4. Maintenance and Storage
Follow all maintenance and storage procedures in this section. Incorrect or unapproved maintenance and/or storage
can cause handheld, 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 handheld, 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.
Wipe the keypad, screen, and case with a cloth dampened with a mild
solution of clean water and dish soap (Figure 61). Optimal storage
temperature of the handheld instrument is 0-45°C. The battery pack
permanently loses capacity at a faster rate when above 45°C.
Short-term Storage:
Assure that the handheld instrument is powered off, and store it in a
temperature-controlled, secure location. Ideally all ports should be covered
to prevent dust, water, or other contamination.
Long-term Storage:
In addition ot the short-term storage guidelines above, remove the battery
pack to prevent any damage from possible battery leaks. Reinstall the
battery cover. Store the battery pack in a dry place ideally around 25°C.
