2Description and Utilization
TSR3D is designed for continuous measuring of radon concentrations in buildings and results are also
shown on display.
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). All results are shown on display as well see paragraph
´Display Operation´.
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 is downloaded to a PC directly via USB interface. Capacity of
internal memory is almost unlimited.

4/10
TSR4M 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 TSR4M immediately starts measuring and saving
results into internal memory. The resulting values are downloaded after end of the measurement
by B) way.
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.

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.
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:

Description
Green blink 3x

Green blink after 5s
Radon probe measures and works correctly
Yellow blink 3x
Radon probe has just been turned off.
Green / Yellow
blink after 5s
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:
http://www.tesla.cz/en/ke-stazeni/.
6Display Operation
Built-in display can continuous show measured result and basic parameters of probe. By reason of
power saving the display isnt switched on permanently but it is switched on by pushing of button below
display. By next pushing of button is changed screen on another in cyclic order. Approximately after 1
minute without pushing of the button the display is automatically switched off.

7/10
After first pushing of button from switched off display status is shown intro screen. There is shown basic
information about probe as is version of firmware, serial number and status measurement running ON/OFF.
Go on basic data screen is possible by three ways:
-by next pushing of button on intro screen
-automatically after 5 seconds from intro screen
-directly from switched off display by pushing of button for longer than 1 second
Changing of three data screens is cyclic without intro screen and is possible to make by pushing of
button. Data screens are on following pictures.
Basic data screen firstly shows 1 hour moving average of radon concentration in Bq/m3. Time behaviour
of radon concentration is graphical shows in array of 128 x 24 pixels. Every columm means single data

8/10
record. So for example if data record time interval is 30 minutes the graph shows time behaviour of radon
concentration for last 64 hours.
Second graph shows current energy spectrum in array of 96 x 24 pixels and its parameters. Energy
spectrum is divide into 96 interval and radon concentration is calculated from intervals d1-d2 (RaA) or from
d1-d3 (RaA+RaC). Discriminations d1, d2, d3 are shows below graphs as well.
Numbers of impulses in discrimination intervals are counted during spectra record time interval (Trec)
or till then if one of particular intervals reaches 255 impulses.
Parameters on third data screen are especially service data but record time intervals are useful.
Notice: By display and button isnt possible to setup of probe. For setting of probe parameters is
neccessary to used the PC software application usbRADONview.
7Basic 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 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:
