5 MAINTENANCE AND RECALIBRATION
The quartz dome should be cleaned regularly. You
may use a mild window cleansing agent which must be
generously rinsed with clear water and wiped dry with a
clean cloth.
The quartz dome can be replaced when damaged. In
order to replace the dome, loosen the 6 screws in the
outer ring and remove the ring and dome. Take care
not to touch the white diffuser. Clean the surface of the
housing and check the condition of the O-ring and re-
place it when necessary. Re-assemble using the new
dome and mounting ring in the reverse order.
Another periodic check is to ensure that the instrument
is level and that the silica gel is still coloured orange.
When the orange silica gel in the drying cartridge is
turned completely transparent (normally after several
months), it must be replaced by fresh silica gel as
supplied in the small refill packs. The contents of one
pack is sufficient for one complete refill.
Periodic recalibration of the sensors is recommended
and provided by Kipp & Zonen. We recommend a
recalibration interval of 12 months.
