Hand-held fusion
Should the estimated loss be equal or higher than 0.1 dB
(loss highlighted in red), fusion would be incorrect, and the
whole fusion process should be repeated from the start.
8. Equipment cleaning
8.1 Cleaning the splicer's V-shaped groove (V-gro-
ove)
The V-groove's high-precision surface is very sensitive and
should be kept clean.
It is easily contaminated and should be frequently cleaned.
Whenever a constant fibre offset problem appears (screen
displays "OFFSET ERROR"), it always comes to V-groove be-
ing dirty and needing a clean-up.
Follow these steps to clean the V-groove:
Prepare a clean fibre (cut in the cleaver) and push it several
times on the V-groove at a 45o angle, always in the same
direction.
You may see some small particles of dust being swept
away with the fibre during this process.
Besides the mentioned method, you can also clean the V-
groove with a cotton swab moistened with isopropyl alco-
hol. Preferably, combine both methods.
8.2 Electrode cleaning
The fusion splicer electrodes are sensitive and can accu-
mulate impurities due to humidity, dirt, the splicer not ha-
ving been cleaned for some time, etc. To avoid this, regular
cleaning is recommended.
Use the "ELECTRODE CLEANING" function in the menu. It
is recommended as a precautionary measure, to keep the
electrodes clean and problem free.
In extreme circumstances, impurities could be so firmly
fixed that the "ELECTRODE CLEANING" function is not able
to burn the dirt completely. Should it be the case, take a
cotton swab moistened with isopropyl alcohol and sweep
the electrodes to remove the impurities. If this was not
enough, you can use a blade to remove them.

8.3 Oven maintenance

Should the heat-shrink tubes adhere to the oven, you
can grease the oven's lower part with silicone grease. You
should only moisten it, without creating a layer.
