ment such as household appliances and similar loads. Be aware that electrically pow-
ered products have risks, such as electric shock, fire, personal 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 indicated
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-spe-
cific safety requirements. Only insert the plug into an outlet with protective conduc-
tor terminal.
●
If a product has an exchangeable fuse, its type and characteristics are indicated
next to the fuse holder. Before changing the fuse, switch off the instrument and dis-
connect it from the power source. How to change the fuse is described in the prod-
uct documentation.
●
Only use intact cables and route them carefully so that they cannot be damaged.
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 deliv-
ered with the product or that is recommended in the product documentation 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.
Performing measurements
Take the following measures for your safety:
●
To ascertain voltage-free state, use an appropriate voltage tester. Any measure-
ment 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. 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 limitation
curves or values are provided in the data sheet. Do not exceed the maximum mea-
surement voltage from the probe tip to the probe reference lead.
●
Never cause any short circuits when measuring sources with high output currents.
●
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 accessories,
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 voltage level,
and you might misjudge the actual risk.
