4.17. Calibration Interval (CALIB. INTERVAL)

set schedules for Maintenance Alerts, and acknowledge them.
To access these parameters via SIMATIC PDM:
• Open the menu Device – Maintenance and select the Calibration Interval tab.
• After modifying values/units as required, click on Write to accept the change,
and Read to view the effect of the change.
Notes:
• 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, Service Interval,
and Calibration Interval.
• The device operates in years. To view Remaining Sensor Lifetime parameters in
hours or days (via SIMATIC PDM only) see Total Expected Sensor Life.
