TroubleshootingBASLER L400k 6-5Draft6.2.2 Poor Quality ImageUse this chart if the image is poor quality, is completely white, or is completely black. If you get noimage at all when you attempt to capture an image with the frame grabber, use the chart thatappears in Section 6.2.1.Go to the interfacingtroubleshooting chart.YesYesNoUse the CCT+ to activate the Factory Set then andcapture 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 pixel inthe 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 in Section3.10. Also, if you capture several test images, the pixel values should be the same inall of the captured test images.Are the test images OK?Capture several lines and check the pixel values in each captured line.(Most frame grabbers include software tools that allow you to see theindividual values of each pixel in the captured lines and histograms thatdisplay distributions of the pixel values in the lines.)Are the pixel values in each captured line identicalto the pixel values in all of the other captured lines?Do all captured images appear to be completely black or very dark.Use the CCT+ to activate the Factory Set. Once theFactory set is activated, capture several images.Is the problem still present?YesYesNoYes NoA parameter error was present.A parameter error occurs when aparameter is set out of range, aparameter is set to a value that is notallowed or when parameters thatdepend on each other are set toconflicting values. If you are settingthe camera’s parameters by usingbinary commands to write toregisters, make sure you check themin, max and increment fields ofeach register before you set theparameter value.Contact Basler Technical Support. Thecontact numbers appear on the titlepage of this manual.Before you call for support, be sure tomake note of the camera settings andthe frame grabber settings you areusing. You should also have a capturedlive image and a captured test imageavailable. Technical support willfrequently request that you e-mailcopies of these captured images.No
