Operating Instructions
Switching on and off:
The probe measures radon concentration autonomously only if the switch is in position „I“( switch on).
The switching on is signalized by LED diode „STAT“ according chart below.
If the switch is in position „0“ (switch off) the probe doesn´t measure radon concentration. In switching
off mode the probe only keeps running real time for correct date and time of records in case of switch it on
again. By switching off the probe doesn´t lose previous records of measurement. The switching on is
signalized by LED diode „STAT“ according chart below.
Download data from probe over USB is possible only if switch is in position „I“( switch on).
LED diode „STAT“:
It signalizes status radon probe according to following chart:

Radon probe measures but troubles are occur. – especially low capacity of
accumulator. Warnings and errors are shown in PC application.
No light, No blinking
Radon probe doesn´t measure or accumulator is empty or device is damaged.
Charging process of accumulator is described in chapter „Basic Maintenance/
Accumulator charging“
Power supply:
According to operation method the radon probe can be supplied:
1)
By internal accumulator for portable use – Radon probe includes internal accumulator which is
able to ensure autonomous operation of probe for more than 12 months without charging.
Depends on climatic condition of probe use. Accumulator is charged with USB port and provided
USB cable. The USB cable is possible to connect to PC or to delivered power adapter. Status of
accumulator and charging process are described in paragraph ´Basic Maintenance/Accumulator
charging´
2)
By mains power supply 230V/50Hz for stationary use – Radon probe is permanently supplied by
delivered power adapter. Power adapter is connected to probe via provided USB cable. In case of
blackout internal accumulator ensures UPS function.
Configuration:
Setting and configuration are realized by usbRADONview application. UsbRADONview application,
drivers and user manual with detail configuration description are free downloaded on website:

Basic Maintenance
Accumulator charging:
During portable use of radon probe is essential to monitor state of internal accumulator and recharge it if
necessary. If accumulator is discharged the probe automatically turns off. The probe is switched on again
powering USB port.
Current state of accumulator can be determined in two ways:
1) By LED diode ´STAT´ - If LED starts blinking in green-yellow color it indicates that system is working
incorrectly and one of main case is low voltage of accumulator. (see paragraph “Operation Manual /
LED diode “STAT””)
.
2) In TERAview and usbRADONview application - where you can check current accumulator voltage.
Voltage should not fall below 3.5 V, in limit conditions falls below 3.3V.
Accumulator is charged via USB port using supplied USB cable. USB cable can be connected to PC or to
supplied power adapter. Connect USB cable with power to USB port of probe. LED diode ´CHRG´ next to
USB port of probe indicates charging status according to following chart:
