* The software knows which order-blocking filters should be used with each grating, but it is still a good idea to check that the correct filter is selected (refer to the table above). If necessary, select the required filter from the drop-down menu at the bottom of the ''Instrument Setup'' pane and click ''Go''.
 
TECHNICIAN'S GRATING ANGLE CHANGE INSTRUCTIONS:
- Before changing the grating angle, disable the physical brake on the grating, inside the instrument
- In the software, go to the configuration tab, push the "Unlock" button, and enter the password.
- Still on the config tab, push the "Release Grating Brake" button (this will change to say "Apply Grating Brake").
- After the grating brake has been released in software, the reset, initialize, grating angle entry and grating angle "Go" buttons should all be enabled.
- Reset and/or initialize if necessary.
- In the main control tab, enter the required grating angle and push the "Go" button.
- Once the grating has finished moving, push the "Apply Grating Brake" in the config tab.
- Lock the config tab.
- Enable the physical brake on the grating, inside the instrument.
