Cleaning and Storage
Cleaning the Instrument
Clean the instrument body with water and a soft brush or plastic scouring pad, or soak
overnight in a mild acidic solution, such as household vinegar. NEVER submerge the
connector portion of the instrument when it is not connected to a cable.
If the ports near the pressure sensor are clogged with silt or mud, try the following
procedures.
l
Agitate the instrument vigorously in a bucket of clean water.
l
Apply a gentle rinse of water from a wash bottle.
l
In severe cases, remove the nose cone and clean out the holes with a soft brush
or pipe cleaner.
Do not attempt to remove material from the instrument by tapping the instrument against
a surface. To avoid damage to the pressure sensor diaphragm, do not insert any object
into the sensor opening or attempt to dig out dirt or other materials. You void the
instrument's warranty by inserting anything into the sensor opening. If
contamination cannot be removed using the recommendations above, please contact
In-Situ Inc. for cleaning.
A TROLL pressure sensor with the nose cone removed. Do not insert ANY object into
the sensor opening. Doing so voids the warranty.
Twist-Lock Connectors
Keep the pins on all connectors free of dirt and moisture by using the soft protective
dust caps when cable is not attached.
Storage
Store the instrument in a clean, dry place. Place the protective red dust cap on the
cable end or store with cable attached to protect the connector pins and O-ring. Ensure
desiccant is the appropriate size and change it when needed. Store the instrument
where it will not roll off a bench onto a hard surface or sustain other mechanical shock.
Protect the instrument from temperature extremes. Store instruments properly:
