The calibration submenu serves for the adaptation of the measurement system to
the relevant environmental conditions like e.g. the thickness of the mould, the ac-
tual radiation activity or the adaptation of the background radiation (background
level). The background radiation can vary from location to location.
You can also carry out a multi-point calibration. This is indispensable for operation
with an activity-optimised radiation source (AOS) for factoring in the varying rises
of the calibration profile between 0% - 50% and 50% - 100%, also leading to in-
creased accuracy with commonly designed sources of radiation.
