This menu indicates there are two main selections for operation: SP300 selects the
menu for normal SP300i/500i operation. UTIL selects lesser used utility functions
for the monochromator. Pressing the function key below SP300 brings up the
following menu. GOTO SCAN SPEED GRAT TURR DIVTR
and pressing the NXT key displays the remaining functions of this menu SLITS
and QUIT.
GOTO:
Press the function key below the GOTO command. The following screen is
shown: Go to:
Enter wavelength <
Key in the desired wavelength in nm ( up to two digits after the decimal ) and press
the ENTER key. The monochromator will move quickly to the selected
wavelength and display this wavelength.
SCAN:
Press the function key below the SCAN command. The following screen is
shown:
Scan To:
Enter wavelength <
Key in the desired wavelength in nm and press the ENTER key. The
monochromator will scan at the constant rate previously selected to the wavelength
just selected.
SPEED:
Press the function key below the SPEED command. The following screen is
shown: Scan Rate:
Enter Speed <
Key in the desired speed in nm/min ( maximum speed for a 1200 g/mm grating is
1000 nm/min; see monochromator manual for other rate limits). Future scans will
use this rate until the rate is revised.
