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.
