INPUT FREQUENCY/OUTPUT FREQUENCY Screen
This screen, shown in Figure 24, shows 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 for updating this status
screen. This condition is considered unit normal operation.
