Set Up Transmitted Illumination
This section provides instruction for setting up the transmitted illumination
controls in order to maximize the illumination signal while minimizing noise.
The basic steps required to set up transmitted illumination include:
ƒ
setting illumination power (percent illumination)
ƒ
adjusting camera gain (KMS-400RT system only)
ƒ
configuring the electronics (frame grabber) controller for gain, offset and
analog gain
To set up transmitted illumination:
1. Place an artifact on the stage and focus at 10X.
2. Position a feature into the center of the measurement screen.
3. From the Measure Screen, select the Window icon and adjust the
measurement window so that it falls across the feature on the screen.
4. Highlight the icon and press [MENU].
5. Set the following values:
ƒ
Gain = 31
ƒ
Offset = 31
ƒ
Analog = 1
6. Use the arrows on either side of the number read-out bar to adjust the
percent illumination up or down so that the upper slide bar floats just below
the point it turns red.
When the percent illumination is correctly adjusted, the bar is white and will
move up and down slightly (Figure 5-5).

Note: You may need to slightly adjust the gain in order to correctly position the bar for
percent illumination.
