Arc Calibration
1.
The necessity of 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 and pressure sensors that are used in a constant feedback monitoring
control system to maintain the arc power at a constant level. Changes in arc power due
to electrode wear and glass adhesion cannot be corrected for automatically. Also the
center position of arc discharge may shift 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 either of these issues.
This machine has two kinds of calibration functions. [Arc Calibration] & [Special
Arc Calibration]. Generally, the standard [Arc Calibration] is used for normal 125
µm fibers spliced under standard arc settings (such as 1 mm electrode gap). For large
diameter fibers, other fibers that require a larger electrode gap or other special
conditions such as V Height Shift (vertical displacement of the fiber location up or
down relative to the electrodes), or small or heat-sensitive fibers, the [Special Arc
Calibration] should be used. This is summarized in the table below. Please refer to
the previous section [Function Introduction] for details concerning [Auto Arc
Calibration], [Arc Center Compensation], and [Auto Time Comp.] which are related
functions.
If the strength of arc discharge has changed due to significant change of
atmospheric pressure, an error may occur during arc calibration. To solve
this problem, perform [Stabilize Electrode].
