9-14
Fig. 9-11. Reset Reference Dark pop-up box.
A pop-up box will prompt you to enter a new reference dark exposure time in
seconds. Click on OK to implement your change. The new reference dark will
be created when you acquire your next image.
Note: Because of the high sensitivity of the CCD, fluctuations in background
radiation and/or temperature in the room can affect the level of dark
count. If you feel that radiation/temperature conditions have changed in
the room since your last reference dark was created, use the Reset
Reference button to delete your old reference and create a new one under
current conditions.
None
If you do not want to perform dark subtraction, select None. No dark
exposure will be acquired or subtracted.
9.6.b Live Acquire Mode
Exposure Count
If you are using the Live Acquire function (see previous section), you need to
specify how many intermediate exposures you want to view/save during
acquisition. Enter this number in the Exposure Count field.
