Select ReadIn BACKGROUND and wait until the measure-

On the following pages you can find detailed calibration instructions.
Always carry out a test calculation after every calibration. This will
ensure that your calibration data are plausible and the detector is
set correctly (see chapter 2.39, page 3-366, Cps Average Mode
and Cps Average Test).
