Figure 51: AlphaPM connected as front-end to AlphaGUARD
for simultaneous monitoring of radon and its decay products
After connecting the communication cable between AlphaGUARD and the
AlphaPM the progeny meter is synchronized and controlled by the AlphaGUARD
(incl. switched ON/OFF).
- Only the original cable may be used
- The power supply of the AlphPM is assured via its built-
and/or the mains-/ charging unit
-
The sampling time of the AlphaPM has to be set to ”cont_h” for continuous
recording of the radon progeny concentration.
- The quantity "counts" on the AlphaGUARD’s display shows a count rate which
is proportional to the real result of the recent equivalent progeny product
concentra
- The AlphaGUARD solely files count rates in its data storage
- In order to represent the concentration of radon progenies,
respective units, using DataVIEW or DataEXPERT software,
factor for the progenies measurement chann
el needs to be set to 44.4. (see
also operating manual “DataVIEW” or “DataEXPERT”)
