6.3 Installing desiccant - RBRquartz BPR|zero
The logger has a dedicated location for placement of desiccant in the battery end cap, which will accommodate twelve
(12) desiccant capsules (part #
0005669 (qty50) ).
Steps
Remove the battery end cap from the logger - see Opening and closing the RBRquartz BPR|zero .
Inside the battery end cap, there are 12 recessed sockets. Insert a desiccant capsule into each socket,
ensuring that each is securely placed.
3. Replace battery end cap.
*Note these desiccant capsules can be opened, the desiccant removed and replaced or dried.
6.4 Maintenance and repairs
6.4.1 O-rings - RBRquartz BPR|zero
The single most important item of maintenance on any RBR submersible data logger is the care of the O-rings. Any kind
of water leak can damage the circuitry beyond repair and cause complete data loss. Every logger's seal depends upon
its O-rings, not the end cap tightness. Therefore, proper O-ring maintenance is crucial.
O-rings may lose elasticity over time due to pressure, even when the logger is not deployed. We strongly
suggest that the O-rings be replaced regularly, for example, before every deployment, or after a change of
batteries, or at least once a year.
