IMPORTANT SAFETY WARNING
As specified in the italian law Art. 345 of DPR 547 issued on 27.04.1955 when measurements are made
on circuits carrying hazardous supply voltage, using an insulated probe where a metallic part is
accessible, is not allowed.
It is possible to use an insulated alligator clip instead, in this case the high voltage circuit must be
protected by means of a low voltage safety interlock circuit, capable to cut off high voltage before any
alligator clip or probe operation.
The user must install safety protection with a low voltage interlock circuit before any use of PMM SHC-1
or PMM SHC-2 passive probes on hazardous voltage circuit.
The NARDA assumes no liability for the customer’s failure to comply with these requirements.

1.1 Documentation
Enclosed with this manual are a service questionnaire to send back to
NARDA in case that equipment service is needed, and an accessories
check list to verify all accessories enclosed in the packaging, as well as a
calibration certificate.
1.2 Introduction to
Passive Probes
When LISN (Line Impedance Stabilization Network) are not applicable to
EMI conducted test because the current flowing is too high, the conducted
interferences are measured by means of a high impedance voltage probe,
according to C.I.S.P.R 16-1 subclause 12.2.
The passive probes are designed to comply with C.I.S.P.R. 16-1 regulation
and thus include a blocking capacitor to decouple the measured signal
from any AC supply voltage which may be present on the line under test,
they have a total internal resistance between line and earth of more than
1500 ohm.
Designed according to criteria of cheaply and compactness they can be
used together with PMM 7000, PMM 8000 Plus and PMM 9000 Systems
for Conducted Interferences measurement, or any other RF receiver.
The following figure shows the CISPR equivalent circuit.

3 - Preparation for use
3.1 Introduction
This section provides the information needed to install the passive probes.
Included is information pertinent to initial inspection, power requirements,
interconnections, environment, instrument mounting, cleaning, storage and
shipment.
3.2 Packing Unpacking
Inspect the shipping container for damage.
If the shipping container or cushion material is damaged, it should be kept
until the contents of the shipment have been checked for completeness
and the instrument has been checked mechanically and electrically.
Verify the accessories availability in the shipping container referring to the
accessories check list enclosed with the Operating Manual.
Notify any damage to the carrier as well as the NARDA Representative.
3.3 Initial inspection
Inspect the probe for damage before use.
To avoid hazardous electrical shock, do not use the passive probe
when there are signs of shipping damage to any portion of it.
3.4 Preparation for use
The BNC plug of the passive probe must be connected to the RF input
socket of the EMI test receiver.
To avoid any damage caused by transient current pulses, it is
advisable to use a pulse limiter between the passive probe and the
RF input of the EMI test receiver.
Depending on the measurement to be performed, the passive probe can
be used either with the test probe tip or the alligator clip provided as
accessories.
For connections where is difficult to hang the alligator clip to the circuit, the
test probe tip provided can be used, plugging it on the passive probe.
When measurements are made on circuits carrying hazardous AC
supply voltage the alligator clip provided can be used, taking care to
connect the alligator clip and the passive probe before energizing the
circuit under test.
The attenuation of the probes must be taken into account during
measurement, the level indicated on the receiver must be increased
of 30 or 35 dB corresponding to the attenuation of the probe used.
Document SHCEN-90407 - © NARDA 2007
Preparation for use
3-1
Input RF ground connection of the passive probe is very important for
interfering voltage measurement in the range 9 kHz to 30 MHz, it should be
less than λ/100.
A rather short ground connection is always desirable to avoid picking
up other interferences.
The passive probes ground connection is 15 cm long.
For measurements where the RF ground requires a longer ground lead the
total length must be less than or equal to one tenth of the wavelength of
the frequency to be measured.
Before connecting passive probe to the associated test instrument,
ensure that an uninterruptible safety earth ground is provided from
the main power source to the EMI test receiver protective earth
connection.
To avoid hazardous electrical shock, the passive probe must be
connected to the supply mains under test only before energizing any
circuit.
To avoid hazardous electrical shock, prior to energizing either unit
and prior passive probe connection, verify that a common ground
exists between EMI test receiver and ground to be connected to the
passive probe RF input ground.
To avoid hazardous electrical shock, take care to ground the passive
probe RF input ground to the AC supply earth or, if this cannot be
done, to ground the probe permanently to the protective earth ground
conductor.
Any interruption or loosening of the protective earth ground
conductor, either inside or outside the units or in an extension cable
will cause a potential shock hazard that could result in personal
injury.
Verify the safety earth ground functionality before operation.
3.5 Equipment cleaning
Use a clean, dry non abrasive cloth for external cleaning of the probe.
To clean the equipment do not use any solvent, thinner, turpentine,
acid, acetone or similar matter to avoid damage to external plastic
and surfaces.
