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 connections the double-shielded
HAMEG cables HZ72S and HZ72L are 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 HAMEG instruments, however, small
deviations from the guranteed specifications may occur under such conditions.
