1 For Your Safety
To prevent electric shock, personal injury, or fire caused by high voltages, carefully
read and observe the following safety information:
●
This chapter, the first part of the safety booklet, provides warnings and safety infor-
mation for usage of oscilloscopes, probes, and other measurement accessories.
●
The second part of the safety booklet provides basic safety instructions
●
Product manuals provide specific safety instructions for procedures and measure-
ment accessories.
Electrical safety
●
Voltages higher than 30 V RMS, or 42 V peak, or 60 V DC are regarded as hazard-
ous contact voltages. When working with hazardous contact voltages, use protec-
tive 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 electri-
cal 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 cat-
egory (CAT) of your measurement task. If you use other than Rohde & Schwarz
accessories, make sure that they are suitable for the instrument and the measure-
ment 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 mea-
surement setup. Limits and ratings are marked on the products and listed in the
data sheets.
For probes, consider that the rated voltage depends on the frequency. The voltage
limitation curves are provided in the data sheet. Do not exceed these two ratings:
– Maximum measurement voltage from the probe tip to the probe reference lead.
– Maximum floating voltage from the probe reference lead to earth ground.
●
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.
●
Set up all connections to the instrument before applying power.
●
Do not open the instrument casing.
●
Do not use the instrument if the instrument casing, the display or any probe or
accessory are damaged. If you detect or suspect any damage, have the instrument
or accessory inspected by qualified service personnel.
●
Do not operate the instrument in wet, damp or explosive atmospheres. Make sure
that all connectors are completely dry before connecting the inputs.
●
Observe the operating conditions specified in the data sheet and in the basic safety
instructions.
