The “INPUT VOLTAGE: XXXV; OUTPUT VOLTAGE: XXXV” screen displays
the actual input utility voltage level as well as the actual voltage level being output to
the connected devices.
NOTE: As shown in the illustration below, at times, the voltage values on the
screen may not match. This may be because separate circuits are used to make these
voltage measurements and there is a time delay between the two circuits when
updating the status screen. This condition is considered part of the normal operation
of the unit.

The “INPUT FREQ: XXHZ; OUTPUT FREQ: XXHZ” screen displays the actual
input utility voltage frequency as well as the actual voltage frequency being output to
the connected devices.
NOTE: At times, the frequency values on this screen may not match. This is
because separate circuits are used to make frequency measurements and there is a
time delay between the two circuits when updating the status screen. This condition
is considered part of the normal operation of the unit.
