BATTERY CHAMBER
When changing batteries, always check the inside of
the battery chamber to assure that no water has seeped
into the chamber. If the chamber has become
wet, dry the chamber thoroughly with
compressed air, a clean cloth, or paper towels.
Dry and clean the battery chamber lid with a clean
cloth. Before reinstalling the lid, place a very thin coat
of O-ring lubricant on the lid O-ring.
NOTE: If you remove the battery lid with the sonde in
a horizontal position, moisture will not be able to run
into the battery compartment.
SONDE PROBE PORTS
Whenever a probe is installed, removed, or replaced, it
is extremely important that the entire sonde and all
probes be thoroughly dried prior to the removal of the
probe or the probe port plug. This will prevent water
from entering the port. Once the probe or plug has
been removed, examine the connector inside the sonde
probe port. If any moisture is present, use compressed
air to completely dry the connector. If the connector is
corroded, return the sonde to your dealer or directly to
YSI's Product Service Department (see Appendix C for
details). When reinstalling a probe or port plug, lightly
grease the O-ring with lubricant supplied in the 6040
Maintenance Kit.
