General information regarding the CE marking

HAMEG instruments fulfi ll the regulations of the EMC directive. The 
conformity test made by HAMEG is based on the actual generic- and 
product standards. In cases where different limit values are applicable, 
HAMEG applies the severer standard. For emission the limits for 
residential, commercial and light industry are applied. Regarding the 
immunity (susceptibility) the limits for industrial environment have 
been used.

The measuring- and data lines of the instrument have much infl uence 
on emmission and immunity and therefore on meeting the acceptance 
limits. For different applications the lines and/or cables used may 
be different. For measurement operation 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. Without a special instruction in the manual for a reduced 
cable length, the maximum cable length of a dataline must be less than 
3 meters and not be used outside buildings. If an interface has several 
connectors only one connector must have a connection to a cable.
Basically interconnections must have a double screening. For IEEE-bus 
purposes the double screened cables HZ72S and HZ72L from HAMEG 
are 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 
and not be used outside buildings.
Signal lines must screened (coaxial cable - RG58/U). A proper ground 
connection is required. In combination with signal generators double 
screened cables (RG223/U, RG214/U) must be used.

3. Infl uence on measuring instruments.
Under the presence of strong high frequency electric or magnetic fi elds, 
even with careful setup of the measuring equipment an infl uence of 
such signals is unavoidable.
This will not cause damage or put the instrument out of operation. Small 
deviations of the measuring value (reading) exceeding the instruments 
specifi cations may result from such conditions in individual cases.
