Note
• Default settings in the parameter tables are indicated with an asterisk (*) unless explicitly
stated.
• Four sets of parameters allow you to monitor the Device/Sensor Lifetimes and set up
Maintenance/Service schedules, based on operating hours instead of a calendar-based
schedule. See also Remaining Device Lifetime (4.2.), Service Schedule (4.4.), and
Calibration Schedule (4.5.).
• Performing a reset to Factory Defaults will reset all the Maintenance Schedule parameters
to their factory defaults.
• The device operates in years. To view Remaining Sensor Lifetime parameters in hours (via
AMS Device Manager only) see Remaining Sensor Lifetime in Maintenance & Diagnostics
(LTB) (Page 85).
The device monitors the predicted lifetime of the sensor (the components exposed to the
vessel environment). You can modify the expected sensor lifetime, set up schedules for
maintenance reminders, and acknowledge them.
To access these parameters via AMS Device Manager see Remaining Sensor Lifetime in
Maintenance & Diagnostics (LTB) (Page 85).
Lifetime (expected) (4.3.1.)
Allows you to override the factory default.
