What I would suggest is to adjust the ramp amp and get a download to see in what direction it needs to be, you can have them change it +/- 5mA to see the effect and then keep going in whichever direction. I think that it has to be decreased . It will a while before the spectrum will take effect , be patience.
And you also need to increase the laser current high from 80 to 85.
Download mode 1 & 6 after you see the fit residue changes and forward to us.
