General information regarding the CE marking
HAMEG instruments fulfill 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 influence 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.)
sufficiently 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 long. 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 long.
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. Influence on measuring instruments.
Under the presence of strong high frequency electric or magnetic fields, even with careful setup of the measuring
equipment an influence 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 specifications may result from such conditions in individual cases.
