements.

When carrying out measurements on a TV set or switching power

circuits, always be aware that high amplitude voltage pulses at the

Switch off the meter and remove test probes prior to replacing the

battery or fuses.

All modifications of the device are forbidden for safety reasons.

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 which are not directly connected to mains power, e.g. electronics

circuits, control si

nals…

CAT II

A CAT II-rated meter is suitable for measurements in CAT I-environments

and mono-phase appliances which are connected to the mains by means of

a plug and circuits in a normal domestic environment, provided that the

circuit is at least 10m apart from a CAT III- or 20m apart from a CAT IV-

environment. E.

. household a

liances,

ortable 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 10m apart from of a CAT IV-

environment, and for measurements in or on distribution level equipment

(

fuse boxes, li

htin

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 600V. 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 suitable for measurements up to 600V on:

• Protected electronic circuits which are not directly connected to mains power,

e.g. electronics circuits, control signals, circuits behind isolating transformer…

• circuits which are directly connected to mains power, but limited to:
