Important Notes
❙The instrument is no longer working
❙After an extended period of storage under unfavorable
conditions (e.g. outdoors or in damp rooms)
❙Rough handling during shipment
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 prod-
uct may have to be changed accordingly.
1.6 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.
The product may be operated only under the operating
conditions and in the positions specified by the manufac-
turer, 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 in-
jury, 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.
1.7 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.
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.
To disconnect from the mains, the low-heat device socket on the
back panel has to be unplugged.
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 reference
values of an average instrument.
1.8 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-
ified technical data. The testing is performed with testing
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.
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.
1.9 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-
ing fluid to enter the instrument. The use of other cleaning
agents may damage the labeling or plastic and lacquered
surfaces.
Do not obstruct the ventilation holes!
The product may only be opened by authorized and
qualified 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.
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)!
