General information regarding the
CE marking
HAMEG instruments fulfi ll the regulations of the
EMC directive. The conformity test made by HA-
MEG is based on the actual generic and product
standards. In cases where different limit values
are applicable, HAMEG applies the strictest
standard. For emission the limits for residential,
commercial and light industry are applied. Re-
garding the immunity (susceptibility) the limits
for industrial environment have been used.
The measuring and data lines of the instrument
have much infl uence on emission and immunity
and therefore on meeting the acceptance limits.
For different applications the lines and/or cables
used may be different. For measurement opera-
tion the following hints and conditions regarding
emission and immunity should be observed:
1. Data cables
For the connection between instruments resp.
their interfaces and external devices, (computer,
printer etc.) suffi ciently screened cables must
be used.
Maximum cable length of data lines must not ex-
ceed 3 m. The manual may specify shorter lengths.
If several interface connectors are provided only
one of them may be used at any time.
Basically interconnections must have a double
screening. For IEEE-bus purposes the double
screened cable HZ72 from HAMEG is suitable.
2. Signal cables
Basically test leads for signal interconnection
between test point and instrument should be
as short as possible. Without instruction in the
manual for a shorter length, signal lines must be
less than 3 meters long.
Signal lines must be screened (coaxial cable - RG58/
U). A proper ground connection is required. In com-
bination with signal generators double screened
cables (RG223/U, RG214/U) must be used.
3. Infl uence on measuring instruments.
In the presence of strong high frequency electric
or magnetic fi elds, even with careful setup of the
measuring equipment an infl uence can not be
excluded.
