3.3.6.1. Calibration Interval
User-configurable recommended time between product calibrations.
3.3.6.2. Time Last Calibration
Time elapsed since last calibration. Can be reset to zero after performing a
calibration.
To reset to zero:
• In SIMATIC PDM, open the menu Device – Maintenance, click on the
Calibration Schedule tab, and click on Calibration Performed to re-
start the timer and clear any fault messages.
• Via the local push buttons, navigate to Maintenance and Diagnostics
(3.) > Maintenance (3.3.) > Calibration Schedule (3.3.6.) > Time Last
Calibration (3.3.6.2.), and set to zero.
3.3.6.3. Time Next Calibration
Read only. Calibration Interval (3.3.6.1.) less Time Last Calibration (3.3.6.2.)
3.3.6.4. Reminder Activation
Allows you to enable a maintenance reminder
.
a) First set the values in Reminder 1 before Calibration (Required)
(3.3.6.5.)/Reminder 2 before Calibration (Demanded) (3.3.6.6.).
b) Select the desired Reminder Activation option.
3.3.6.5. Reminder 1 before Calibration (Required)
If Time Next Calibration (3.3.6.3.) is equal to or less than this value, the
device generates a Maintenance Required reminder.
a) Modify values as required.
b) Set Reminder Activation (3.3.6.4.) to the desired option.
Note: The device always operates in years. Changing the units affects
only the parameter view of the Calibration Interval parameters in
SIMATIC PDM, PACTware FDT, and AMS.
