1.2 Setting up the instrument
As you can see from the picture, there are small feets on
the bottom which can be folded out. Please make sure you
have fully folded out the feet‘s in order to ensure stability
of the instrument.
The instrument must be installed in a way, that at any time
the disconnection of the power line is not restricted.
1.3 Safety
TheinstrumentfullstheDINEN61010-1(VDE0411part
1) regulations for electrical measuring, control and labora-
tory instruments and was manufactured and tested accor-
dingly. It left the factory in perfect safe condition. Hence it
also corresponds to European Standard EN 61010-1 and In-
Fig. 1.1: Operating positions
ternational Standard IEC 61010-1. In order to maintain this
condition and to ensure safe operation the user is required
to observe the warnings and other directions for use in
this manual. Housing, chassis as well as all measuring ter-
minals are connected to safety ground of the mains. The
instrument is designed in compliance with the regulations
of class I.
The exposed metal parts are checked against the mains
poles with 2200 V
DC
voltage. The instrument is in ac-
cordance with overvoltage category II. For safety reasons,
the instrument may only be operated with authorized
safety sockets. The power cord must be plugged in before
signal circuits may be connected. Separating the grounds
is prohibited.
Never use the product if the power cable is damaged.
Check regularly if the power cables are in perfect condi-
tion. Choose suitable protective measures and installation
types to ensure that the power cord cannot be damaged
and that no harm is caused by tripping hazards or from
electric shock, for instance. If it is assumed that a safe
operation is no longer possible, the instrument must be
shut down and secured against any unintended operation.
Safe operation can no longer be assumed:
❙ in case of visible damage,
❙ in case loose parts were noticed,
❙ if it does not function any more,
❙ after prolonged storage under unfavourable conditions
(e.g. like in the open or in moist atmosphere),
❙ after rough handling during transport (e.g. packaging that
doesnotmeettheminimumrequirementsbypostofce,
railway or forwarding agency).
1.4 Intended Operation
The measuring instrument is intended only for use by per-
sonnel familiar with the potential risks of measuring electri-
cal quantities. For safety reasons, the instrument may only
be connected to properly installed safety socket outlets.
Separating the grounds is prohibited. The power plug must
be inserted before signal circuits may be connected. The
product may be operated only under the operating condi-
tionsandinthepositionsspeciedbythemanufacturer,
without the products ventilation being obstructed. If the

and in some cases, death. Applicable local or national
safety regulations and rules for the prevention of accidents
must be observed in all work performed.
Use the measurement instrument only with original HAMEG
measuring equipment, measuring cables and power cord. Never
use inadequately measured power cords. Before each measure-
ment, measuring cables must be inspected for damage and repla-
ced if necessary. Damaged or worn components can damage the
instrument or cause injury.
