Defective Pixel Repair

When using the device, defective (dead) pixels may appear on the microbolometer. These are bright or dark points of a constant brightness that are visible on the image.

Krypton XG50 thermal imagers allow the user to remove any defective pixels on the sensor using firmware as well as to cancel removing.

  1. Press and hold the MENU (7) button to enter the main menu.
  2. Use the RIGHT (6)/LEFT (8) buttons to select the Defective Pixel Repair  menu item.
  3. Press briefly the MENU (7) to open the submenu.
  4. Select the Defective Pixel Repair  option by briefly pressing the MENU (7) button.
  5. A marker (H)  appears on the left side of the display.
  6. On the right side of the display appears a "magnifying glass" (G) - a magnified image in the frame with a fixed cross , designed for easier detection of a defective pixel and to match the pixel with the marker, and horizontal and vertical arrows for X and Y axes (I) showing the marker's movement.
  7. With a short press of the RIGHT (6)/LEFT (8) buttons move the marker to align it with a defective pixel.
  8. Switch the direction of the marker from horizontal to vertical and vice versa with a short press of the MENU (7) button.
  9. Align the defective pixel with the fixed cross in the frame - the pixel should disappear.
  10. Delete the defective pixel with a short press of the ON/OFF (9).
  11. Once the pixel has been successfully deleted an "OK" message will briefly appear on the screen.
  12. You can then delete another defective pixel by moving the marker across the display.
  13. Exit the Defective Pixel Repair submenu with a long press of the MENU (7).

Warning! The display of a thermal imager may have 1- 2 pixels represented as bright white or coloured (blue, red) dots which cannot be deleted and are not a defect.
