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.
4 Cal Point No. Indicates to which calibration point the parameters below refer,
such as Cal Level and Cal Rate. The selected calibration point cor-
responds to the ACTIVE POINT in ReadIn.
5 Cal Level Enter here the percentage for the calibration point that appears in
Cal Point No..
6 Cal Rate Count rate for the calibration point that appears in Cal Point No..
To delete a calibration point, you have to set both the value in Cal
Level and the associated count rate to 0.
Select ReadIn to read in the count rate. If you already know the
value, you can enter it here.
7 Cal Rate Comp Visible only if Compensation Mode AUTO PRC or AUTO GPC
is selected.
Count rate of the compensation measurement for the calibration
point that appears in Cal Point No..
With ReadIn the compensation count rate is read in at the same
time as the count rate for the level measurement.
8 Cal Rate at Op Visible only if Compensation Mode is not set to OFF.
Shows the count rate calculated under operating conditions,
depending on the respective compensation mode.
9 Sort If the individual calibration points are not entered in the order low
level to high level, then the calibration points can be sorted using
this menu item.
The calibration points must be sorted before enabling Calibrate!
