Note that all
sensors described below will not be present in all systems
. Please refer to the appropriate user manual
for additional maintenance requirements.
11.1
Sea-Bird Scientific STOR-X Maintenance
As stated in the manual, the STOR-X requires little maintenance. A summary is provided below. Please
refer to the STOR-X user manual for further information.
Preventative Maintenance:
•
Avoid dropping or other hard impacts
•
Rinse with fresh water after each use
•
Store with dummy connectors in place
•
Lightly lubricate male connector pins with Dow Corning DC-111 lubricant or equivalent
•
Any debris (sand, mud) in the female contact sockets should be removed with fresh water to prevent
damage to the contact and o-ring
•
Do not disconnect cables by pulling on the cables. Pull straight back on the connector.
•
Do not put angular loads on the connector
•
Remove external power sources during storage.
Regular Maintenance:
•
Periodically check real time clock accuracy. Plan to replace the internal clock battery after a few years
(up to 5)

Avoid allowing the probe tip to dry out once deployed. A residual film may be left on the optics which
will interfere with measurement accuracy, and may be difficult to clean.
Regular Maintenance:
•
If you are using the copper mesh biofoul guard assembly (ISUS/ISUS-X only):
➢
Depending on the operating environment, the copper biofoul guard assembly may need frequent
cleaning and replacing of the Nitex cloth. Sediment can become trapped in the guard and impede
sample flushing
–
please refer to the sampling tips document (RD4). A spare assembly can be
purchased to allow easy swap out of the guard in the field, allowing a thorough cleaning of the
guard back in the lab. Expect to clean and change the biofoul guard every couple of weeks in a
