nected, we recommend that you set the gain to 16.
• If the recommended value is exceeded, the brightness will not be stable and measurement values may be
inconsistent. We recommend that you turn ON the Brightness Connection Mode.
If a slow shutter speed (1/1 to 1/10) and a high gain are set, fixed-pattern noise (fleck and striped noise)
will sometimes occur. Be sure to thoroughly check the images and the measurement results when you
set the shutter speed and gain.
