tions and in the positions specified by the manufacturer,
without the product‘s ventilation being obstructed. If the
manufacturer‘s specifications are not observed, this can
result in electric shock, fire and/or 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: industrial sector, home, business and
commercial sectors, small businesses. The measuring
instrument is designed for indoor use only. Before each
measurement, you need to verify at a known source if the
measurement instrument functions properly.
1 .6 Ambient conditions
The allowed operating temperature ranges from +5 °C to
+40 °C (pollution category 2). The maximum relative hu-
midity (without condensation) is at 80%. During storage
and transport, the temperature must 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 prior
to operation. The 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 exists or with
aggressive chemical agents. Any operating position may
be used; however, adequate air circulation must be main-
tained. For continuous operation, a horizontal or inclined
position (integrated stand) is preferable. The maximum
operating altitude for the instrument is 2000 m. Specifica
-
tions with tolerance data apply after a warm up period of at
least 30 minutes at a temperature of 23 °C (tolerance ±2°C).
Specifications without tolerance data are average values.
1 .7 Warranty and repair
ROHDE & SCHWARZ instruments are subject to strict
quality controls. Prior to leaving the manufacturing site,
each instrument undergoes a 10-hour burn-in test. This is
followed by extensive functional quality testing to examine
all operating modes and to guarantee compliance with
the specified technical data. The testing is performed with
testing equipment that is calibrated to national standards.
The statutory warranty provisions shall be governed by
the laws of the country in which the ROHDE & SCHWARZ

back panel has to be unplugged.

product was purchased. In case of any complaints, please
contact your supplier.
Any adjustments, replacements of parts, maintenance or
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 swit-
ches, 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 to ensure the continued safety
of the product.
1 .8 Maintenance
The display may only be cleaned with water or appropriate
glass cleaner (not with alcohol or other cleaning agents).
Follow this step by rubbing the display down with a dry,
clean and lint-free cloth. Do not allow cleaning fluid to
enter the instrument. The use of other cleaning agents
may damage the labeling or plastic and laquered sur-
faces.
1 .9 Measuring Category
This oscilloscope is designed for measurements on circuits
that are only indirectly connected to the mains or not
connected at all. The instrument is not rated for any mea-
surement category. Make sure the entry voltage of the
analog channels CH1/CH2 does not exceed 200 V (peak
value),150 V
RMS
at 1 MΩ input impedance. The entry vol
-
tage of the external trigger input (TRIG. EXT.) does not
exceeded 100 V (peak value).The maximum value allowed
for transient overvoltages is 200 V (peak value). To ensure
compliance, it is necessary to only use probes that have
been manufactured and tested in accordance with DIN EN
61010-031in order to prevent transient overvoltages at the
measurement input. The auxilary output (AUX OUT) is a
multi-purpose output with the function as component tes-
ter, trigger output, pass/fail and function generator. 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 instru-
ment. Direct measurements (without galvanic isolation) to
category II, III or IV circuits are prohibited. The measuring
Clean the outer case of the instrument at regular intervals, using
a soft, lint-free dust cloth. Before cleaning the instrument, please
make sure that it has been switched off and disconnected from
all power supplies. (e.g. mains or battery supply).
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)!
The product may only be opened by authorized and
qualified personnel. Before any work is performed on the
product or before the product is opened, it must be dis-
connected from the AC supply network. Otherwise, per-
sonnel will be exposed to the risk of an electric shock.
