AVERTISSEMENT
• Lorsque l’AQ1200x/AQ1205x génère de la lumière, la lumière est émise à travers les
ports de source lumineuse. Ne pas débrancher les câbles de fibre optique connectés. Des
lésions oculaires peuvent être causées si le faisceau lumineux pénètre l’œil.
• Masquer les orifices de source lumineuse sur lesquels aucun câble à fibres optiques n'est
branché. Sur les modèles d'au moins deux orifices de source lumineuse, une déficience
visuelle peut se produire si la lumière
émise par erreur du mauvais orifice pénètre dans l'œil.

Press
AVG
to start the averaged measurement. When the averaged measurement completes,
the fault locations are automatically displayed.
Note
You can save measured data, but saved waveform data cannot be loaded on the Instrument. For details on
saving measured data, see section 18.2.
Explanation
Select Route Menu
Before starting the fault locator feature, you can select the route in which to search for breaks. After
confirming the route, press ENTER. The optimal measurement conditions for the selected route will
automatically be selected.
Fault Location Display
The fault locator uses averaged measurements to detect faults. The cursor position is automatically
set to a fault location on the waveform, and the distance from the measurement reference point to the
fault is displayed.
Faults are not detected during real-time measurement. In the fault locator’s real-time measurement,
you can perform cursor operations or select the wavelength during measurements. If you cancel
measurements prematurely, faults will not be detected.
Distance Unit
You can select the distance unit that is displayed on the screen from the units shown below.
km, mile, kfeet
If you set the Instrument language to JAPANESE, the distance unit is fixed to km. For the setup
procedure, see section 5.5.
