1.2 Unpacking
While unpacking, check the package contents for com-
pleteness (measuring instrument, power cable, product
CD, 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
instrument must not be operated in this case.
1.3 Setting Up the Instrument
As shown in the illustrations, small hinges on the bottom
stands can be folded out to set up the instrument in a
slightly inclined position. Please make sure that the stands
are completely folded out to ensure a stable position.
The instrument must be positioned in a manner that allows
the user to disconnect the unit from the mains at any time
and without restrictions.
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, chas-
sis 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 connected. Never
use the product if the power cable is damaged. Check
regularly if the power cables are in perfect condition.
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:
❙If the measuring instrument shows visible damage
❙If the measuring instrument includes loose parts
❙If the measuring instrument no longer functions properly
❙After an extended period of storage under unfavorable
conditions (e.g. outdoors or in damp rooms)
❙After rough handling during transport (e.g. packaging
that does not meet the minimum requirements by post
office, railway or forwarding agency).
Prior to switching on the product, it must be ensured that
the nominal voltage setting on the product matches the
nominal voltage of the AC supply network. If it is neces-
sary to set a different voltage, the power fuse of the pro-
duct may have to be changed accordingly.
1.5 Intended Operation
The measuring instrument is intended only for use by
personnel familiar with the potential risks of measuring
electrical quantities. For safety reasons, the measuring
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.
It is prohibited to disconnect the earthed protective
connection inside or outside the instrument!
Exceeding the Low Voltage Protection!
For the series connection of all output voltages, it is pos-
sible to exceed the low voltage protection of 42 V. Please
note that in this case any contact with live components
is life-threatening. It is assumed that only qualified and
trained personnel service the power supplies and the
connected loads.
Use the measuring 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 compo-
nents can damage the instrument or cause injury.
