EC DECLARATION OF CONFORMITY 1

This is to certify that model 122 conforms to the protection
requirements of the council directive 89/336/EEC, in the
approximation of laws of the member states relating to
Electromagnetic compatibility and 73/23/EEC, The Low
Voltage Directive by application of the following standards:

EN 50081-1 1992 Emissions Standard
EN 50082-1 1992 Immunity Standard
EN61010-1 1993 Safety Standard
EN61010-2-031 1995 Safety Standard

To ensure conformity with these standards, this instrument
must be operated in accordance with the instructions and
specifications given in this manual.

CAUTION:

Even though this instrument complies with the immunity standards, the
accuracy can be affected by strong radio emissions not covered in the above
standards. Sources such as hand held radio transceivers, radio and TV trans­mitters, vehicle radios and cellular phones generate electromagnetic radia­tion that could be induced into the test leads of this instrument. Care should
be taken to avoid such situations or alternatively, check to make sure that the
instrument is not being influenced by these emissions.
