2Description and Utilization
TSR3 is designed for continuous measuring of radon concentrations in buildings.
Portable probe basis is a measuring chamber with a semiconductor detector. Radon enters the chamber
by diffusion through the input filter on the bottom of probe. The probe measures in autonomous and time
continuous way. It processes results every 4-minute intervals and from this counts short-term moving
average of radon concentration ( 1 hour moving average - average of 15 4-minute process intervals). It also
counts long-term moving average of radon concentration ( 24 hours moving average). The probe saves time
records of these radon concentration values including values of humidity and temperature within its
internal memory (typically at an interval of 1 hour). Next saved value is time record of measuring energy
spectrum (typically at an interval of 12 hours). The probe is random for location in measured place, but
generally it is put on the bottom of the probe. Bottom of the probe cannot be covered. The probe can be
switched on/off by switch. LEDs „STAT“ a „CHRG“ indicate current status of probe see ´Operation manual´
below.
The resulting values can be downloaded continuously during measurement or at once at the end of
measurement. Data from the radon probe can be downloaded to a PC directly via USB interface or
wirelessly via antenna and Central Unit. Central Unit is not included with package of TSR3 and it is sold and
delivered extra ; see http://www.tesla.cz/ .
TSR3 Radon Probe can be operated by these ways:
A) Standalone probe - Thanks to its independent battery power, portable radon measuring probe
supports flexible placing options within monitored structures. Accumulator will last for more than
1 year after full charging. After switching on TSR3 immediately starts measuring and saving results
into internal memory. The resulting values are downloded after end of the measurement by B) or
C) way.

4/9
B) Probe connected via USB –Using usbRADONview app and USB cable is possible to download
results to PC continuously during measurement or at once at the end of measurement. TERAview
application, drivers and user manual is free downloaded on website: http://www.tesla.cz/.
C1) Wireless network for radon measurement - Central Unit supports simultaneous data downloads
from up to 16 probes. All values are saved again into central unit memory. Via connected
computer to Central Unit and TERAview application on PC it is possible to download and process
all data from system and configure whole system. Setting and configuration of TSR3 Radon Probe
and whole system is also managed by TERAview application on PC. TERAview application version
3.11.6 and higher, drivers and user manual with detail configuration description is free
downloaded on website: http://www.tesla.cz/.
In case of time continuous measurement of radon concentration or in case of setting in
regulation system the probe must be placed in radio range of Central Unit. Distance (radio range)
between TSR3 and central unit is up to 600m in open space. In buildings it depends on number of
walls, building material, etc. Strength of radio signals (RSSI) is monitored by Central Unit. If radio
signal strength between individual elements is insufficient, TSR2 radon probe must be inserted or
repeater must be used to extend the signal; see http://www.tesla.cz/
C2) Wireless network for radon regulation –Featuares of system are same as in C1) way. Radon
measuring probes located in building transmit their current radon concentration values to central
unit wirelessly. Central unit analyzes this information and on the basis of measured (set)
concentration level value it sends command to actuator (wireless actuator or actuator in central
unit can be use) which is hardwired with power relay. Power relay switches on a fan which
decreases radon concentration within an area. After decreasing of radon concentration, actuator
receives command to switch off fan. This cycle repeats depending on increasing or decreasing
volume activity of radon in building.

5Operating Instructions
Switching on and off:
The probe measures radon concentration autonomously and communicates in wireless network 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 and doesn´t
communicate in wireless network. 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.
It is possible to download data from probe over USB in both position of switch.
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“
Antenna installation:
Supplied antenna is screwed on antenna connector. When installing antenna, hold antenna by knurled
end.
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 frequency of wireless data downloading from probe. 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 is different according to operation way of radon probe.
If the probe is used for autonomous measurement and data downloading via USB interface then the
setting and configuration are realized by usbRADONview application. UsbRADONview application, drivers
and user manual with detail configuration description are free downloaded on website:
http://www.tesla.cz/.
If the probe is used for wireless measurement and wireless data downloading then setting and
configuration of probe and whole measuring system is realized by Central Unit connected to PC and
TERAview application. Central Unit is not included with package of probe and it is sold and delivered extra;
see http://www.tesla.cz/. TERAview application, drivers and user manual with detail configuration
description are free downloaded on website: http://www.tesla.cz/. For successful probe configuration in
measuring system is essential to know probe radio channel number (communication wireless channel) and
P2P address (identification in wireless net). Both parameters are printed out on probe serial number plate.
Probe radio channel number is possible to change by TERAview application and it must be identical to
central unit radio channel number. P2P address is permanent and it can occur in one big wireless net only
once. Central Unit P2P address can be identical to P2P address of other elements in network.

6Basic 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 three 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) On wireless Central Unit display –Symbol "#" on left edge of display second line means that
accumulator voltage is low.
3) 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:
LED diode ´CHRG´
