Description
Data Int.
Set up a data interval. “Normal” and “Fine” are
selectable.
[1] Normal : Usually selected.
[2] Fine
: Permits measurement at short data
intervals as compared with Normal.
However, noise is more likely to be
generated on a spectrum, because the
data acquisition time per point is
shorter than when Normal is selected.
The actual data interval differs
depending on the scan speed and
measuring wavelength range.
Whichever is longer is made effective.
In case of scanning at 400 nm/min in a
range of 600 to 400 nm for example,
the data interval is set to 2 nm when
Normal is selected, and to 1 nm when
Fine is selected.
