3. EC Declaration of Conformity
This is to certify that TPI 360 series thermometers con-
form to the protection requirements of the council direc-
tive 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
EN 61010-1 1993 Safety Standard
EN 61010-2-031 1995 Safety Standard
EN 61010-2-032 1995 Safety Standard
To ensure conformity with these standard, this instru-
ment must be operated in accordance with the instruc-
tions and specifications given in this manual.
CAUTION: Even though this instrument complies with
the immunity standards, it’s accuracy can be affected
by strong radio emissions not covered in the above
standards. Sources such as hand-held radio trans-
ceivers, radio and TV transmitters, vehicle radios and
cellular phones generate electromagnetic radiation
that could be induced into the test leads of this instru-
ment. Care should be taken to avoid such situations or
alternatively, check to make sure that the instrument is
not being influence by these emissions.
CAUTION: Please follow manufacturers test proce-
dures whenever possible. Do not attempt to measure
unknown voltages or components until a complete
understanding of the circuit is obtained.
