Issue Description 

Using DiscoveryQuant 2.1.3 Quick Tune will set the DP value to 0 and then Fine Tune will fail as it has an invalid DP value.  The temporary Q3 MI scan method for the quicktune will show the MH+ ion with 2 DP scans both at 200v (though this voltage may vary).  The cause is incorrect DP settings in the parameter settings for the instrument.

  2. Deactivate Hardware Profile in Analyst
