General Count Rate Measurements (cps; cpm)

These are the most general measurement units (cps = counts per
second; cpm = counts per minute). The displayed value is inde-
pendent of any specific calibration factor which may not be avail-
able for a contamination with unknown nuclides. Both gross
count measurements and net count measurements can be per-
formed. The selection can be performed by the PC-settings or in
the menu <Background> by tagging <Ratem. netto> and/or
<Scaler netto>. The background count rate for these netto meas-
urements can be determined via a background measurement in the
menu <Background>. The derived background count rate can be
stored and is used for all following net measurements. This value
is always displayed in the top section of the LCD in order to re-
mind the user that the measured value has been corrected by that
particular count rate value.
