OZONE ANALYZER BMT 965 Manual, Rev. 01/2024
___________________________________________________________________________
52
Note: Setting the Auto Zero Interval to zero hours also means, that the analyser does not go
through the purge cycle and does not activate the Purge Unit! In this case, the user shall never
initiate zeroing with ozone applied to the inlet of the Cabinet.
Factory default is an Auto Zero Interval of 24 hours.
Maintenance
The only maintenance recommended is checking the sample gas filter inserts on a regular basis.
Both inserts, the pre-filter insert and the main filter insert, are of pure-white material which easily
shows most kinds of dirt – except if the dirt is white.
Warning: Before opening the sample gas filter make sure that the sample line does not contain
ozone gas, and is not under an overpressure.
Under normal circumstances the replacement
of the filter inserts will be limited to the ex-
change of the pre-filter insert, as this holds
back most particles. While the filter holder is
already open, the main filter insert must be in-
spected, and the decision for replacement
should be based on the contamination found.
Spare pre-filter inserts are provided inside of
the cabinet. Replacement for the main filter
insert is available on request.
The interval of filter insert inspection and re-
placement has to be evaluated by the user.
This interval depends on the degree of dirti-
ness of the ozone sample gas.
Clean the filter holder and O-ring before re-assembling the filter holder thoroughly, in order to
prevent any ozone leaks.
The picture shows the contents of the sample gas filter.
