EC DECLARATION OF CONFORMITY

This is to certify that model 120 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
