7.7    Saving of Sample Table   
 
Sample tables can be saved.     
This is convenient for editing the sample table under the same 
name each time.

NOTE:  When six, seven or more spectra are displayed, there 
is a possibility of the spectra becoming too small, or not 
all the traced values can be displayed.    In this case, 
use the Overlay (O) command of Data (D) menu to 
delete unnecessary spectra.

7.9    Check of Photometric Value at Specified Wavelength   
 
This is a function for shifting to the specified wavelength.    It is 
usable for checking the optical axis, etc.   
Open the monitor window and select the Set Wavelength (W) 
command from the Spectrophotometer (S) menu or click the   
(Set Wavelength) button.   
A window as in Fig. 7-24 will open.

Input target wavelength values and click OK.  
Wavelength is now driven to the specified one and a photometric 
value is read on the monitor window.    (Refer to (2) in 1.6.)   
 
 Wavelength drive to zero-order light 
For checking the optical axis, etc. in the zero-order light or 
moving the instrument, wavelength needs to be driven to the 
zero-order light.    Open the window shown in Fig. 7-24 and 
set wavelength at 0.    Then click OK, and wavelength will be 
adjusted to the zero-order light.   
 
NOTE:  For termination with wavelength kept at the zero-
order light, select “Close the monitor window, but 
keep the lamp operating?” in shutting down the 
application (terminating the program).    “Close the 
monitor window, but keep the lamp operating?” must 
also be selected for turning off the photometer 
power supply with the wavelength position kept 
unchanged.

Wavelength scan data files (*.uds) and time scan data files 
(*.udt) can be collectively printed.   
From the File (F) menu, select the collective spectrum recording 
(L) command.    A window as in Fig. 7-25 will appear.

8.    MEASUREMENT USING OPTIONAL ACCESSORIES   
 
 
For the cable connection method for each accessory, refer to the 
instruction manual attached to the accessory.    Explanation is 
given here on operations after setting of your analysis method, 
which is required as instructed in Sections 2 to 5.   
 
8.1    Use of Sample Sipper   
 
Hook up the sample sipper to the spectrophotometer.     
The parameters for the sipper are settable on its front panel.     
Explained here is the procedure for creating a calibration curve 
and measuring an unknown sample in the Photometry mode.   
 
A message box appears in the standard measurement session, 
so operate in accordance with the messages.    A message box 
does not appear in the sample measurement session.   
Measurement can be started just by pressing the sipping lever of 
the sample sipper.   
 
NOTES:  1.  When using the sample sipper, remeasurement, 
interrupt measurement and blank measurement 
cannot be made.    But remeasurement of 
standards is possible.   
2.  When repeat measurement is set, the standards 
will be measured by the set number of times.   
Samples will be measured only once.     
 
Select the Measure command from the Spectrophotometer menu 
or click the          (measurement) button on the toolbar, and the 
window in Fig. 8-1 will open.

Press the sipping lever and measurement starts.    A message 
box for the second measurement now appears.     
For carrying out remeasurement or for skipping the second 
standard measurement, select the relevant item with the mouse 
(put a bullet in its radio button) and then click Yes.   
When clicking No, the current measurement sequence will be 
terminated.   
For restarting measurement, click the    button.   
Measurement then starts from the 1st standard.

On completion of standard measurement, the window in Fig. 8-3 
will open.

By clicking OK with the mouse, a calibration curve is drawn and 
then samples can be measured.    When the window in Fig. 8-4 
appears, you should press the sipping lever.     
Measurement results appear at the area indicated by (1) in   
Fig. 8-5.   
By clicking Cancel, the measurement is terminated, and the 
standards’ data is not saved.     
Now select “Repeat the last measurement” and click OK.   
Set the final standard in place and press the sipping lever.   
When repeat measurement has been set, measurement is 
started from the 1st one (Repl.No.1) for that standard.
