Preparing for deployment
Fitting the Seapoint Fluorometer into the
instrument clamp
Insert the Seapoint Fluorometer into the clamp so that the Hydro-Wiper brush swings
across the optical window of the Seapoint Fluorometer. The brush arm can be manually
moved to check the Seapoint Fluorometer is correctly positioned.
Ensure the Hydro-Wiper
is switched off when manually rotating the wiper brush.
Reposition the Seapoint
Fluorometer if necessary. Tighten the clamp set screw to secure the Seapoint Fluorometer
into the clamp.
Adjusting wiper brush pressure
The brush is mounted on an adjustable arm. The length of the arm controls the brush
pressure applied to the face of the Seapoint Fluorometer. This has been factory set and
should not need adjustment.
The success of the Hydro-Wiper is based on the brush
sweeping lightly
across the optical
window at regular intervals – it is not a scrubbing action. If there is excessive pressure, the
life of the brush will be reduced and damage to the optical surface of the Seapoint
Fluorometer may occur. If the brush pressure is insufficient, contact between the brush
and optical window will be lost in the centre of the window and fouling may occur.
If it is necessary to adjust the brush pressure, loosen the lock nut at the end of the wiper
arm and rotate the wiper arm in the desired direction. Tighten the lock nut after
adjustment.
Mounting the wiper body
Use the brackets located on the back of the wiper body to attach it to the desired
mounting structure.
