3-46 Preparing the Detector
• Tickmarks – This value allows tickmarks to be generated at the
specified wavelength increment to assist in the interpretation of charted
data.
The figures below show a 190 to 600-nm scan of erbium standard in a
cuvette at a pace of 200 nm/min with tickmarks specified every 20 nm
and the same scan without tickmarks.
• AUFS – The sensitivity setting for scaling the charted spectrum.
Scan of erbium standard in a cuvette from 190 nm to 600 nm at a pace
of 200 nm/min with tickmarks every 20 nm
Scan of erbium standard in a cuvette from 190 nm to 600 nm at a pace
of 200 nm/min without tickmarks
Enter these parameters when you select the type of scan, either zero or
sample.
