Initiate Run Time Calibration

Use the Initiate Run Time Calibration option of the Diagnostics menu to initiate a UPS runtime calibration, which determines the UPS battery runtime available to support the current UPS load over time.

A runtime calibration is lengthy, deeply discharges the UPS battery, and temporarily reduces UPS runtime until the battery recharges. Battery capacity must be at 100% to perform a runtime calibration. During the calibration, the battery capacity shown on the Battery Capacity bar graph on the Main Screen decreases.

After you select the Initiate Run Time Calibration option, the menu option changes to Cancel Run Time Calibration, enabling you to cancel the calibration.

Note:
You can use this menu option to perform an immediate UPS runtime calibration even if you turned off scheduled runtime calibrations in the "Schedule UPS Tests" dialog box. See
Self Test Period

During a runtime calibration, the Status field on the Main Screen displays Calibrating.
