The runtime calibration synchronizes the runtime estimate with the current
load and battery capacity. When a runtime calibration initiates, Calibration is
initiated event occurs. A runtime calibration will discharge the batteries. The
batteries will be completely discharged after the calibration. The batteries will
be recharged automatically following a calibration.
Note: Frequent calibration will shorten the life of batteries. We recommend one
or two calibrations per year.
PERFORM A RUNTIME CALIBRATION
1. Click the Start button; this will initiate a runtime calibration.
2. Click the Stop button; this will stop the runtime calibration.
3. Runtime Calibration will display the result after a calibration finishes or you
stop the calibration. The results will report as follows:
• Estimated Runtime: The estimated runtime of the batteries.
• Last Calibration Result: The result of the last runtime calibration.
o
Passed: Runtime calibration passed and the batteries are normal.
o
None: A runtime calibration has not been run.
o
Failed: The Battery Backup failed during the runtime calibration.
o
Cancelled: The runtime calibration was stopped...
• Last Calibration Date: The date the last runtime calibration was performed.
Note: A calibration process causes the batteries to completely discharge. If a
utility power failure occurs during the calibration the Battery Backup will not
support the connected equipment.
