8.2 HOW TO REPLACE THE ACTIVATED CARBON FILTER
This filter eliminates the dust and unburnt hydrocarbons in the environment from the air
used to autozero the instrument.
When the instrument is used in optimum conditions, this filter should be replaced once a
year.
To replace the filter, just disconnect the tube that holds it in place and, after fitting a new
filter, set it in the right position in the relative clip.
8.3 PERIODICAL INSPECTION OF THE ANALYZER
It is obligatory to have the instrument checked at least once a year and not beyond 12
months from the date of the last inspection.
These operations are official, thus all the procedures described in the Circular must be
complied with.
These periodical inspections may only be carried out by Authorized Laboratories and
must be reported in the "Metrological Book" which must be kept ready to hand with the
instrument.
The program warns the user when the periodical inspection period is due by means of a
mask at the beginning of the OFFICIAL TEST FOR ITALY.
At the end of this period, the instrument can still be used, but the tests could be
annulled if the vehicles are to be type approved.
This is why users are strongly urged to always comply with the required inspections.
These periodical inspections must be carried out by specialized personnel authorized by
the manufacturer.
