Use the CCT+ to set the camera for test image one. Use your frame grabber to capture
an image and examine the image carefully. (Most frame grabbers include software tools
that allow you to see the individual values of each pixel in 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 in section
3.11. Also, if you capture several test images, the pixel values should be the same in all
of the captured test images.
Are the test images OK?
Contact Basler technical support. The contact numbers appear on the title page of this manual.
Before you call for support, be sure to make a note of the camera settings and the frame grabber settings you are
using. You should also have a captured live image and a captured test image available. Technical support will
frequently request that you e-mail copies of these captured images.

Use the CCT+ to copy the Factory Set to the Work Set.
Take the camera out of test image mode and capture a
normal image.
Is the problem still present?
One of the camera’s settings was
significantly misadjusted. Review the
camera manual to make sure that you
are setting the camera correctly.
No
Images are too bright or too dark. Images look noisy. Other image
problems.
Do the following:
Make sure that the lens cap has
been removed.
Check the lens aperture. If the
images are too dark, try opening the
aperture. Try closing the aperture if
they are too bright.
Check the exposure time. If the
images are too dark try increasing
the exposure. Try decreasing the
exposure if they are too bright.
Check your light source. If the
images are too dark, try increasing
your light intensity. Try decreasing
the intensity if they are too bright.
Check your gain setting. If the
images are too dark, try increasing
the gain. Try decreasing the gain if
they are too bright.
Check the offset settings.
Check the digital shift setting.
Has the problem been corrected?
Do the following:
Make sure that you are using a DC
light source. Using an AC light
source can make images appear
noisy.
Make sure that the camera has
proper ventilation. If the camera
becomes extremely hot, it may
produce noisy images.
Check the exposure time. If you use
an extremely long exposure time,
the images can become noisy.
Check your gain setting. Using a
very low or a very high gain setting
can cause noisy images.
Examine the objects that you are
imaging. Objects with
characteristics such as changing
surface texture or reflectance will
produce images that appear noisy.
Check the long exposure
compensation setting.
Check the digital shift setting.
