  • Page 32: Zeroing Operational Defects

    Operational defects refer to the reliability of the image intensifi- ers and are an evidence of instability. Their identification shall be a valid reason to immediately refuse to accept the ATN PS-40. These include shading, edge glow, flashing, flickering, and inter- mittent operation.

  • Page 33: Edge Glow

    However, some types of blemishes can get worse over time and interfere with the usabil- ity of the device. If you believe a blemish is a cause for rejection, warranty or repair please ATN or point of purchase for warranty/ repair procedures.
  • Page 34 A bright spot is a small, non-uniform, bright area that may flicker or appear constant (Figure 3-3). Not all bright spots make the ATN PS-40 rejectable. Cup your hand over the lenses to block out all light. If the bright spot re- mains, return the ATN PS-40.
  • Page 35 C. Black Spots. These are cosmetic blemishes in the image intensifiers or dirt or debris between the lenses. Black spots are acceptable as long as they do not interfere with viewing the image. No action is re- quired if this condition is present unless the spots interfere with the usability of the device.
  • Page 36 E. Chicken Wire. An irregular pattern of dark thin lines in the field of view either throughout the image area or in parts of the image area (See Fig- ure 5-5). Under the worst-case condition, these lines will form hexagonal or square-wave shaped lines. This is typically viewed in high light conditions.
