• ALLOW THE UPS TO DETERMINE THE NUMBER OF EXTERNAL BATTERY PACKS BY

CONDUCTING A RUNTIME CALIBRATION TEST

In order for the UPS to conduct a valid runtime calibration test, the following conditions must be

met.

 The UPS must be 100% charged. This can be accomplished if the UPS is left online,

without power interruption for at least three hours, plus eight hours per external battery

module.

 The load on the UPS must remain constant. A computer or other electronic load

connected to the UPS is usually a good source. Whenever possible, use the load that is

expected to be supported by the UPS.

The runtime calibration test will discharge all connected batteries to 25% of their original

capacity.

See the product documentation packaged with the UPS to install PowerChute.

1. Use any PCBE Console to log on to the PCBE Server that is monitoring the UPS system.

2. Double-click on the UPS system in the Status display’s device list to access the ‘Device

Properties’ dialog box for the UPS.

3. Click ‘Diagnostics’ to display the ‘UPS Calibration’ option.

Note: If the ‘Diagnostics’ selection is not shown, select the ‘Show Advanced

Items’ option at the bottom of the dialog box.

4. Click ‘UPS Calibration’.

5. Click ‘Start’.

If you are unable to install or access PowerChute, or if there is no computer connected to the

UPS, you can conduct a manual calibration by pulling the plug powering the UPS until the UPS

automatically shuts down due to a low battery.
