Details of Calibration Point
The Details of Calibration Point dialog lists the recalibrations of the given level for the specific compound. Based on the checked recalibrations, the final calibration point for the given level is calculated.
Use the Calibration - Show Details command or click 
on the row of the level, to invoke the Details of Calibration Point dialog.
The graph displays the calibration curve for the selected compound - Nitrogen in this case. If the Used check box ① , in the Levels Table, is not checked, the calibration curve will not use the calibration level in the construction of the calibration curve. Such calibration point is indicated by a big circle ② (normally if checked, the point is presented by + sign ⑤).
To omit individual recalibration response from the calculation of calibration curve, deselect the Used check box ③ in the Details of Calibration dialog invoked by 
in the Rec No. column on the respective level.
The calibration point at level 1 consists of overall 4 recalibrations. Only 3 recalibrations were used to compute the calibration point of level 1. Unchecked recalibrations of a level are indicated in the graph as small circles ④. The resulting point for a level with recalibrations is indicated by an asterisk.⑥
Note:
If a recalibration is disabled then this recalibration is not used to compute the calibration curve. Moreover the recalibration at ④ is an outer recalibration and hence the line of scattering does not go through that point.
Caution:
Once a new recalibration is performed the oldest recalibration will be permanently deleted. Meaning that if No. of Points is for example set to 3 and the total number of recalibration is equal to 3, new recalibration (number 4) will delete the oldest one.
