4. Maintenance and Storage
Follow all maintenance and storage procedures in this section. Incorrect or unapproved maintenance and/or storage can cause
sensor or cable damage not covered by the warranty.
Storage terms are defined as follows:
Short-term Storage = Less than 4 weeks
Short-term storage is appropriate when the cables, and sensors will be used at regular intervals (daily, weekly, etc.).
Long-term Storage = More than 4 weeks
During long periods of inactivity, such as the “off-season” for environmental monitoring, the instrument, sensors, and cables should
be placed in long-term storage.
YSI recommends cleaning and maintenance before long-term storage.
The conductivity channels should be cleaned after each use. Dip the sensor’s
cleaning brush (included with the maintenance kit) in clean water, insert the brush
at the top of the channels, and sweep the channels 15 to 20 times (
Figure 4
).
If deposits have formed on the electrodes, use a mild solution of dish soap and
water to brush the channels. For heavy deposits, soak the sensor in white vinegar,
then scrub with the cleaning brush. Rinse the channels with clean water following
the sweepings or soak.
The ODO/CT probe must be stored in a moist environment.
