Calibration Schedule (4.5.)
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
Service/Calibration 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 or days
(via SIMATIC PDM only) see Calibration Interval (4.5.1.).
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 SIMATIC PDM:
●
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.
