9 Care & Maintenance
The uvSVX is remarkably robust, being primarily constructed of titanium. The only maintenance
required, other than periodic recalibration as necessary or recommended at maximum of 2 years, is
to keep the instrument and sensors as clean as possible. The instrument should be rinsed with
freshwater when recovered and any debris or growth gently removed.
Do not attempt to remove the acetal Lock Screw Cap from the Pressure Module. If debris is caught
under the cover attempt to remove it under slowly flowing water,
use no tools
. If this fails contact
Valeport for further advice. If the sensor diaphragm is damaged in any way it will have to be
replaced.
The instrument should be stored in its transit case when not in use. It is not necessary to remove
the Interchangeable Pressure Sensor Module during storage.
Any damage to this diaphragm will render the Pressure Module warranty invalid
9.1 Calibration
