Isolate from all
other metal
To reduce the corrosion of the aluminum parts a zinc anode
is attached to the Connector endcap. This anode must be
exposed to the water for it to be effective.
When mounting the instrument be sure to electrically
isolate the instrument from all other metal. Any contact
with other metal can greatly increase the rate of corrosion.
Isolate the instrument with rubber or plastic to keep the
LISST-100X from being the sacrificial anode for the
mounting hardware. Failure to properly isolate the
instrument from all other metal will void the warranty.
A set of stainless steel clamps with rubberized interiors
ships as part of the instrument package. Use these or the
plastic clamps for mounting, and make sure that no metal is
in direct contact with the pressure housing or other
components of the instrument. If you lose the spare
clamps, replacement clamps are available for purchase
from Sequoia. See Appendix I: LISST Accessories on
page 126.
Storage notes Again it must be emphasized that the LISST-100X is a
sensitive instrument. When not in use, the instrument
should be stored in its shipping case. For longer storage
(year or so), the communication cable should be
disconnected and the battery pack should be removed. If
you do not wish to remove the battery or disconnect it,
battery life can be prolonged with the use of the Low Power
Sleep Mode. In this mode the instrument will use no more
than 10% of a typical battery life over a 6 month duration.
Low Power
Sleep Mode
To put the instrument into low power sleep mode choose
Put LISST to Sleep from the LISST menu or click the
button.
NOTE: To get the lowest power consumption the
Communications cable must be disconnected from the
instrument and the Switch Lever on the endcap must be in
the “1” position.
Cleaning the
optical windows As has been noted earlier, the condition of the windows is
critical to the performance of the LISST-100X. Care must
be taken when cleaning the windows. The windows and
the instrument should be rinsed thoroughly with fresh water
after each deployment. The windows should be cleaned
with a soft cloth or lens tissue. Liquid detergent/soap and
water may be used. For removing grease spots, finger
prints, etc, alcohol may be used. Do not use stronger
solvents such as Acetone or Toluene.
