Background subtraction
Enhances the detectability of very low activities.
DPM
calculation
With the entry of individual values of efficiency can be
performed automatically.
High
count rates
For high count rates up to 200,000 cps the system is
equipped with a dead time correction.
Print
out
All parameters as well as results can be obtained via RS
232C port.
