5. Read the sample.
Note: The instrument flashes multiple times per measurement when the small area view option is
employed.
Retroviewer
The retroviewer 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 retroviewer screen. If necessary, adjust the door above the
screen to see a mirror image of the screen display. The retroviewer lamp must be installed at the
factory.
The retroviewer lamp has two modes of operation:
1. The lamp stays on between readings.
2. The lamp turns off after each reading.
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: In order 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.
