4.8 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 all readings are as expected.  (A level of disturbance in the readings 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. 
 
N.B.  Maximum cable lengths must be less than 3 metres. 
 

At the time of writing this manual (November 2005)  Kane International Ltd is not aware of 
any field based situation where such interference has ever occurred and this advice is only 
given to satisfy the requirements of the Directive.
