Calibrate display – Lets you calibrate the raw data peaks in the upper graph of the
Calibration report. As you select each peak, the display recalibrates, bringing the other
spectral masses into line.
4.2.5 Mass Measure Dialog Box
Mass measure parameters control conversion of raw continuum data to centroid data,
which the calibration process requires. You must therefore specify them before calibrating
in ESI mode.
Note: If you use centroid data for calibration, you need not specify mass measure
parameters.
Select Edit > Calibrate Quad Mass Measure Parameters from the Calibration window
( Figure 4-1 ). The Mass Measure dialog box appears ( Figure 4-8 ).
