Risk of fatal injury
● Make sure that the waveform measuring equipment connected to this
device's output terminal (BNC) is equipped with a protective earthing with
double-insulation construction.
● If the waveform measuring instrument being connected to the output ter-
minal (BNC) on this device is equipped with any other measurement ter-
minals, take the following precautions to ensure that the other instrument
does not form a bridge between the probe and any hazardous live of a
part.
– Isolate the terminal to which the probe is connected from other termi-
nals on the measuring instrument using basic insulation conforming to
the measurement category, working voltage, and pollution degree
requirements of the circuit being tested.
– If basic insulation requirements cannot be met between the terminal to
which this device is connected and other terminals of the measuring
instrument, make sure that the voltage input to the measurement ter-
minal does not exceed the Separated Extra-Low Voltage Earthed
(SELV-E).
– Read and observe all warnings and precautions relating to electrical
safety for the measuring instrument being connected to the probe.
● Refer to the following standards:
– IEC 61010-1
– IEC 61010-031
– IEC 61010-2-032
● Be sure to observe all operating precautions for the waveform monitoring
instrument (oscilloscope or recorder) and other measurement instruments
to which this device is connected.
● When using a measurement instrument that does not provide isolation
between its input terminals and chassis or other input terminals, please
pay attention to the following points. If a signal is applied to an input ter-
minal other than that to which this device is connected, do not connect the
ground-side terminal to any nonground potential. Otherwise, short-circuit
current will flow through the R&S RT-ZA13 probe power supply, or this
device from the ground terminal, which could cause an electrical accident
or damage.
