1 .2 Unpacking
While unpacking, check the package contents for com-
pleteness (measuring instrument, power cable, possibly
optional accessories). After unpacking, check the
instrument for mechanical damage occurred during
transport and for loose parts inside. In case of transport
damage, please inform the supplier immediately. The inst-
rument must not be operated in this case.
1 .3 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 .4 Safety
This instrument was built in compliance with DIN EN
61010-1 (VDE 0411 part 1), safety regulations for electrical
measuring instruments, control units and Iaboratory equip-
ment. It has been tested and shipped from the plant in safe
condition. It is in compliance with the regulations of the
European standard EN 61010-1 and the international stan-
dard IEC 61010-1. To maintain this condition and to ensure
safe operation, the user must observe all instructions and
warnings given in this operating manual. Casing, chassis
and all measuring ports are connected to a protective Fig.
1.1: Operating positions earth conductor. The instrument is
designed in compliance with the regulations of protection
class I. 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 connec-
ted. 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
does not meet the minimum requirements by post office,
railway or forwarding agency).
1 .5 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-
It is prohibited to disconnect the earthed protective
connection inside or outside the instrument!
Use the measurement instrument only with original ROHDE &
SCHWARZ measuring equipment, measuring cables and power
cord. Never use inadequately measured power cords. Before each
measurement, measuring cables must be inspected for damage
and replaced if necessary. Damaged or worn components can
damage the instrument or cause injury..
