Use them in compliance with the following. This may result in damage to the fiber cable.
- Fiber cable bend radiuses must be at least 20 mm.
- Do not yank hard on a fiber cable.
- Do not step on a fiber cable or place anything heavy on it.
- Do not apply any twisting stress to the fiber cable.
- Do not forcefully insert, or bend, or twist in a manner that would cause stress o
n the fiber connector when 
connecting it.
- Do not let bending cause stress at the root section of a fiber connector and
 connection.
• Do not touch the end surface of a fiber cable, or the cable ma
y be degraded in performance. Should the end surface 
be touched or soiled, wipe the dirt away using a commercially available cleaner exclusive for fiber or dry and soft 
cloth. Do not use a cloth moistened with alcohol, or the dirt may be reattached.
• Use optional ZW-XCL or commercially a
vailab
le fiber cleaner when cleaning the groove of the fiber connector. For 
how to clean the fiber connector using ZW-XCL, refer to the

• Calibrate the Sensor Head after removing and inserting a fiber cable.
Calibrating Sensor Head p.66
• For checking the fiber is broken, confirm the followings. 
Confirm by looking the Sensor head is lighting with 
connecting to Sensor Controller. To put the diffraction, i.e.. a 
paper to around the measurement center of Sensor head, you can confirm by looking. 
When the measurement of the high reflection, you may not confirm by
 looking due to adjustment of intensity 
automatically.
• Cleaning the fiber connector and fiber cable using ZW-XCL, f
ollow the procedures.
