calibrated by the Hohenstein Institute in Germany. Instructions for using UV control are described in
the Standardization section.
Medium Area View and Small Area View
The medium area view (MAV)/small area view (SAV) feature includes MAV and SAV lenses, port plates,
and a retroviewer (lamp in the sphere that allows viewing of the sample in a flip-up mirror for
determining the proper placement of samples). To use the MAV/SAV feature:
1.
Remove the original port plate from the reflectance port and replace it with the MAV or
SAV port plate, as desired.
2.
Standardize the instrument. Be sure to select 0.390 inch (9.906 mm) [MAV] or 0.190 inch
(4.826 mm) [SAV] as the area view in the Setup Mode window in EasyMatch QC. The lens
will automatically adjust.
3.
Place the sample at the reflectance port.
4.
Press the retroviewer switch on the top left of the sensor (about halfway back). The sample
is illuminated, and an image appears on the screen on the top of the sensor. If necessary,
adjust the door above the screen to see a mirror image of the screen display.
5.
Be sure that the sample completely covers the reflectance port. Adjust the position of the
sample if necessary.
6.
Read the sample.
The
