ELECTROMAGNETIC COMPATIBILITY
The European Council Directive 89/336/EEC requires that electronic equipment does
not generate electromagnetic disturbances that exceed defined levels and has an
adequate level of immunity to enable it to be operated as intended. The specific
standards applicable to this product are detailed in the appendices.
Since there are many electrical products in use that pre-date this Directive and may
emit electromagnetic radiation in excess of the standards defined in the Directive
there may be occasions where it would be appropriate to check the analyser prior to
use. The following procedure should be adopted:
•
Go through the normal start up sequence in the location where the equipment is to
be used.
•
Switch on all localised electrical equipment that might be capable of causing
interference.
•
Check that performance is as expected. (A level of disturbance in the
performance is acceptable). If not adjust the position of the instrument to minimise
interference or switch off, if possible, the offending equipment for the duration of
the test.
At the time of writing this manual (December 2006) there is no awareness of any field
based situation where such interference has ever occurred and this advice is only
given to satisfy the requirements of the Directive.
