1Introduction
This document describes technical specifications and user operation of the TSR2 Wireless Radon Probe.
Product was developed and manufactured in the Czech Republic. All rights reserved TESLA. Offer or
delivery of products or services related to the product does not include transfer of ownership rights.
Before using the product, please read this manual carefully and understand all operating and safety
precautions. Compliance with operational and safety precaution can prevent from damage to equipment or
injuries to personnel. Operating and safety instructions in the document are marked as follows:
Attention! This formatted text indicates the operating and safety instructions.
The product may only be used in the specified manner and for its intended purpose. The product may
be provided to third persons along with this documentation only.
2Description and Utilization
TSR2 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 at given intervals (default 4-minute intervals) and it counts moving
average of radon concentration value at an interval of 1 hour (default moving average of 15 4-minute
process intervals). It also counts moving average of radon concentration value at an interval of 24 hours.
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 resulting values can be downloaded
continuously during measurement or at once at the end of measurement.
Attention! For downloading of measured values from probe it is essential to have wireless Central Unit
in system; see http://www.tesla.cz/ . Central Unit is not included with package of TSR2 and it is sold and
delivered extra.
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 TSR2 Wireless Radon Probe and whole system is also managed by
TERAview application on PC.
TERAview application, drivers and user manual with detail configuration description is free downloaded
on website: http://www.tesla.cz/.
Thanks to its independent battery power, portable radon measuring probe supports flexible placing
options within monitored structures. Battery will last for more than 1 year.

Probe is supplied by AA non-rechargeable replaceable 3.6V lithium battery or by power adapter 230V;
see paragraph ´Accessories´. After battery insertion TSR2 immediately starts to run time-continuous
measurement.
TSR2 Wireless Radon Probe can be used in these systems:
A) TERA System for Radon Concentration Measurement (Figure 1)
B) TERA System for Regulating Radon Concentrations (Figure 2)

Figure 2 - TSR2 Wireless Radon Probe in TERA System for Regulating Radon Concentrations

Regulating system diagram description - 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 wireless command to actuator 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.
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. 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 TSR2 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.
Attention! 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/

5Operating Instructions
Switching on:
To switch the probe on, remove protective band under the cover and then reinstall the cover. Reverse the
procedure to switch device off or for battery replacement. (Switching the device off is appropriate only
when unused for long periods of time.)
Antenna installation:
Supplied antenna is screwed on antenna connector. When installing antenna, hold antenna by knurled
end.
Configuration:
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 TSR2 and it is sold and delivered
extra; see http://www.tesla.cz/.
TERAview application, drivers and user manual with detail configuration description is free downloaded
on website: http://www.tesla.cz/ .
For successful probe configuration in measuring system it 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
Battery replacement:
Current battery charge status of probe can be monitored wirelessly by Central Unit (see ´Operating
instruction/Configuration´). In case of low battery capacity Central Unit dipslays warning message. Twist
battery cover to the left to remove discharged battery and replace it with appropriate type (see ´Product
Specification´). Batteries can be ordered from TESLA manufacturer or distributor (see ´Accessories´).
Positive pole pointing up and inserted directly under the battery cover. Close the battery by pushing and
turning the battery cover.
Replacing of particulate filter:
In extremely dusty environments congestion in the particulate filter, which is part of the radon probe
bottom, can occur. Congestion of the particulate filter by dust particles prevent from optimal diffusion of
measured gas to detector and thus distort measurement results.
By loosening and unscrewing inner ring nuts on the bottom of the probe perforated black plastic cover,
metal grille and white particulate filter get released. Only these three circular elements can be taken away
from the bottom of the probe. Replace the particulate filter, which is available from TESLA manufacturer or
distributor and return three circular elements in reverse order to the bottom of probe. Arrange assembly by
screwing the inner ring nut.
