3.4 Cleaning Objective Lenses
If the objective
lenses’
surface becomes dirty, normal observation of the
core position may be incorrect, resulting in higher splice loss or poor splicer
operation. Therefore, clean both of them at regular intervals. Otherwise,
dirt may accumulate and become impossible to remove. Cleaning Objective
Lenses
◇
<1> Before cleaning the objective lenses, always turn off the splicer.
Do not hit or touch tip of electrode when cleaning it.
<2>Gently clean the surface of lenses (X-axis and Y-axis) with an
alcohol-impregnated thin cotton swab. Using the cotton swab, start at the
center of the lens and move the swab in a circular motion until you spiral
out to the edge of the lens surface. Remove excess alcohol from the mirror
surface with a clean dry swab. The lens surface should be clean and free of
streaks or smudges.
<3> Turn on the power and make sure no smudges or streaks are visible on the
monitor screen. Press X/Y to change the screen and check the state of
the lens surface on both the X- and Y-screens. Perform dust check.
3.5 Replace Electrodes
Electrodes wear with use and also must be cleaned periodically due to
silica oxide buildup. It is recommended that the electrodes should be replaced
