serious personal injury, 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. The measuring instrument is designed for use
in the following sectors: Industry, residential, business and
commercial areas and small businesses. The measuring
instrument is designed for indoor use only. Before each
measurement, you need to verify at a known source if the
measuring instrument functions properly.
1.6 Ambient conditions
Permissible operating temperatures during the operations
range from +5 °C to +40 °C. During storage or transporta-
tion the temperature may be between –20 °C and +70 °C.
In case of condensation during transportation or storage ,
the instrument will require approximately two hours to dry
and reach the appropriate temperature. It can then be op-
erated. The measuring instrument is designed for use in
a clean and dry indoor environment. Do not operate with
high dust and humidity levels, if danger of explosion ex-
ists or with aggressive chemical agents. Any operating po-
sition may be used; however adequate air circulation must
be maintained. For continuous operation, a horizontal or
inclined position (integrated stand) is preferable.
The maximum operating altitude for the instrument is
2000m. Nominal data with tolerance details apply once
the ambient temperature of 23 °C has been reached after
about 30 minutes. Values without tolerance details are ref-
erence values of an average instrument.
1.7 Warranty and repair
ROHDE & SCHWARZ instruments are subject to strict qual-
ity controls. Prior to leaving the manufacturing site, each in-
strument undergoes a 10-hour burn-in test. This is followed
by extensive functional quality testing to examine all oper-
ating modes and to guarantee compliance with the spec-
iedtechnicaldata.Thetestingisperformedwithtesting
equipment that is calibrated to national standards. The stat-
utory warranty provisions shall be governed by the laws of
the country in which the ¸ product was purchased. In
case of any complaints, please contact your supplier.
To disconnect from the mains, the low-heat device socket on the
back panel has to be unplugged.
Do not obstruct the ventilation holes!
The product may only be opened by authorized and
qualied personnel. Prior to working on the product or
before the product is opened, it must be disconnected
from the AC supply network. Otherwise, personnel will
be exposed to the risk of an electric shock.
Any adjustments, replacements of parts, maintenance
and repair may be carried out only by authorized ROHDE
& SCHWARZ technical personnel. Only original parts may
be used for replacing parts relevant to safety (e.g. power
switches, power transformers, fuses). A safety test must al-
ways be performed after parts relevant to safety have been
replaced (visual inspection, PE conductor test, insulation
resistance measurement, leakage current measurement,
functional test). This helps ensure the continued safety of
the product.
1.8 Maintenance
The display may only be cleaned with water or an ap-
propriate glass cleaner (not with alcohol or other clean-
ing agents). Follow this step by rubbing the display down
with a dry, clean and lint-free cloth. Do not allow clean-
inguidtoentertheinstrument.Theuseofothercleaning
agents may damage the labeling or plastic and lacquered
surfaces.
1.9 Measurement categories
This oscilloscope is designed for measurements on cir-
cuits that are only indirectly connected to the mains or
not connected at all. Make sure the entry voltage of the
analog channels CH1/CH2 does not exceed 200 V (peak
value),150V
RMS
at1MΩandand5V
RMS
at50Ωinputim-
pedance. The entry voltage of the external trigger in-
put (TRIG. EXT.) does not exceeded 100V (peak value).
The maximum value allowed for transient overvoltages is
200V (peak value). To ensure compliance, it is necessary
to only use probes that have been manufactured and tes-
ted in accordance with DIN EN 61010-031in order to pre-
vent transient overvoltages at the measurement input.
When performing measurements in category II, III or IV
circuits, it is mandatory to insert a probe that reduces the
voltage so that no transient overvoltages will be applied
to the instrument. Direct measurements (without galva-
nic isolation) to category II, III or IV circuits are prohibi-
ted. The measuring circuits are considered not connec-
ted to the mains if an isolation transformer in compliance
with class II is used. It is also possible to perform mea-
surements on the mains if appropriate transformers (e.g.
current connectors) are used that are in compliance with
safety class II. The measurement category (for which the
manufacturerspeciedtherequiredtransformer)mustbe
observed.
Clean the outer case of the measuring instrument at regular in-
tervals, using a soft, lint-free dust cloth.
Before cleaning the measuring instrument, please make sure that
it has been switched off and disconnected from all power sup-
plies (e.g. AC supply network or battery).
No parts of the instruments may be cleaned with chemical clean-
ing agents (such as alcohol, acetone or cellulose thinner)!
