Zoom

This  shows  an  enlarged  image  of  the  desired  region.  You  can
observe  the  graph  by  zooming  in  and  out  of  spectrum  with  the
method  mentioned  in  the

“Full scale”.

After choosing the

“Zoom”

button, click and drag the cursor over the desired

region with the left button of the mouse pressed, and then you
can see the detailed graph in the scoped area.

Pan

To see a broader spectrum, choose the

“PAN”

button. Click and

drag the graph, then X-axis and Y-axis also change following the
graph movement.

Snap
Shot

Snap Shot makes real-time values halt. When the

“SNAP.S”

button is clicked, the window will be stopped and all other
icons will bec om e inactiv ated. If you click

“SNAP.S”

button again, the icons become active.

Integration Time, Average, & Boxcar

<Fig. 4-3-14>

Integration

Time

Function of spectral signal amplifying. The larger the number, the larger

the signal (increase in detection sensitivity).

If the signal intensity exceeds 16,000 counts, the signal will be saturated

and not be detected. Therefore, the signal should be adjusted below

16,000 counts. In case that the concentrations between samples have

large difference, make the integration time as low as possible.

Average

Function of spectral signal stabilizing. The higher the figure, the more the

signal is stabilized. When the figure is too high, it is hard to get real-time

data. Decide the least figure so the spectral signal of sample does not

move up and down too much. If the real time values of the sample

concentration continue to change very frequently, lower this function to

meet your experiment.

Boxcar

Function of spectral signal smoothing. The higher the figure, the more the

signal smoothes. If the figure is too high, the limit of resolution lowers.

Decide the lowest figure so the spectral signal does not vary much. When

you want to separate intensities of more than two nearby wavelengths,

lower this function to meet your experiment.
