TURR (Turret Change) Menu:
The SP-750i comes with a triple grating turret which accepts 1, 2 or 3 gratings. If more than 3
gratings are required, optional interchangeable turrets are available. If your SP-750i has been
purchased with more than one turret (up to three turrets are possible for a total of nine gratings), you must
input the appropriate turret number using the TURR menu each time a turret is changed. For example, if
you switch from turret #1 to turret #2, use the TURR Menu to let the software know you made the change.
This enables the SP-750i and controller to scan correctly and provide correct wavelength display.
To select the Turret Change Menu from the Main Menu, press the white key below TURR on the controller
display. The TURR menu displays, with a dot (■), which grating turret is currently installed in the
SP-750i, along with available turrets. A display of “Not Inst” means that no gratings have been installed
in the specified turret position. For example, the following menu shows that turret #1 is installed with
Grating #1 (1200g/mm) and Grating #2 (300g/mm). It also shows that turret #2 is available, and that
#3 is not installed. To input the correct turret information, press the white key below the numbers 1, 2, or
3 (in this case, nothing will happen if you select turret 3).

JOG Instructions:
The controller for the SP-750i allows the user to change wavelengths without accessing GOTO or
SCAN, and without keying in a destination wavelength. This function is useful for rapidly scanning from
one wavelength region to another, searching for the peak of a line, or accurately positioning a source image
on an array detector. This function is called JOG, and it can be accessed at any time that the other
functions (GOTO, SCAN, etc.) are not in operation. The controller has four direction keys marked with
arrow indicators (▲ ,▼, , and ). JOG operates by moving the SP-750i in wavelength increments
ranging from 0.1nm to 1000nm, and also in “single motor step” increments. Pressing the UP arrow ( )
increases the JOG increment a factor of 10 each time it is pressed, while the DOWN arrow ( ▼ ) decreases
the increment a factor of 10. To access the single motor step JOG, press the DOWN arrow ( ▼ ) until the
increment setting decreases below 0.1nm.
JOG direction is controlled by the arrow keys marked ( and ). To JOG to increasing wavelengths (by
the increment chosen), press the ( ) key. To JOG to decreasing wavelengths, press the ( ) key. If you
press either key more than once, the SP-750i will move the preset JOG increment multiplied by the
number of times the key is pressed. The maximum wavelength possible depends on the grating in the
operating position (1400nm maximum with a 1200g/mm grating, 2800nm maximum with a 600g/mm
grating, etc.). The minimum wavelength possible is -10nm for all gratings.
