Section 9: Care & Maintenance
Storage
Store the Aqua TROLL Instrument clean and dry. Place the
protective red dust cap on the cable end, or store with cable
attached to protect the connector pins and O-ring.
Store the instrument where it will not fall onto a hard surface.
Protect the instrument from temperature extremes. Store within
a temperature range of -40° C to 65° C (-40° F to 149° F).
General Maintenance
Twist-Lock Connectors
Keep the pins on all connectors free of dirt and moisture by
using the soft protective dust cap when cable is not attached to
an instrument.
Cable Vent Tube (Vented Cable)
Vented cable ensures that atmospheric pressure is the reference
pressure to the vented pressure sensor diaphragm. The vent
tube should not be blocked, kinked, or otherwise obstructed.
Such obstructions will cause barometric pressure to appear in
measurements, and errors will be introduced due to thermal
expansion and contraction of air within the vent tube and probe.
The recommended minimum bend
radius is 13.5 mm (0.54 in), which is
twice the cable diameter.
The minimum
bend radius for
vented cable is
13.5 mm (0.54 in).
Do not sub merge
the cable
connector; do not
immerse in any fluid.
TIP: Be sure to
replace the desiccant
before it appears
pink. Expired desiccant can
allow moisture build up in the
vent tube, causing a blockage
resulting in inaccurate data.
