DECLARATION OF CONFORMITY

HAMEG Instruments GmbH
Industriestraße 6 · D-63533 Mainhausen
The HAMEG Instruments GmbH herewith declares
conformity of the product:
Product name: Triple Power Supply
Type: HM7042-5
complies with the provisions of the Directive of the
Council of the European Union on the approximation of
the laws of the Member States
z relating to electrical equipment for use within defined
voltage limits (2006/95/EC) [LVD]
z relating to electromagnetic compatibility (2004/108/
EC) [EMCD]
z relating to restriction of the use of hazardous
substances in electrical and electronic equipment
(2011/65/EC) [RoHS].
Conformity with LVD and EMCD is proven by compliance
with the following standards:
EN 61010-1: 04/2015
EN 61326-1: 07/2013
EN 55011: 11/2014

EN 61000-6-3: 11/2012
For the assessment of electromagnetic compatibility, the
limits of radio interference for Class B equipment as well
as the immunity to interference for operation in industry
have been used as a basis.

General remarks regarding the CE marking

HAMEG measuring instruments comply with the EMI norms. Our tests
for conformity are based upon the relevant norms. Whenever different
maximum limits are optional HAMEG will select the most stringent
ones. As regards emissions class 1B limits for small business will be
applied. As regards susceptability the limits for industrial environments
will be applied.
All connecting cables will influence emissions as well as susceptability
considerably. The cables used will differ substantially depending on the
application. During practical operation the following guidelines should
be absolutely observed in order to minimize EMI:
1. Data connections
Measuring instruments may only be connected to external associated
equipment (printers, computers etc.) by using well shielded cables.
Unless shorter lengths are prescribed a maximum length of 3 m must
not be exceeded for all data interconnections (input, output, signals,
control). In case an instrument interface would allow connecting several
cables only one may be connected.
In general, data connections should be made using double-shielded
cables. For IEEE-bus purposes the double screened cable HZ72 from
HAMEG is suitable.
2. Signal connections
In general, all connections between a measuring instrument and the
device under test should be made as short as possible. Unless a shorter
length is prescribed a maximum length of 3 m must not be exceeded,
also, such connections must not leave the premises.
All signal connections must be shielded (e.g. coax such as RG58/U).
With signal generators double-shielded cables are mandatory. It is
especially important to establish good ground connections.
3. External influences
In the vicinity of strong magnetic or/and electric fields even a careful
measuring set-up may not be sufficient to guard against the intrusion
of undesired signals. This will not cause destruction or malfunction of
General remarks regarding the CE marking
HAMEG instruments, however, small deviations from the guaranteed
specifications may occur under such conditions.
