The UPS has a diagnostic feature that indicates the utility voltage.

The UPS starts a self-test as part of this procedure. The self-test does not

affect the voltage display.

Press and hold the Test button to view the utility voltage bar graph indicator.

After a few seconds, this five-LED Battery Charge indicator on the right of

the display panel will show the utility input voltage.

Refer to the figure on the left for the voltage reading (values are not listed on

the UPS).

The indicator on the UPS shows the voltage is between the displayed value

on the list and the next higher value (see Troubleshooting).
