4.2.6 Automatic Calibration Dialog Box
You should perform all three types of calibration: static, scanning, and scan speed
compensation. This lets you subsequently use any data acquisition mode. It also lets you
change mass ranges and scan speeds while maintaining correct mass assignment.
1. Select Calibration > Calibrate Instrument from the Tune window. The Calibration
window appears ( Figure 4-1 ).
2. Select Calibrate > Start Acquisition from the Calibration window. The Automatic
Calibration dialog box appears ( Figure 4-9 ).

3. Specify the type or types of calibration you intend to perform: Static , Scanning ,
and/or Scan Speed .
Note: For a complete calibration, select Static Calibration , Scanning Calibration ,
and Scan Speed Compensation in the Types area. Then, in the Process area,
select Acquire & Calibrate and Print Report .
Considerations
Though Waters suggests you perform all three types of calibration, you can nevertheless
specify one, or any combination, of calibration types. Beware, however, that doing so
invokes the following limitations:
• Specify Static to calibrate only for acquisitions where the quadrupole “parks” at a
single mass (for example, SIR acquisitions).
