Note: The instrument flashes multiple times per measurement when the
small area view option is employed.
Retro-viewer
The retro-viewer is a lamp in the sphere that allows you to view the sample that is currently at the
reflectance port on a screen. This helps you to determine when the sample is properly placed for
measurement. Turn the lamp on as described below. The sample at the reflectance port is then
illuminated and an image of it appears on the retro-viewer screen. If necessary, adjust the door above
the screen to see a mirror image of the screen display. The retro-viewer lamp must be installed at the
factory.
The retro-viewer lamp has two modes of operation. Select the desired mode of operation using the
retroviewer button as follows:
• Lamp Stay on Mode: Press and hold the retroviewer button until a beep is heard. To turn
the lamp off, press and immediately release the retroviewer button three times in a row.
• Lamp Turn Off Mode: Press and immediately release the retroviewer button. The lamp will
automatically turn itself off when you take a reading.
Note: To prevent heat build-up, the lamp will turn off automatically
after one minute of inactivity, regardless of the mode selected.
Sample Clamp
The UltraScan VIS includes a spring-loaded sample clamp that can be used to hold samples flat and
secure at the reflectance port. The clamp has two buttons, one which raises and lowers the arm, and
one that moves the clamp toward and away from the reflectance port.
