Arc Calibration
Atmospheric conditions such as temperature, humidity, and pressure are constantly
changing, which creates variability in the arc temperature. This splicer is equipped with
temperature sensor that is used in a constant feedback monitoring control system to
regulate the arc power at a constant level. Changes in arc power due to electrode wear and
glass adhesion cannot be corrected automatically. Also, the center position of arc discharge
sometimes shifts to the left or right. In this case, the fiber splicing position has to be shifted
in relation to the arc discharge center. It is necessary to perform an arc power calibration to
eliminate both of these issues.
Operation procedure
1. Select [Arc Calibration] in [Maintenance
Menu] to display Arc Calibration screen.
2. Set prepared fibers onto the splicer.
3. The ARC Calibration after pressing ENT key.
Arc calibration is performed automatically using [AUTO] mode only. So arc
calibration does not have to be performed when splicing in this mode.
Execute [Arc calibration] before using non-auto mode.
When Performing the [Arc Calibration] function change the arc power “factor” value.
The factor value is used in the algorithm program for all splicing. The arc power value
will not change in the splice modes.
Use standard SMF
ITU-T G652 fiber for Arc Calibration.
Use well prepared fibers for arc calibration. Dust on the fiber surface affects arc
calibration.
Cleave angle threshold does not link to the parameter "Cleave Limit" in splicing
modes. Cleave angle threshold is independently set for arc calibration. See section
[Machine Settings] to change cleave angle threshold.
