How to change gratings on the Acton 2500i spectrapro

1)Select the grating you want to use with the following command "ridl_devices,'monochromator','grating',param"
where:
param=an integer value representing the grating number 

2)Uninstall present grating using the follwing command "ridl_devices,'monochromator','uninstall'"

3)Enter the following command to install the grating "ridl_devices,'monochromator','install',param,arg1=arg1,arg2=arg2,arg3=arg3" 
where:
parameter = first number of princeton p/n
arg1= second number of princeton p/n
arg2= third number of princeton p/n
arg3= grating position

Example; For a grating part number of 1-030-2: 
ridl_devices,'monochromator','install',1,arg1=030,arg2=2,arg3=1

4) Run the following command and ensure the information is correct "ridl_devices,'monochromator','?gratings'"

5) Re-Select the grating you want to use with the following command "ridl_devices,'monochromator','grating',param"
where:
param=an integer value representing the grating number 

6)Enter the following command to zero the wavelength "ridl_devices,'monochromator','goto',0"

7)Remove the light source from the monochromator

8)Securely mount a HeNe Laser so that it is directed through the entrance slit of the monochromator

9)Follow steps 6 through 17 in the document below: (Note the alignment mask is located in the grating box for the 300 nm grating)
