4.7 Normal Shutdown Sequence
DO THIS EVERY TIME YOU USE THE ANALYSER.
Remove the probe from the flue - TAKE CARE ! THE PROBE WILL BE HOT -
and allow it to cool naturally. Do not immerse the probe in water as this will be drawn
into the analyser and damage the pump and sensors.
Once the probe is removed from the flue, the oxygen reading 20.9% and the CO
reading is zero press and the analyser will switch off.
Check the water trap and probe tubes for water before packing away.
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 (January 1997) 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.
4.9 HC104 Module
With this module fitted and working the CO2 value is always the measured value not
the calculated value. The handset display and print out indicate that the CO2 value is
a measured value by showing CO2m. If the module is not fitted, the KM9106
automatically defaults to calculated CO2. If during start up calibration a fault is
detected in the CO2 module, the instrument will default to calculated. If the
instrument displays CO2m FAULT during operation, by switching OFF and then ON,
the instrument will default to calculated CO2.
