Setting up the product
Always place the product on a stable, flat and level surface with the bottom of the
product facing down. If the product is designed for different positions, secure the
product so that it cannot fall over.
If the product has foldable feet, always fold the feet completely in or out to ensure
stability. The feet can collapse if they are not folded out completely or if the prod-
uct is moved without lifting it. The foldable feet are designed to carry the weight of
the product, but not an extra load.
If stacking is possible, keep in mind that a stack of products can fall over and
cause injury.
If you mount products in a rack, ensure that the rack has sufficient load capacity
and stability. Observe the specifications of the rack manufacturer. Always install
the products from the bottom shelf to the top shelf so that the rack stands
securely. Secure the product so that it cannot fall off the rack.
Connecting to power and grounding
The mains power supply input of the instrument complies with overvoltage cate-
gory II. It has to be connected to a fixed installation used to supply energy-con-
suming equipment such as household appliances and similar loads. Be aware
that electrically powered products have risks, such as electric shock, fire, per-
sonal injury or even death.
Take the following measures for your safety:
●Do not use an isolating transformer to connect the instrument to the mains
power supply.
●Before switching on the product, ensure that the voltage and frequency indica-
ted on the product match the available power source. If the power adapter
does not adjust automatically, set the correct value and check the rating of the
fuse.
●Only use the power cable delivered with the product. It complies with country-
specific safety requirements. Only insert the plug into an outlet with protective
conductor terminal.
●If a product has an exchangeable fuse, its type and characteristics are indica-
ted next to the fuse holder. Before changing the fuse, switch off the instrument
and disconnect it from the power source. How to change the fuse is described
in the product documentation.

●Only use intact cables and route them carefully so that they cannot be dam-
aged. Check the power cables regularly to ensure that they are undamaged.
Also ensure that nobody can trip over loose cables.
●If the product needs an external power supply, use the power supply that is
delivered with the product or that is recommended in the product documenta-
tion or a power supply that conforms to the country-specific regulations.
●Ensure that you can disconnect the product from the power source at any
time. Pull the power plug to disconnect the product. The power plug must be
easily accessible. If the product is integrated into a system that does not meet
these requirements, provide an easily accessible circuit breaker at the system
level.
●Replace parts that are relevant to safety only by original parts, e.g. power
cables or fuses.
Performing measurements
Take the following measures for your safety:
●To ascertain voltage-free state, use an appropriate voltage tester. Any mea-
surement setup including an oscilloscope is not suitable for this purpose.
●The maximum input voltage on channel inputs and the external trigger input
must not exceed the value specified in the data sheet.
●Observe all voltage and current ratings of the instrument, the probes, and the
accessories. Exceeding the allowed voltages can lead to an electric shock.
Limits and ratings are marked on the products and listed in the data sheets.
Consider that the rated voltage depends on the frequency. The voltage limita-
tion curves or values are provided in the data sheet.
●Never cause any short circuits when measuring sources with high output cur-
rents.
●Use only probes and accessories that comply with the measurement category
(CAT) of your measurement task. The measurement category of the products
is defined in the data sheet. If you use other than Rohde & Schwarz accesso-
ries, make sure that they are suitable for the instrument and the measurement
task.
●Set the correct attenuation factor on the instrument according to the probe
being used. Otherwise, the measurement results do not reflect the actual volt-
age level, and you might misjudge the actual risk.
●When working with high voltages and current probes, observe the additional
operating conditions specified in this safety instructions.

●The probe pins are extremely pointed and can easily penetrate clothes and
the skin. Handle the probe pins with great care. To exchange a probe pin, use
tweezers or pliers to avoid injuries. When transporting the accessories, always
use the box supplied with the probe.
●Prevent the probe from receiving mechanical shock. Avoid putting excessive
strain on the probe cable or exposing it to sharp bends. Touching a broken
cable during measurements can cause injuries.
●Set up all probe connections to the instrument before applying power.
Working with hazardous voltages
Voltages higher than 30 V RMS, or 42 V peak, or 60 V DC are regarded as haz-
ardous contact voltages. Direct contact with them can cause serious injuries.
Make sure that only electrically skilled persons use the products for measure-
ments on hazardous contact voltages. These working conditions require special
education and experience to perceive risks and to avoid hazards which electricity
can create.
When working with hazardous contact voltages, use protective measures to pre-
clude direct contact with the measurement setup:
●Do not touch exposed connections and components when power is applied.
●Switch off the test circuit while connecting and disconnecting probe leads.
●Use only insulated voltage probes, test leads and adapters.
●Make sure that the input leads fulfill the safety requirements for your measure-
ment.
The delivered input leads might have a jacket wear indicator that indicates a
worn jacket by different jacket color. In this case, do not use the input lead.
Replace it with a new one.
●Do not use 4 mm banana plugs without protection against contact.
Working with current probes
When working with current probes, you can measure high-frequency currents or
currents that contain high-frequency components.
●Switch off the test circuit while connecting the probe.
●Do not attach the clamp to bare unisolated conductors. To avoid injury from a
short circuit, measure at a location on an insulated wire where the insulation is
sufficient for the circuit voltage.

●Connect the probe only to the secondary side of a breaker. With this measure,
you avoid injury, if a short circuit occurs.
●The following effects can cause burns and fire or damage to the measurement
site:
– Eddy current loss can cause heating of the sensor head.
– Dielectric heating can cause heating of cord insulation and other materials.
Measurement categories
IEC 61010-2-030 defines measurement categories that rate instruments on their
ability to resist short transient overvoltages that occur in addition to the working
voltage. Use the measurement setup only in electrical environments for which
they are rated.
●0 - Instruments without rated measurement category
For measurements performed on circuits not directly connected to mains, for
example, electronics, circuits powered by batteries, and specially protected
secondary circuits. This measurement category is also known as CAT I.
●CAT II:
For measurements performed on circuits directly connected to the low-voltage
installation by a standard socket outlet, for example, household appliances
and portable tools.
●CAT III:
For measurements performed in the building installation, such as junction
boxes, circuit breakers, distribution boards, and equipment with permanent
connection to the fixed installation.
●CAT IV:
For measurements performed at the source of the low-voltage installation,
such as electricity meters and primary overcurrent protection devices.
