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 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.

• This device is suitable for measurements up to 600V in CAT II:

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 10m apart from

a CAT III- or 20m apart from a CAT IV-environment. E.g. household

appliances, portable tools…

5. General Guidelines

Refer to the Velleman

Service and Quality Warranty on the last pages

of this manual.

• Familiarise yourself with the functions of the device before actually using

any ensuing defects or problems.

• Protect this device from shocks and abuse. Avoid brute force when

operating.

• Protect the device against extreme heat (e.g. direct sunlight) and dust.

• Do not store or use the devices in places with high humidity or

temperature, places where combustible or explosive gasses reside or near

strong magnetic fields.

• Caution: risk of electroshock when measuring voltages > 36VDC, 25VAC,

currents > 10mA, AC power lines with inductance load and AC power lines

with fluctuating power.

• Only use the included test leads. When damaged, replace them with test

leads of the same type and with the same specifications.

• Always verify that all connections are reliable and safe.

• Before measuring, always check the selected range.

• 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.
