12.4 Optical Power Adjustment
Procedure
Optical Power Adjustment
WARNING
• While the AQ1200 is producing light, do not remove the optical fiber cable, because light is
emitted from the light source port. Visual impairment may occur if the light enters the eye.
• Close the covers of any light source ports that do not have optical fiber cables connected
to them. On models with two or more light source ports, visual impairment may occur if light
that is mistakenly emitted from the wrong port enters the eye.
Use a short optical fiber to connect an AQ1200 light source port to an AQ1200 optical power
measurement port, and then perform optical power adjustment.
In the loss test screen (see section 12.3) of the slave, press the
LS Power Adjust
soft key to display
the following screen.
Starts optical power adjustment
The measurement light turns on.
When adjustment ends normally, the
AQ1200 returns to the previous screen.
Cancels optical power adjustment
The AQ1200 returns to the previous
screen.
Explanation
Optical Power Adjustment
Adjust the optical power of the light source as necessary.
When you execute optical power adjustment, the AQ1200 automatically identifies the optical power
level and adjusts itself accordingly. Perform optical power adjustment on the light source (slave).
• Optical power adjustment begins when you press the Execute soft key. When it ends normally, the
AQ1200 returns to the previous screen. During adjustment, “Execute” changes to “Abort.” All soft
keys other than the Abort soft key are unavailable.
• Press the Abort soft key to stop optical power adjustment. “Abort” will change to “Execute.” The
adjustment value will return to the value that it was at before adjustment was executed.
• Connect a short optical fiber of a few meters or less in length. Make sure that the fiber is free from
dirt, scratches, bends, and other potential causes of optical degradation.
• The initial adjustment value is the factory default setting.
