6.6 Maintenance and repairs
6.6.1 Instrument calibration
We recommend that you verify the calibration of your data logger before any critical deployment, periodically once a
year, or if you suspect the calibration to be out of specifications. Discuss your calibration needs with RBR. In some
cases, you will be recommended to return the instrument to RBR to have it checked and re-calibrated. Please contact us
for our current calibration fees.
6.6.2 O-rings
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.
Inspecting O-rings
Pay attention to the following areas:
The surface of the O-ring itself
The mating surface on the inside of the case between the threads and the open end
The inner surfaces of the groove in the end-cap where the O-ring sits
Any dirt present should be removed by wiping thoroughly with a soft, lint-free cloth. When cleaning, never use any
material or tool which could scratch the O-ring or any of its mating surfaces. If any dirt is present in the O-ring groove,
then the O-ring should be removed as described below to allow thorough cleaning of the groove. If an O-ring needs to
be removed for any reason, it should be replaced.
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.
