multiple corrections are required to complete the process. The intermediate process does not
require the re-preparation of fiber.
5.7 Propelling Distance Test
Place the fiber with well-prepared cross-
section into the fusion splicer, select the “Propelling Distance
Test” item in the motor menu and press "Enter" button. Press this button again to start the propulsion test.
The process is as follows:
a
）
Fusion splicer automatically pushes the fiber to the center of screen and sets the gap;
b
）
Fusion splicer automatically withdraws the left fiber and propels the right fiber according to the
"o gap" value;
c
）
After the propulsion, fusion splicer automatically calculates and displays the propelling distance
which shall be close to the set value of fusion parameter.
5.8 Discharge Correction
The discharge correction is used to optimize the position of discharge arc and the current. Place the fiber
with well-prepared cross-
section into the fusion splicer, select the “Discharge Correction” and press
"Enter" button. Press this button again to confirm, and start the discharge calibration. The process is as
follows:
a
）
Fusion splicer automatically pushes the fiber to the center of screen and sets the gap;
b
）
Fusion splicer automatically discharges, corrects the arc position and adjust the current;
c
）
If the calibration is not successful, replace the two test fibers with the well-finished
cross-sections according to the instructions, and then fit the windshield and perform another
discharge arc calibration.
5.9 Discharge Test
Select the "Discharge Test" in the maintenance menu. The process is as follows:
a
）
Fusion splicer automatically propels the fiber to the center of screen, sets the gap, and
completes the alignment;
b
）
Electrode discharges and produces an arc, but the right fiber is no longer propelled. Therefore,
the ends of two fibers are burned into the spherical shape;
c
）
Fusion splicer derives the arc position and current intensity from the melting deformation of both
fibers at high temperature, and gives the following information:
“Left/right offset ××× Current ×××” indicates that the arc position deviates to right/left.
Left/right offset of arc is within 003. No adjustment is needed. Current shall be properly between 008 and
012. The offset of arc position is large, and the discharge correction may be performed. If the discharge
correction effect is poor, the electrode holder shall be manually adjusted.
