Acquisition 2/5
Display of the current measurement values of the external sensors (2 x TTL signals &
2 x analogue signals). When operating in Radon/Thoron discrimination mode, the
gamma ambient dose rate is shown on page 2 also (DF2000).

The
AlphaGUARD
is equipped with a counter module that allows processing of
externally produced count rates (e.g. TTL signals transmitted by the radon progeny
monitor AlphaPM). The count rate (counts) is displayed in the unit "counts per
minute" (cpm). The maximal count rate of the counter module is 10 kHz resp.
600.000 cpm.

The current measuring values of two additional external sensors can be displayed.
The appearing results depend on the selected configuration of the analog inputs
(see 7.2.8).
The displayed values are based on a cyclic interrogation of the analog inputs in a
2-second cycle.
The display values for the count rate are updated along with each new
measuring cycle.
