Shock hazard caused by high voltages
To avoid electrical shock and personal injury, and to prevent damage to the instrument
or any other products connected to it, observe the following:
●
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 measurement cate-
gory (CAT) of your measurement task.
●
Test leads and measurement accessories used for multimeter measurements on a
live mains circuit must be rated for CAT III or CAT IV according to IEC 61010-031.
The voltage of the measured circuit must not exceed the rated voltage value.
Maximum input voltage:
●
At BNC inputs: CAT IV 300 V
●
With probe R&S RT-ZI10 or R&S RT-ZI11: CAT IV 600 V, CAT III 1000 V
●
Meter input: CAT IV 600 V; CAT III 1000 V
Voltage ratings are V RMS (50 to 60 Hz) for AC sine wave and V DC for DC applica-
tions.
Risk of electrical shock or fire
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 appropriate pro-
tective measures to preclude direct contact with the measurement setup:
●
Use only insulated voltage probes, test leads and adapters.
●
Do not touch voltages higher than 30 V RMS or 42 V peak or 60 V DC.
