(EC conformity marking)
The manufacturer declares the conformity of this product with the actual required safety standards in
accordance with the Low Voltage Directive (LVD) 2006/95/EC:
CEI/IEC 61010-031:2008 Safety requirements for electrical equipment
for measurement, control and laboratory use -
Part 031:
Safety requirements for hand-held probe
assemblies for electrical measurement and test
WEEE/ RoHS Directives
(EC conformity marking)
This electronic product is classified within the WEEE/ RoHS* category list as monitoring and control
equipment (category 9). Category 9 products are exempted from the restrictions under the scope of the
RoHS directive.
Your help and efforts are required to protect and keep clean our environment. Therefore return this
electronic product at the end of its life either to the Service Department of PMK Mess- und
Kommunikationstechnik GmbH or take care of separate WEEE collection and professional WEEE treatment
yourself. Do not dispose as unsorted municipal waste.

IEC Measurement Categories PML111O
Definitions and Examples (Clause 6.5.2)
Measurement Category I Definition: Measurement category I is for measurements performed
on circuits not directly connected to a mains supply.
Examples: Measurements in circuits not derived from a mains supply
and specially protected (internal) circuits derived
from a mains supply. In the latter case, transient stresses
are variable; for that reason it is required that the transient
withstand capability of the equipment is made known to
the user.
Measurement Category II Definition: Measurement category II is for measurements performed
CAT II on circuits directly connected to the low voltage
installation.
Examples: Household appliances, portable tools and similar
equipment.
Measurement Category III Definition: Measurement category III is for measurements
CAT III performed in the building installation.
Examples: Measurements on distribution boards, circuit breakers,
wiring including cables, bus-bars, junction boxes, switches,
socket-outlets in the fixed installation and equipment for
industrial use like for example stationary motors with per-
manent connection to the fixed installation.
Measurement Category IV Definition: Measurement category IV is for measurements
CAT IV performed at the source of the low-voltage installation.
Examples: Electricity meters and measurements on primary over
current protection devices and and ripple control units.
IEC Pollution Degrees
Definitions (Clause 3.5.6 )
Pollution Degree 1 No POLLUTION or only dry, non conductive POLLUTION.
NOTE The POLLUTION has no influence.
Pollution Degree 2 Only- non conductive POLLUTION. Occasionally, however, a temporary
conductivity caused by condensation must be accepted.
Pollution Degree 3 Conductive POLLUTION occurs or dry, non-conductive POLLUTION occurs
which becomes conductive due to condensation which is to be expected.

IEC Safety Symbols PML111O
The following symbols may appear on the product or in this instruction manual:
Caution, risk of danger. Refer to manual.
Caution, risk of electric shock.
Earth (ground) TERMINAL.
Safety Information
To avoid personal injury and to prevent fire or damage to this product or products connected to it, review and
comply with the following safety precautions. Be aware that if you use this probe assembly in a manner not
specified the protection this product provides may be impaired.
Only qualified personnel should use this probe assembly.
Use only grounded instruments.
Do not connect the probe ground lead to a potential other than earth ground. Always make sure the probe and
the measurement instrument are grounded properly.
Connect and disconnect properly.
Connect the probe output to the measurement instrument and connect the ground lead to earth ground before
connecting the probe to the circuit under test. Disconnect the probe input and the probe ground lead from the
circuit under test before disconnecting the probe from the measurement instrument.
Observe probe and probe accessory ratings.
Do not apply any electrical potential to the probe input which exceeds the maximum ratings of the probe or the
accessories connected to it. In a combination always the lower rating / measurement category applies to both
probe and accessories connected to it.
Make sure to comply with the voltage versus frequency derating curve on page 8.
Keep away from live circuits.
Avoid open circuitry. Do not touch connections or components when power is present.
Do not operate with suspected failures.
Refer to qualified service personnel.
Indoor use only.
Do not operate in wet/damp environment. Keep product surfaces dry and clean.
Do not operate the product in an explosive atmosphere.

The accessories provided with the probe have been safety tested. Do not use
any other accessories than those “originally” provided.
Handling
Handle with care especially when fitted with the extra thin and sharp spring contact tip to avoid
any injury. Note that the probe cable is a sensitive part of the probe. Do not damage through
excessive bending or pulling. Avoid mechanical shock to this product in general to guarantee
accurate performance and protection.
Maintenance
Cleaning
To clean the exterior of the probe use a soft cloth moistened with either distillated water or isopropyl alcohol.
Before use allow the probe to dry completely.

Maintenance PML111O
Changing the Probe Tip
To change the probe tip use pliers to grip and pull it carefully straight out of its contact socket, along the
axis of the probe. Do not grip the white plastic insulator or the housing with pliers, because the tip could be
squeezed and cannot be removed and respectively the probe could be damaged.
If the probe tip is removed, the new tip can be inserted with pliers into the contact socket, along the axis
of the probe. In order to insert the probe tip completely into the housing, press the probe tip against a hard
surface carefully.
Use pliers to grip and pull the probe tip carefully out
of its contact socket.
Do not grip the white plastic insulator or the probe
housing with pliers.
About PML Probe Series
The compact design with only 2.5 mm housing diameter at the probe tip is ideal for measurements of SMT
components. It provides a much better visibility over of the DUT (device under test) as conventional 5 mm
probe housing designs.
A true PMK GmbH feature the exchangeable probe tip is also available for the PML series. The gold plated
spring contact or the rigid tip are only 0.5 mm in diameter. The tip replacement is easy and gives the engineer
the best choice.
Particularly for HF measurements on IC´s, a short as possible ground connection is recommendable.
Due to long ground leads most conventional adaptations bring additional inductance and resonances into the
measurement which will result in false or inaccurate readings. The innovative IC contacting system of the PML
with 5 different IC adapters from 0.5 to 1.27 mm pitch in combination with the ground blade and IC ground
copper pad is the ideal solution for short-circuit-safe, reproducible, and authentic measurements.
These great advantages and over 30 accessories parts for the new PML probe series will offer various
configuration to solve most adaptation desires.
IC contacting system with IC adapter,
ground blade and IC ground copper pad.
Accessory shown in this picture could be obtained
from PMK and is not in the scope of delivery.
