4.6 Cleaning the instrument
Clean the instrument after each extended deployment to remove deposits that may have accumulated.

Type
Procedure
Notes
General/biofouling
To clean the exterior, soak in a mild
detergent, then scrub the instrument with
a soft brush.
Avoid scratching the plastic (scratches
make future cleaning more difficult).
Sensor antifouling mesh
Scrub the antifouling mesh with a soft
brush. Replace the antifouling mesh if
needed.
See instructions on removing the
antifouling mesh for more information.
Calcification
Soak in vinegar for six hours, then scrub
the surface using a soft brush.
Soaking in vinegar for more than 24 hours
may damage the O-ring and increase the
chances of a leak.
4.7 Calibrating the instrument
Factory calibration coefficients are calculated for each sensor, and the coefficients are stored on the instrument.
RBR calibration certificates contain calibration equations, coefficients, and residuals for each sensor. Hard copies are
provided with each shipment. RBR can replace lost or misplaced calibration certificates upon request.
RBR recommends calibrating your instrument before any critical deployment, periodically once a year, or if you suspect
the readings to be out of specifications.
Discuss your calibration requirements with RBR. In some cases, the instrument will need to be returned to RBR to have
it checked and re-calibrated.
