Wind-protector motion and sheath clamp motion
This unit has automated Wind-Protector opening-and-closing mechanism
and movement changes with the chosen operation mode.

* When the power supply is off, "Wind-Protector" state is closed.
So please be sure to press a power button and to turn off a power supply.
Time after setting a fiber until "Wind-Protector" closes is short with "Auto"
and "fast" mode, and is little longer with "Normal" mode.
Time after setting a fiber until "Wind-Protector" closes can be changed in
"customized" mode.
Moreover, sheath clamp motion differs by ON/OFF of the "proof test" setup
in splice mode.

As it is shown in the above-mentioned table, the sheath clamp motion after the
end of connection changes with ON/OFF of a "proof test" setup in splice mode.
Arc Calibration
Atmospheric conditions such as temperature, humidity, and pressure are
constantly changing, which creates variability in the arc temperature. This
fusion 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 the Arc Calibration icon in the [READY] screen.
2.
Load prepared fibers into the fusion splicer.
3.
Press SET key to initiate the ARC Calibration.
4.
A message appears after Arc Calibration. Please check it and take the
appropriate action displayed with the message.

Arc calibration is performed automatically using [AUTO] mode
only. Therefore, 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
