2 Background
The term background refers to the background radiation which is
present in the environment. The background radiation has to be
measured so that the detector can correctly compensate for the
decay of the radiation source.

Select ReadIn to read in the count rate for the background
radiation. If you already know the value, you can enter it here.
3 Background Comp
 Visible only if Compensation Mode is set to AUTO GPC .
The Background Comp is the background radiation which is pres-
ent in the environment and is measured by the compensation
detector.
With ReadIn BACKGROUND the count rate for background comp
is automatically read in.
If you already know the value, you can enter it here.

Indicates to which calibration point the parameters below refer,
such as
Cal Level and Cal Rate . The selected calibration point cor-
