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.)
,
Remaining Sensor Lifetime (4.3.)
,
and
Service Schedule (4.4.)
.
•
Performing a reset to
Factory Defaults
will reset all the Maintenance Schedule
parameters to their factory defaults.
•
The device operates in years. To view Calibration Interval parameters in hours (via AMS
Device Manager only) see
Calibration Schedule
under Maintenance & Diagnostics
(RESOURCE) (Page 102).
The device tracks calibration intervals based on operating hours and monitors the predicted
lifetime to the next calibration. You can modify the Total Calibration Interval, set schedules for
maintenance reminders, and acknowledge them.
To access these parameters via AMS Device Manager see
Calibration Schedule
under
Maintenance & Diagnostics (RESOURCE) (Page 102).
Calibration Interval (4.5.1.)
User-configurable recommended time between product calibrations.
