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.

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:
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 inuences
Inthe vicinityofstrongmagneticor/andelectriceldseven
a carefulmeasuring set-upmay notbe suf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specicationsmayoccur
under such conditions.
