A series of measurements from an insulating powder is used to illustrate charge compensation during measurements and how charge correction is performed in CasaXPS. The energy scale is calibrated by using the binding energy for an O 1s peak to establish the binding energy scale for five measurements from the same material. An example of manually calibrating a measurement is illustrated within the video as well as a demonstration of how energy calibration can be performed automatically for a set of measurements.
