If you get noimage at all when you attempt to capture an image with the frame grabber, use the chart thatappears in Section 8.4.1 on page 295.YesYesNoUse the CCT+ to activate the factory configuration setand then capture a few normal images.Is the problem still present?One of the camera’s settings wassignificantly misadjusted. Review thecamera manual to make sure that youare setting the camera correctly.NoUse the Camera Configuration Tool Plus (CCT+) to set the camera for test image one.Capture several images and carefully check the pixel values in each image. (Most framegrabbers include software tools that allow you to see the individual values of each pixelin the image and histograms that display distributions of the pixel values in the image.)The pixel values in your captured test image should be exactly as described inSection 6.7 on page 186. Also, if you capture several test images, the pixel valuesshould be the same in all of the captured test images.Are the test images OK?Go to the interfacingtroubleshootingchart.Contact Basler technical support. The contact numbers appear on the front pages of this manual.Before you call for support, be sure to make note of the camera settings and the frame grabber settings you areusing. You should also have a captured live image and a captured test image available. Basler technical support willfrequently request that you e-mail copies of these captured images.Exit this chart.YesImages are toobright or too dark.Images look noisy. Other imageproblems.Make sure that the lens cap has beenremoved.Check the lens aperture. If the images aretoo dark, try opening the aperture. Tryclosing the aperture if they are too bright.Check the exposure time. If the images aretoo dark, try increasing the exposure. Trydecreasing the exposure if they are toobright.Check your light source. If the images aretoo dark, try increasing your light intensity.Try decreasing the intensity if they are toobright.Check your gain setting. If the images aretoo dark, try increasing the gain. Trydecreasing the gain if they are too bright.Check whether a parameter error hasoccurred. If the images are black, make sureall parameters are set within the valid rangesand to valid values.Has the problem been corrected?Make sure that you are using a DC lightsource. Using an AC light source can makeimages appear noisy.Make sure that the camera has properventilation. If the camera becomesextremely hot, it may produce noisy images.Check the exposure time. If you use anextremely long exposure time, the imagescan become noisy.Check your gain setting. Using a very highgain setting can cause noisy images.Examine the objects that you are imaging.Objects with characteristics such aschanging surface texture or reflectance willproduce images that appear noisy.Has the problem been corrected?NoExit this chart.Yes No
