Safety Features and Precautions
You have selected an instrument which provides you with a
high level of safety.
This instrument fulfills the requirements of the applicable
European and national EC guidelines. We confirm this with
the CE marking. The relevant declaration of conformity can
be obtained from GMC-I Gossen-Metrawatt GmbH.
The precision digital multimeter is manufactured and tested
in accordance with safety regulations IEC 61010–1:2001/
DIN EN 61010–1:2001/ VDE 0411–1:2002. When used for
its intended purpose, safety of the operator, as well as that
of the instrument, is assured. Their safety is however not
guaranteed, if the instrument is used improperly or handled
carelessly.
In order to maintain flawless technical safety conditions,
and to assure safe use, it is imperative that you read the
operating instructions thoroughly and carefully before plac-
ing your instrument into service, and that you follow all
instructions contained therein.
For your safety, as well as for the protection of your instru-
ment, the multimeter is equipped with an automatic socket
blocking device. This is coupled to the rotary switch, and
only allows connection to the socket required for the
selected function. It also prevents the switching of the
rotary selector to disallowed functions when a measure-
ment cable is plugged into a socket. Exception METRA
HIT 29S: in switch position W/mA or W/A jack V remains
open for power measurement, in position W/A jack mA is
only partially covered or blocked.
Use for Intended Purpose:
