confIGure InstruMents
Data Manager allows for easy and quick configuration of single or multiple
instruments. once you have uploaded a site list or configuration file, you can edit
it as needed, save it, and download it to other instruments. You no longer need
to configure each instrument individually. By using the same configuration file
for all instruments, you can rest assured that all instruments will have identical
settings.
New site lists and configuration files can be created in Data Manager as well.
these lists and files can be downloaded to one or multiple instruments. Save
time by creating these files on your PC and downloading them to the instrument
as opposed to creating them on the instrument.

this section describes the proper procedures for care, maintenance and storage
of the sensors. the goal is to maximize their lifetime and minimize down-time
associated with improper sensor usage.
updatInG InstruMent fIrMWare
the instrument’s firmware can be updated via www.ysi.com. there you will find
the new firmware file and instructions on how to update the instrument. there
is no need to send the instrument back to the factory for upgrades.
General MaIntenance
GENERAL MAINtENANCE - o-RINGS
the instrument utilizes o-rings as seals to prevent water from entering the battery
compartment and sensor ports. Following the recommended procedures will
help keep your instrument functioning properly.
If the o-rings and sealing surfaces are not maintained properly, it is possible that
water can enter the battery compartment and/or sensor ports of the instrument.
If water enters these areas, it can severely damage the battery terminals or sensor
ports causing loss of battery power, false readings, and corrosion to the sensors
or battery terminals. therefore, when the battery compartment lid is removed,
the o-ring that provides the seal should be carefully inspected for contamination
(e.g. debris, grit, etc.) and cleaned if necessary.
the same inspection should be made of the o-rings associated with the sensor
connectors when they are removed. If no dirt or damage to the o-rings is
evident, then they should be lightly greased without removal from their groove.
However, if there is any indication of damage, the o-ring should be replaced
with an identical o-ring. At the time of o-ring replacement, the entire o-ring
assembly should be cleaned.
To remove the o-rings:
Use a small, flat-bladed screwdriver or similar blunt-tipped tool to remove the
o-ring from its groove. Check the o-ring and the groove for any excess grease or
contamination. If contamination is evident, clean the o-ring and nearby plastic
parts with lens cleaning tissue or equivalent lint-free cloth. Alcohol can be used
to clean the plastic parts, but use only water and mild detergent on the o-ring
itself. Also, inspect the o-rings for nicks and imperfections.
Using alcohol on o-rings may cause a loss of elasticity and may
promote cracking. Do not use a sharp object to remove the
o-rings. Damage to the o-ring or the groove may result.
Before re-installing the o-rings, make sure to use a clean workspace, clean hands,
and avoid contact with anything that may leave fibers on the o-ring or grooves.
Even a very small amount of contamination (hair, grit, etc.) may cause a leak.
To re-install the o-rings:
Place a small amount of o-ring grease between your thumb and index finger.
(More grease is Not BEttER!)
Draw the o-ring through the grease while pressing the fingers together to place
a very light covering of grease to the o-ring. Place the o-ring into its groove
making sure that it does not twist or roll.
Use your grease-coated finger to once again lightly go over the mating surface
of the o-ring.
Do not over-grease the o-rings. The excess grease may collect
grit particles that can compromise the seal. Excess grease
can also cause the waterproofing capabilities of the o-ring
to diminish, potentially causing leaks. If excess grease is
present, remove it using a lens cloth or lint-free cloth.
