At the bottom of the page, first enter the desired wavelength value by pressing nume-
ric keys
(0~9)
(4.2).
Ce
key (4.3c) is used to cancel previous data. After setting the starting
wavelength, the system asks the user to set the ending wavelength. Press
Enter key
(4.3d)
to confirm the numeric entry, then quit by pressing
Return
(4.3e). If there is no data to add,
press
Return
key (4.3e) to exit this page directly. The program permits setting a 5-digits
number in a range from 190 to 1100. In case the number you set exceeds five digits, the
system will delete what has been entered and you should enter new data.
If the ending wavelength value entered is higher than the starting wavelength value, an
error message will be displayed. Thus, you should enter it again.
Setting ordinate full scale range
Press
(5)
key to display the ordinate
(measured value) full scale range setting
page shown as picture 21.
At the bottom of the page, the system
indicates user to set the upper limit of
the ordinate. Press numeric keys
(0~9)
,
(.)
and
(-)
(4.2) to enter the desired value.
Ce
key (4.3c) is used to clear previous
data. After setting the upper limit, the
system indicates user to set the lower
limit. Press
Enter key
(4.3d) to confirm
the numeric entry and quit by pressing
Return
(4.3e). If nothing is to be entered,
press
Return
key (4.3e) to quit directly. The program permits setting a 4-digits number in
a range from -9999 to 9999. If the figure entered exceeds four digits, the system will dele-
te what has been entered. Thus, you should enter it again.
Dark Current Adjustment
Press
(F5 )
key to carry out dark current adjustment. The dark current adjustment is to
be done, as shown in picture 22.
Quitting parameter setting
Press
Return
key (4.3e) quit parameter
setting operation and return to the main
menu of spectrum scanning.
Setting measuring wavelength
On the main menu of spectrum scan-
ning, press
GoTo WL
key (4.4b) to display
the following page (pic. 23) and set the
measuring wavelength for spectrum
scanning.

Baseline correction
On the main menu of spectrum scanning, press
Autozero
key (4.4a) to start baseline
correction at the set wavelength range. Before starting baseline correction, put the white
sample into the sample compartment.
Start/Stop
key (4.4c) can be pressed to stop baseline
correction operation. If the wavelength range has been changed, the baseline calibration
should be done again.
Measuring operation
On the main menu of spectrum scanning, press
Start/Stop
key (4.4c) to start spectrum
scanning measurement. The measured spectrum will be displayed dynamically, as shown
in picture 24. When the scan is to be stopped, press
Start/Stop
key (4.4c) again.
A maximum of 1100 points can be sto-
red for one spectrum, because the
memory space of micro-processor is
limited. If the set wavelength range is
wider than 110nm and the sampling
interval is set to 0.1nm, the system will
change it to 1nm automatically. In other
circumstances, the setting will not be
changed.
