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 in-
strument 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
TheinstrumentfullstheDINEN61010-1(VDE0411part
1) regulations for electrical measuring, control and labo-
ratory instruments and was manufactured and tested ac-
cordingly. It left the factory in perfect safe condition.
Hence it also corresponds to European Standard EN
61010-1 and Standard IEC 61010-1. In order to maintain
this condition and to ensure safe operation the user is re-
quired to observe the warnings and other directions for
use in this manual. Housing, chassis as well as all measur-
ing terminals are connected to safety ground of the mains.
The instrument is designed in compliance with the regu-
lations of protection class I. The exposed metal parts are
checked against the mains poles with 2200 VDC voltage.
The instrument is in accordance 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. Sep-
arating the grounds is prohibited. 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 in-
strument must be shut down and secured against any un-
intended 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).
1.5 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 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
operatingconditionsandinthepositionsspeciedbythe
It is prohibited to disconnect the earthed protective
connection inside or outside the instrument!
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 components can
damage the instrument or cause injury.
