7. MAINTENANCE
A Model 6040 Maintenance Kit is available for use with the 6000
UPG
. The kit includes several
items which will be helpful or necessary in performing the proper routine maintenance on the
6000
UPG .
The 6040 Maintenance Kit includes a variety of O-rings, a hex driver, replacement hex cap screws,
2 cleaning brushes, O-ring lubricant, and 2 replacement pressure caps for sealing the sonde cable
connector.
The Model 6040 Maintenance Kit can be ordered from any authorized YSI dealer, or directly from
YSI. See Appendix C for details.
7.1 SONDE MAINTENANCE
When caring for the 6000 UPG sonde, it is important to remember that the sonde is sealed at the
factory, and there is never a need to gain access to the interior circuitry of the sonde; in fact, to do
so would void the manufacturer's warranty.
SONDE AND SENSOR STORAGE
Since the introduction of the YSI Environmental Monitoring Systems (EMS) product line several
years ago, YSI has learned a great deal about storage protocols which will maximize the lifetime of
our sensors. This knowledge has come from our own extensive in-house testing programs as well
as from feedback from a large number of customers and sales representatives. We have now
summarized these storage recommendations in a separate document which is included in this
manual as Appendix G.
These current storage guidelines are, in some cases, slightly different from those provided in our
previous manuals on the YSI Models 6000
UPG , 600, and 600XL. We believe that the previous
storage recommendations were good, but that the procedures described in the current version are
better. No doubt these recommendations will continue to be refined slightly as we introduce new
sensors and gain additional information from testing. Please refer to Appendix G for detailed
instructions for sensor storage. Note that the appendix deals with instruments other than the
6000
UPG , so be sure to refer specifically to the instructions for the instrument which you have
purchased.
Proper storage of the 6000
UPG
sonde between periods of usage will not only extend the life of the
sensors, but will also ensure that the unit will be ready to use as quickly as possible in your next
application
