What Disables Gain Correction?
Gain Correction becomes disabled if certain data collection conditions change
from when the Generate Gain operation was first executed. In all cases, these
conditions are the result of an operator’s change to the spatial acquisition
settings. The disabled condition will occur if changes are made to:
 The camera or pixel format
 The size or location of the custom image
 The lens setting
 Brightness
 Gain
 Shutter
2.1.8 Load Gain…
Restore a previously saved gain correction table from a file. The gain correction
enunciator will turn GREEN if the loaded file will operate under the current setup
conditions. If it cannot operate under the current setup conditions, it will appear
RED.
Note: Perform a Restore Config... using a .usb-cfg configuration file that was saved at
the same time that the .gai gain correction file was created. This will insure that
restored configuration settings will allow the gain correction to operate correctly.
2.1.9 Save Gain As…
Save the current gain correction table to a file. All gain correction files include a
.gai file name extension. The gain correction table must be generated (see
section 2.1.7) prior to saving the table to a file.
Note: Perform a Save Config... and a Save Gain As... operation in conjunction with
each Generate Gain... operation. This will ensure that restored configuration
settings will allow the gain correction to operate correctly.
2.1.10 Gain On/Off
This feature is only available as a button on the toolbar:
Click on this button to toggle gain correction processing off or on. This feature
will only operate once a gain correction table is present. To generate a gain
correction table, perform the steps found in section 2.1.7 or load a previously
generated gain table (see section 2.1.8).
