Next, set the maximum wavelength of scan range.
SCANNING WL RANGE (WL1 WL2) nm
<250 – 600>
Press [numerical] keys (within [2][5][0] to [9][0][0]), and then
the [ENT] key.
* Enterable range: Minimum scan range is 50 nm.
Measuring span is max. 400 nm.
Input the number of spectral data.
MEMORIZE SPECTRUM NO. (1–3)
_
Press [numerical] key (within [1] to [3]), and then the [ENT]
key.
During spectrum acquisition, the following screen is
presented.
SCANNING SPECTRUM NO.: 1 MODE: ABS
WL: *** nm
Upon completion of spectral data storage, the monitor
screen automatically appears.
NOTE: The stored spectral data is a value after automatic
subtraction of the background spectrum.
Therefore, before spectrum measurement, correct
background spectrum should be stored in
memory. If acquisition of spectral data has been
attempted without acquisition of background
spectrum, the following screen appears.
