5.14.10 Tension Monitor
The Tension Monitoring System is used in all Vytran glass processors to provide feedback on the taper process.
At system turn on, the tension monitor (shown in Figure 37) needs to be zeroed to ensure proper reading of tension
being applied to the fiber. This is done by opening the Tension Monitor (View

Tension Monitor), ensuring no
force is being applied to the desired fiber holding block and clicking on "Tension Base" process in the Process Bar.
Utilizing the Tension Monitor, the user can pre-load a tension to the fiber before the taper process, and then use
the feedback to modify the taper properties as needed. The "Taper Tension" process is available to allow the user
to define a target tension to apply prior to the tapering process, or any other process.
As an example, a standard 400 µm to 200 um taper should be pre-tensioned by approximately 20 g. This is typically
done by moving the left fiber holding block to the left using the motor control bar using fine steps manually or by
running the "Taper tension" process with a 20 g target. During the taper process, if the tension drops down to 0 or
negative values, the start power should be decreased because the glass has been softened too much or possibly
melted. If the tension goes very high, increase the start power because the glass has not softened enough.
