Runtime Calibration

The Runtime Calibration ensures the runtime estimate is accurate with the current load. The results show the

runtime, the result, and the date of the last calibration. When a runtime calibration is initiated, the connected

equipment will be run on battery power until the batteries are completely discharged. The batteries will be then

automatically recharged following the calibration.

Users can click the Start button to initiate a runtime calibration. Click the Cancel button to interrupt the runtime

calibration. The result will be reported after a calibration is finished or canceled:

 Estimated Runtime: The estimated runtime of the batteries.

 Last Calibration Result: The result of the last runtime calibration.

 Passed: The runtime calibration completed and the batteries are good.

 None: The UPS has never performed a runtime calibration.

 Failed: The UPS failed during the runtime calibration.

 Canceled: The calibration was interrupted.

 Last Calibration Date: The date the last runtime calibration was performed.

Note: It is recommended to perform at least one calibration every 3 months.

Note: A complete calibration causes the battery capacity to deplete, Ensure the UPS is recharged completely after

performing a calibration.

Alarm Test

The Alarm Test allows users to verify that the alarm can beep normally and shows the date of the last test. Click the

Initiate button to begin an alarm test.

The details will be reported after an alarm test is complete:

 Last Processing Date: The date the last alarm test was performed.

Indicator Test

Indicators on the front panel or on the LCD screen are used to present the UPS status. Once the indicators are

malfunctioning, users won’t know the current UPS status. The Indicator Test allows users to ensure whether

indicators blink normally. Click Initiate button to begin an indicator test.

The details will be reported after an indicator test is complete:

 Last Processing Date: The date the last indicator test was performed.

Load

The UPS supplies power to generic equipment and shutdown-protected computers that connect to native outlet

sockets of UPS or extended PDU. The UPS/Load page provides detailed information about connected loads and the

extended PDU.
