Set the Key Position
You can attach the MPO inspection tips to the probe with the MPO
key on the left or right, as shown in Figure 6. This lets you rotate
the probe when a cabinet door or other surface is in the way of the
probe's handle (Figure 7).
The Key Position setting at the bottom of the Live View screen lets
you make the fiber numbers on endface diagrams agree with the
numbers on the connector.
To see the correct numbers for the fibers in your test results
• For key up/key down adapters: Set the Key Position to the key
position you use on the probe.
• For key up/key up adapters: Set the Key Position to the
opposite side from the key position you use on the probe.
When you set the Key Position correctly for the type of adapter,
fiber number 1 is in the upper-right corner of the endface image.
