Changes
/* Grating angle change instructions with the temporary brake in place */
- undo the toggle clamps that hold the covers together
- partially retract the south cover of the instrument (it need not be fully removed, just opened enough to be able to access the brake)
- before changing the grating angle, slack off the 4 black M3 bolts on the grating brake (inside the instrument) to release the brake
- in the software, go to the ''Config'' tab, click the ''Unlock'' button, and enter the password
- still on the ''Config'' tab, click the ''Deactivate Grating Brake'' button (this will change to say ''Apply Grating Brake'')
