Figure 45 Zeroing Screen
N O T E
If you see the screen shown in Figure 46, the zeroing operation has
failed because the Power Meter received light. The most common
reason for zeroing to fail is if:
• a source is connected to the Power Meter's input connector,
• the fiber connected to the Power Meter's input connector is
collecting light, or
• the Power Meter receives ambient light because the input connector
is uncovered.
Press Enter and start again at step 1.
4 When the zeroing operation finishes, press the [Close] softkey to
close the menu.
