DATAQA - data quality
Short
definition
Description of quality parameter
Recommendation
LOLIM
Measuring value was outside
lower measuring range
(< 2 Bq/m³) or Rn-error was higher
than respective Rn-value
(AlphaGUARD display shows the
radon value preset with "<"
-
UPLIM
Measuring value exceeded the
upper measuring range
(> 2 MBq/m³) (> 50 KBq/m³ for
D50)
-
PREA
Automatic determination of the
present base line of the
preamplifier offset has been
effected (typical for each
hundredth measuring cycle, if Rn-
concentration: 100 - 10 000
Bq/m³, temperature: 10 - 30°C, air
humidity: < 80 % rH and other
parameters of the DATAQA
inconspicuous)
-
QASPE
Alpha spectra shows irregular
form
Contact your local Bertin
distributor in case of
increased incidence
QANOI
Inadmissible noise level
diagnosed in the alpha spectra
Contact your local Bertin
distributor in case of
increased incidence
DEWPT
Ambient conditions were in the
dew point range, e.g. potential
danger of condensation for the
measuring electronics
