The device tracks calibration intervals based on operating hours and monitors the

schedules for maintenance reminders, and acknowledge them.

• Open the menu Device – Maintenance and select the Calibration Schedule tab.
• After modifying values/units as required, click on Write to accept the change,
and Read to view the effect of the change.
• Click on Calibration Performed to restart the timer and clear any fault
messages.

Notes:
• 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 Service/Calibration schedules, based on operating hours instead of a
calendar-based schedule. See also Remaining Device Lifetime (4.7.), Remaining
Sensor Lifetime (4.8.), and Service Schedule (4.9.).
• 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 or
days (via SIMATIC PDM only) see Calibration Interval (4.10.1.).
