DECLARATION OF CONFORMITY
HAMEG Instruments GmbH
Industriestraße 6 · D-63533 Mainhausen
The HAMEG Instruments GmbH herewith declares
conformity of the product:
Product name:
Power Meter
Type:
HM8115-2
with:
HO820
Option:
HO880
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 61000-4-2: 12/2009
EN 61000-4-3: 04/2011
EN 61000-4-4: 04/2013
EN 61000-4-5: 03/2015
EN 61000-4-6: 08/2014
EN 61000-4-11: 02/2005
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 suscep-
tibility the limits for industrial environments will be applied.
All connecting cables will influence emissions as well as sus-
ceptability 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:
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.
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.
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 HAMEG instruments, however,
small deviations from the guaranteed specifications may occur
under such conditions.
