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.

Images look noisy

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 extremly long exposure time, the images can become noisy.

Check gain settings. 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.

Bits that do not change value

If data bits seem to be stuck or do not change, check that the camera is not saturated by preventing light from entering. Run test pattern to verify camera operation insert. Check all cable connections, especially right at the connector; poor connections or broken wires will cause randomly changing bits or stuck bits.

Contact Customer Support

The contact number appears on page two 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. Customer support will frequently request that you e-mail copies of these captured images. See Section 7.
