SAFETY NOTES

Read carefully before using the product

MPB works to provide its customers with the best safety conditions available,
complying with the current safety standards. The instrumentation described in
this manual has been produced and tested in conditions that fully comply with
the European standards. To maintain it in safe conditions, ensure the correct use
of the product and prevent any danger, these general instructions must be fully
understood and applied before any use.

This product is intended for industrial environments and laboratories and
should be used by authorized personnel only. The CCM was designed and devel-
oped to be used according to the norms and regulations of the country where the
worker is operating in.

Please use the device only after checking the presence and valid-
ity of the safety devices (e.g. breakers, dierential switches and the
conformity of the grounding)

MPB disclaims any responsibility for a dierent use of the device.

For safety reasons, the

GROUND PLANE

mode measurement (whose expla-

nation will be detailed in the following chapters) MUST always be done

before

the

HAND

mode measurement. The

GROUND PLANE

mode measurement
shall not exceed the limits dened by the 2013/35/EU regulation (CCM-A ver-
sion) or 2004/40/EC (for the CCM version) and must be performed ONLY with
the cover provided with the instrument. Please also note that even when in

GROUND PLANE

mode, total safety is not guaranteed if the use of the instru-
ment is not made according to the instructions explained in this manual. All
these procedures will be better underlined below.

1. General Information

1.1 Introduction

CCM was designed to measure in a fast and accurate way the contact current
that may be generated when touching electrical/electronic equipment inside a
radio frequency eld.

1.2 Description

CCM (Figure 1.1) is a portable measuring device with two measurement modes.
It can measure by means of the

GROUND PLANE

(with related cover to wrap
the instrument and resistance for closing the circuit on the ground), and it can
work without a cable, making use of the impedance level of the user through the
conductive area on the handle. In the next chapters we will go more deeply into
this subject.
