1 Notes on Safety
Thank you for purchasing the R&S RT-ZC20 current probe.
To obtain maximum performance from the device, please read this manual first,
and keep it handy for future reference.
Risk of physical injury
This device is designed to comply with IEC 61010 Safety Standards, and
has been thoroughly tested for safety before shipment. However, mishandling during use could result in injury or death, and damage to the device.
Be certain that you understand the instructions and precautions in the manual before use.
Follow these precautions to ensure safe operation and to obtain the full benefits
of the various functions.

R&S®RT-ZC20
Risk of fatal injury
●
To avoid electric shock and short circuits, never attach the clamp to
bare, unisolated conductors.
Make sure to measure at a location on an insulated wire where the insulation is sufficient for the circuit voltage.
●
Be careful to avoid damaging the insulation surface while taking measurements.
●
Refer to the derating characteristics when measuring current that
includes a high-frequency component and never measure any current
that exceeds the rated current. Use with high frequencies or strong
magnetic fields may cause the device to become abnormally hot, resulting in fire, equipment damage, or burns.
Notes on Safety
●
To prevent fire or damage of the measurement target and device as well
as burns, exercise caution concerning the following when measuring
high-frequency currents or currents that contain high-frequency components:
– Eddy current loss may cause heating of the sensor head.
– Dielectric heating may cause heating of cord insulation and other
materials.
●
Be sure to observe all operating precautions for the oscilloscope and
other instruments to which this device is connected.

R&S®RT-ZC20
Risk of fatal injury
●
This device is made for use with the R&S RT-ZA13 probe power supply.
●
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 terminal other than that to which this device is connected, do not connect
the ground-side terminal to any nonground potential. Otherwise, shortcircuit current flows through the R&S RT-ZA13 probe power supply, or
this device from the ground terminal, which could cause an electrical
accident or damage.
Notes on Safety
Shock hazard
Do not allow the device to get wet, and do not take measurements with wet
hands. This may cause an electric shock.
To avoid electric shock when measuring live lines, wear appropriate protective gear, such as insulated rubber gloves, boots, and a safety helmet.

R&S®RT-ZC20
Risk of instrument damage
●
To avoid damage to the device, protect it from vibration or shock during
transport and handling, and be especially careful to avoid dropping.
●
This device should be installed and operated indoors only, between 0°C
and 40°C (32°F to 104°F) and 80% RH or less.
●
Do not store or use the device where it could be exposed to direct sunlight, high temperature, humidity, or condensation. Under such conditions, the device may be damaged and insulation may deteriorate so
that it no longer meets its specifications.
●
Before using the device the first time, verify that it operates normally to
ensure that no damage occurred during storage or shipping. If you find
any damage, contact your dealer or R&S representative.
Notes on Safety
●
This device is not designed to be entirely water- or dust-proof. To avoid
damage, do not use it in a wet or dusty environment.
●
The sensor head is a precision assembly including a molded component, a ferrite core, and a Hall effect element. It may be damaged if subjected to sudden changes in ambient temperature, or mechanical strain
or shock, and therefore great care should be exercised in handling it.
●
Do not apply a static electricity or other source of high voltage to the
sensor. Doing so may damage the internal Hall elements and circuitry of
the sensor.
●
The mating surfaces of the sensor head are precision, and should be
treated with care. If these surfaces are scratched, performance may be
impaired.
●
Measurements are degraded by dirt on the mating surfaces of the sensor head, so keep the surfaces clean by gently wiping with a soft cloth.
●
When the power is on, keep the core section of the sensor closed,
except when clamping it onto the conductor to be measured. The mating
surface of the core section can be scratched while it is open.
●
Keep the clamp jaws and core slits free from foreign objects, which
could interfere with clamping action.
●
Keep the sensor head closed when not in use, to avoid accumulating
dust or dirt on the mating core surfaces, which could interfere with
clamp performance.
