❙ 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

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.
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.
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.
To disconnect from the mains, the low-heat device socket on the
back panel has to be unplugged.

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 reference
values of an average instrument.
Do not obstruct the ventilation holes!

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. Nearly
every premature failure will be detected in intermittent op-
eration. 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 RO-
HDE & SCHWARZ product was purchased. In case of any
complaints, please contact your supplier.
Applicable only in EU countries:
If your instrument still requires repair work, customers
within the EU can process repairs directly with HAMEG to
accelerate the procedures. The HAMEG customer service
(see RMA) is available for repair services even once the
warranty 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 require technical support or suitable pack-
aging (original box), please contact the HAMEG Service:

The product may only be opened by authorized and qual-
ified personnel. Prior to working on the product or be-
fore the product is opened, it must be disconnected from
the AC supply network. Otherwise, personnel will be ex-
posed 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
always be performed after parts relevant to safety have
been replaced (visual inspection, PE conductor test, insu-
lation resistance measurement, leakage current measure-
ment, functional test). This helps ensure the continued
safety of the product.
