General Guidelines - Velleman DVM870 Bedienungsanleitung

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...

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.
