General Information and Safety
The measuring instrument is designed for use in the fol-
lowing sectors: industrial sector, home, business and com-
mercial 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.
1.5 Ambient Conditions
The allowed operating temperature ranges from +0 °C to
+55 °C (pollution category 2). The maximum relative hu-
midity (without condensation) is at 80%. During storage
and transport, the temperature must be between –40 °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. Specifications with tolerance data apply after a
warm up period of at least 90 minutes at a temperature of
23 °C (tolerance ±2°C). Specifications without tolerance
data are average values.
1.6 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 test-
ing 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 product
was purchased. In case of any complaints, please contact
your supplier.
Applicable only in EU countries:
To accelerate claims, customers in EU countries may also
contact HAMEG directly for repairs. The HAMEG customer
service is available for repair services even once the war-
ranty period ends.
Return Material Authorization (RMA):
In any event, before returning an instrument, request
a RMA number either via Internet (http://www.hameg.
com) or by fax. If you need technical support or a suitable
original packaging, please contact the HAMEG service
department:
To disconnect from the mains, the low-heat device socket on the
back panel has to be unplugged.

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
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 to ensure the continued safety
of the product.
1.7 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.
1.8 CAT II
This instrument is designed for measurements on circuits
that are either directly connected to the low voltage mains
or not connected at all. The instrument is in accordance
with measurement category CAT II; the input voltage may
not exceed 600 V (peak value) in a CAT II application.
The following information refers solely to user safety. Other
aspects, such as the maximum input voltage, are descri-
bed in the technical data and must also be observed. It is
also possible to perform measurements on the mains if
appropriate transformers (e.g. current connectors) are used
that are at least in compliance with the safety class of the
measurement to be performed. The measurement category
(for which the manufacturer specified the required transfor-
mer) must be observed.
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
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 inter-
vals, 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 supplies
(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)!
