Fig. 4-4. Selecting Auto Expose.
Once an image has reached the specified percentage of saturated pixels, it is
captured and displayed in the video display window, Auto Expose is
automatically deactivated, and the exposure time appears active in the
Exposure Time field.
At this point, if you are in UV or White image mode, Manual Expose will be
automatically activated. If you are in Chemi mode, the Freeze button will be
automatically activated.
Note: If you are having difficulty auto-exposing your sample, you can use
Manual Expose to adjust your exposure time directly. Most non-chemi
applications only require an exposure time of a few seconds, which can be
quickly adjusted using Manual Expose.
Manual Expose
If you know the approximate exposure time you want, you can click on the
