When I do calibrations I want to keep the old calibration history so I do not want to delete the old calibration points. Hence when processing a new calibration run I leave the "run type" blank in the "injection list". At this stage the I uncheck the "uncheck" the "use" box, save the method and update the master method.
Any subsequent runs will have all the calibration points included, even the previously unchecked ones?
I am obviously not understanding this process. see attached pdf.
