Connecting to power
If you connect the product to an external power supply, use the one delivered with
the product or recommended in the product documentation. The external power
supply must conform to the country-specific regulations.
Performing measurements
Take the following measures for your safety:
●
Voltages higher than 30 V RMS, or 42 V peak, or 60 V DC are regarded as
hazardous contact voltages. When working with hazardous contact voltages,
use protective measures to preclude direct contact with the measurement
setup:
– Do not touch exposed connections and components when power is
applied.
– Use only insulated voltage probes, test leads and adapters.
●
Make sure that only personnel familiar with the potential risks of measuring
electrical quantities controls the instrument. Observe applicable local or
national safety regulations and rules for the prevention of accidents.
●
Use only specified probes and accessories that comply with the measurement
category (CAT) of your measurement task. If you use other than
Rohde & Schwarz accessories, make sure that they are suitable for the instru-
ment and the measurement task.
●
Observe all voltage and current ratings of the instrument, the probes, and the
accessories. The lowest rated component defines the rating of the complete
measurement setup. Limits and ratings are marked on the products and listed
in the specifications documents.
For probes, consider that the rated voltage depends on the frequency. The
voltage limitation curves are provided in the specifications document. Do not
exceed these two ratings:
– The maximum measurement voltage from the probe tip to the probe refer-
ence lead.
– The maximum floating voltage from the probe reference lead to the
ground.
●
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.
●
Set up all connections to the instrument before applying power.
●
Do not open the instrument casing.
