IMPORTANT INFORMATION
EC LIMITATIONS OF USE
For EC users only:
Instruments manufactured after 1.1.96 are compliant with the EC EMC Directive
89/336/EEC (amended by 92/31/EEC & 93/68/EEC) and bear the CE mark. To
maintain compliance with this directive, the following should be observed:
• Headphones should not be used with the instrument in the EC.
• Only adequately screened cables should be used with the instrument: Thermo ‘curly’
cables 3190A - 3192A, 3201A & 3203A may not offer adequate screening.
• The instrument should be operated with batteries only in a harsh r.f. environment. In
other environments, only Thermo Electron approved DC Adaptors should be used in
place of batteries. These Adaptors include a ferrite tube close to the +5 V connector.
• CE marked Selectra instruments should only be used when connected to Intelligent
Probes having adequately screened cables, Thermo Type 3212, less than 3 metres in
length. Connecting probes which have integral cable may render the Selectra non
EMC compliant.
• The AP6A, BP17A and DP8A probes should be of modified design before they are
used with CE marked Delta5 instruments. The modification is identifiable on the
serial number label as MOD. record 1.
• Maintenance:
details of necessary actions are given in the maintenance section of this
manual.
For other users:
Where headphones may be used, the headphone socket on CE marked units is of
professional grade; it may not be compatible with plugs found on low-cost personal
stereo headphones. Contact the Service Department if difficulties arise.
