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 infl uence 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 infl uences
In the vicinity of strong magnetic or/and electric fi elds even a careful
measuring set-up may not be suffi cient to guard against the intrusion
of undesired signals. This will not cause destruction or malfunction of
HAMEG instruments, however, small deviations from the guaranteed
specifi cations may occur under such conditions.
