5977e msd tuning stopped

Hi all,

 

I tried to autotune out 5977e msd and the following error message appeared after a while: "tune/vacuum control error: the valid range for ent lens offset is 0.00 to 66.50, step 0.0081.

 

Also, there is no signal to be seen om masshunter workstation. Any ideas? Thanks.

  • We have seen something similar to this before and it turned out the brass nuts source was slightly loose. so when it tries to ramp, vibrations distort the ion "beam" and it can't resolve the peaks when ramping.

     

    Try dissembling the source, check the entrance lens for any debris and the n reassemble it and ensure the entrance lens and other parts do not move when "wiggled" a little.
