Read in count rate A process that is started by the user in order to determine the
average value of the count rate at the respective level. This
count rate is needed to calibrate the measurement. The count
rate is averaged over a certain time (standard 60 s) to exclude
statistical and process-immanent fluctuations.
Factory setting All parameters have been preset by the manufacturer using
standard values. In most cases this simplifies calibration of the
instrument significantly. Despite factory setting, calibration
al-
ways has to be performed.
