Shock hazards caused by high voltages
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 vol-
tages, use appropriate protection to avoid electrical shock and injuries:
●
Use only insulated probes, cables, test leads and adapters.
●
Do not touch voltages higher than 30 V RMS or 42 V peak or 60 V DC.
●
Do not apply input voltages above the rating of the instrument and the
accessories.
●
Use only probes, test leads, and adapters that comply with the mea-
surement category (CAT) of your measurement task.
●
Test leads and measurement accessories used for multimeter measure-
ments on a live mains circuit must be rated for CAT III or CAT IV accord-
ing to IEC 61010-031. The voltage of the measured circuit must not
exceed the rated voltage value.
BNC connectors
The channel inputs have double channel-to-channel isolation that allows for inde-
pendent floating measurements at each input, see Chapter 2.3, "Input isolation",
on page 18. The maximum input voltage is:
●
CAT IV 300 V
●
With probe R&S RT-ZI10 or R&S RT-ZI11: CAT IV 600 V, CAT III 1000 V
Multimeter inputs
DMM inputs are 4 mm banana plug inputs, which are fully isolated from scope
inputs, interfaces, and ground. The maximum input voltage is CAT IV 600 V;
CAT III 1000 V.
