Select the requested standard from the set.
Labels on the top of each standard identify
the number of the standard. Approximate
transmission values are as follows:
• T01 0.25 AU (Absorbance Units)
• T02 0.50 AU
• T03 1.0 AU
• T04 2.0 AU
• T05 2.5 AU
Absorbance values vary across the spectrum,
as well as from set to set. Always use the
same set, with the labeled mini-CD.
Position the standard in the sample drawer
with the label facing the user.
When the T01 standard has been scanned,
the result will be plotted as shown.
In this picture, the upper and lower spectra
are tolerances from the initial IPV Setup
spectrum. The IPV Setup spectrum is the
dark spectrum in the middle, displayed in
black on screen.
The lighter spectrum in the middle (red on
screen) is the current spectrum. It should be
within the upper (blue) and lower (green)
spectra as shown.
