N o. of w avelengths used in quantitative analysis. S elects optim um
num ber. of w avelengths (1, 2, or 3) according to the sam ple condition.
1-w avelength:
F or com m on solution sam ple. S ee F ig. 4.13 (1).
2-w avelength:
F or baseline correction. S ee F ig. 4.13 (2).
3-w avelength:
F or baseline correction. S ee F ig. 4.13 (3).
In [3-w avelength], the absorbance value is obtained from the follow ing

[S am ple N o.]
S ets the sam ple num ber for m easurem ent. S am ple num ber increases
increm entally by one w ith each subsequent m easurem ent.

S ets how m any tim es each sam ple is m easured. If 2 or m ore
m easurem ents are set, the [C ycle T im e] field appears.
[C ycle T im e]
S ets the tim e in seconds betw een m easurem ents. If the cycle tim e is
shorter than the m easurem ent tim e, the next m easurem ent starts
im m ediately.
Input range: 0 to 15000 sec.
