RADON-SCOUT

If the cell voltage drops further below 0.95 Volts, the measurement is stopped automatically
and the device enters into the stand-by modus. Discharged batteries are indicated by the red
LED, flashing each four seconds.
Start of a measurement
Setting the toggle switch to the right starts the measurement of the Radon activity
concentration in the ambient air. Older data will remain in the memory and can transferred
later together with the new one.
RADON-SCOUT only
In case that the switch is already set to the position "RUN" during replacement of discharged
batteries, the measurement will be started immediately. Please set the real time clock and
restart the measurement once again. The LED will flash in green for about half a second,
then LED will flash one or three times each four seconds dependent on selected integration
interval (one flash = three hours, flashing three times = 1 hour).
RADON-SCOUT-PLUS only
If the toggle switch is already in „RUN" position after replacing the battery, the display will
show a request to set the real time clock of the instrument by the PC software.
To start the acquisition, the switch has to be set firstly to "STOP" and then to "RUN" position.
The green LED lights for a short time and blinks each 4 Seconds during acquisition.
After starting, the remaining time to finish the first integration interval (until the first value can
be calculated) is displayed.
As soon as the results of the first integration interval are available, the display switches over
automatically between two display pages (each Minute). The first page contains the actual
value for Radon with statistical 1-Sigma error as well as the sensor readings (T, rH, p),
battery voltage and time stamp. The second page shows the Radon average since the last
start of an acquisition, the time of the start, the time period from start (used for averaging)
and the number acquired records.
All results are stated in the physical units as selected by software (SI or US style).
Interruption of a measurement
A recent measurement series may be interrupted by switching the toggle switch to the
position "STOP", assumed that it is not locked by the software. The Radon-Scout will enter
the "STOP" modus immediately without finishing the recent integration interval.
The RADON-SCOUT PLUS will show "Radon-Scout PLUS"
To perform a measurement
Preparation
Prior to each new measurement campaign, the status and type of the batteries should be
checked to avoid a loss of data with respect to a interruption of the analysis. In case that the
cells had been changed after you adjusted the real-time clock the last time – adjust the timer
again to ensure a reliable time regime!
Selection of the right location for exposure
The Radon-Scout was designed for stationary monitoring. Strong vibration, movement or
mechanical shocks can disturb the analysis. This interference will be detected and
