Grading Fiber: Pass Fail Criteria Dirt & Defects Pass/Fail criteria for AT&T can be found in the following section of ATT-TELCO-002 -200 -381: The Universal Grading Template is only used when there is a defect that can not be removed in the cleaning process described in ATT-TELCO-002 -200 -381 29

Grading Fiber: Pass Fail Criteria Dirt & Defects 30 • Identify the debris and defects which can not be removed • To grade these defects, place the template over the fiber on the “low” side • Use the “Keys to Zone” section of the template to determine in which zone the identified defects are located • Use the reference dots on the template to identify the size of the defects • Refer to the appropriate table for Pass/Fail Criteria in ATT-TELCO-0020200 -381

Grading Fiber: Pass / Fail Criteria 31 • The following Pass/Fail criteria can be found in ATT-TELCO-002 -200 -381 • Suggestion: Keep this criteria readily available when inspecting (print and keep in kit with grading guide).

Maintenance Contamination In general, this kit requires little or no maintenance. However, there are issues that can arise and it’s important to know how to recognize when the unit needs service. If the optical system becomes contaminated, it can degrade the image quality. There are 3 symptoms of this condition: 32 • Camera Sensor Contamination • Lens Contamination • Tip Contamination Note: All service work is performed at Westover Scientific’s factory just outside Seattle, Washington.

Camera Sensor Contamination This sort of contamination will show as a black spot. These spots look like dirt on the fiber and it can be difficult to determine if the dirt you see is on the fiber or on the camera. There is a simple way to discern the difference. If you suspect the camera may have been contaminated: Insert a fiber, focus and rotate the probe or the fiber… • If the black spot stays in one place on the display while the image moves, then there is dirt on the camera and it is in need of service • If the black spot moves around the display with the fiber image, then it is on the fiber Black Spot (Dirt) Camera Sensor Contamination 33 Note: All service work is performed at Westover Scientific’s factory just outside Seattle, Washington.

Lens Contamination If there is a lens contamination, it creates a brown or gray shadow on the display image. Most users will never notice this, but if you do and would like to fix it, ship it back to the factory for cleaning. This type of contamination does not impact the scope’s ability to perform well, as you can still see and discern all details of the fiber. Lens Contamination 34 Shadow Note: All service work is performed at Westover Scientific’s factory just outside Seattle, Washington.

Tip Contamination The tips in this kit all have self-contained, recessed imaging lenses within them. As such, they can become contaminated through regular use. Contamination of these lenses will not affect the image until they are heavily covered. If this occurs, the image will become uniformly cloudy. You will see a haze across the entire image Tip Contamination 35 Note: All service work is performed at Westover Scientific’s factory just outside Seattle, Washington.

Maintenance The probe and display are ruggedized and should fair very well over their life in the field. Nevertheless, they are electro-optical devices and should be handled with care whenever possible. The tips are somewhat more sensitive and should be protected as best possible. All of the tips should be stored in the provided plastic bags and hard case when not being used. 36
