analyses and stores background counts for each detector. All
counts are corrected to compensate for the “dead-time” of the
electronics. In measurement mode, background is
automatically subtracted and the result clearly shown by
audible and visual indicators. Options include a “Residual
Contamination” check which can be performed after an alarm,
if required and an “Auto Recount” can be performed if the
initial measurement produced an alarm condition. Two-door
variants can be programmed to lock after alarms if required.
The standard SAM12 can have the following options in any
