Radiation Solutions Inc –Proprietary Page 3 Revision Date: December 11, 2015
2.0 SYSTEM OPERATION
2.1 BATTERIES
a) LOAD BATTERIES in HOLDER - the unit is shipped with
the batteries separate. Remove the Battery Cover by
depressing the Battery Cover Clip at each side. Load the 4
x AA cells with negative at the spring end. Slide the battery
Cover back in place ensuring that the side guides are lined
up –if all OK the Cover should fit smoothly on.
b) LOAD BATTERIES in UNIT –slide the Battery Holder into
the base of the RS-125 with the battery Terminals on the
side of the copper terminals in the unit. (if in incorrectly the
unit will not power on). If all is OK the 2 side mounted
clips should “click” into place to hold the Battery Pack
solidly into the RS-125 unit.
THE RS-125 / 230 ARE SHIPPED WITH CHARGED
BATTERIES. HOWEVER OVER A PERIOD OF TIME THESE BATTERIES WILL DISCHARGE SO
USER ARE ADVISED TO FULLY CHARGE BATTERIES BEFORE USE (4hrs MINIMUM).
2.2 BUTTON
The RS-125 Super-Spec instrument has only ONE control
that is the front panel PUSH-BUTTON referred to as
BUTTON.
This Button is actually mounted on the face of the
instrument but with the normal handle attached,
connection to the Button is via a mechanical link from the
Button on the handle.
The Button has 2 primary actions:
-CLICK –This is a click (SHORT) and release (less
than 1 second button action).
-LONG –This is a click (LONG) and hold action typically held for 3 seconds
with display feedback.
2.3 DISPLAY
The Display is a back lighted LCD display optimized for high
contrast in outdoor conditions. Display Backlighting is required in
low light conditions to make the display readable but this reduces
battery life so to optimize battery life the backlighting automatically
comes on ONLY when required. The Display is used for various
functions and messages.

2.4 POWER ON after BATTERY CHANGE
Press the BUTTON until the unit beeps then release the
BUTTON. The battery change label is shown.
The next display requires battery type selection.
NOTE: The Battery Type selection is required to let the unit know which batteries are used. Battery
discharge rates vary between battery type so that for Low Battery detection it is essential the
unit knows the correct battery selection. Normally RECHARGEABLE batteries are the correct
option for the RS-125 as this is what is supplied with the unit –but the user can select to suit
their requirements.
CAUTION: USERS SHOULD BE CAREFUL NOT TO LOAD non-RECHARGEABLE BATTERIES
SUCH AS ALKALINE, INTO THE UNIT WHEN CHARGING THEM. EVEN THOUGH
THE UNIT IS PROTECTED AGAINST THIS, EVENTUALLY THE ALKALINE
BATTERIES WILL LEAK AND DAMAGE THE INSTRUMENT.
CLICK the BUTTON (short less than 1 second) to move between selections. Once the correct
selection is highlighted hold the Button (LONG-CLICK) until the selection background changes –
release the Button for the correct selection.
The next display is the start-up display and shows for 3 seconds
then changes to the SURVEY display (see Section 2.6 below).
NOTE: The software version will be 5v95 in this case.
2.5 POWER ON normal
Press the BUTTON until the unit beeps and the sign on display is
seen, then release the BUTTON. After 3 seconds the sign on
display changes to the SURVEY DISPLAY.
NOTE: The Version# is the installed software version of
the unit. In any communication with RSI
regarding system performance, it is very helpful
to specify the SERIAL # and the SOFTWARE
VERSION to enable better trouble shooting
support.

2.6 SURVEY DISPLAY
The Survey Display is segmented as shown in the
figure.
Local Time: settable to Local Time in Parameter
Setup –Section 3.1
Battery Status: an Icon that shows current status
of the battery.
ALKALINE batteries
RECHARGEABLE batteries
Total Count: current radiation level in
counts/second units.
Graph: the last 100 readings are shown in graphical form. The right hand reading is the oldest and
the left hand is the latest. This helps the user to look for small changes they might have missed.
2.7 AUDIO
a) INTERNAL - the RS-125 has an audio speaker inside the unit. The audio system is activated when
the radiation level gets above a certain internally computed Audio Threshold. Once the Audio
Threshold is exceeded then the Audio INTENSITY will reflect the incoming count rate to provide a
varying INTENSITY level that relates directly to count rate and therefore local radiation intensity.
In this manner a hands-free survey can be carried out that is usually highly recommended in many
field situations where often the eyes are selecting the terrain so, without proper audio feedback, some
significant count levels could be missed if the eyes are distracted. The Audio system can be fine-
tuned in Parameter setup if required.
b) BLUETOOTH AUDIO
Since the unit has Bluetooth (BT) connectivity, a new feature is the ability to use a BT earphone
system for improved audio in very noisy areas (rivers, rain etc.) See section 3 below to activate the
selected BT earphone system (the RS-125 assumes that VOLUME control is on the earphone as is
normal on most units) –see section 4 for special parameter changes for Audio.
2.8 STABILIZATION
Spectrometer systems like the RS-125 use an integrated SPECTROMETER system to provide data
for analysis of ASSAY results. The accuracy of these results is a function of many items but a very
significant one is spectrometer stability. It is crucial that the system spectrometer maintains a stable
operational mode independent of temperature etc. To provide accurate Assay data the spectrometer
must be stabilized to also give data independent of local
conditions that could affect the data.
To achieve this, the RS-125 has a FULLY AUTOMATIC spectrum
stabilization system integrated inside the unit that uses the low
radiation levels from surrounding geology to perform this analysis.
In principle the system accumulates spectra INTERNALLY while
D-1009 REV 01.05 Status: RELEASED printed 18/12/2015 5:26:09 PM by Radiation Solutions Inc.

RS-125/230 User Manual –Revision 1.05 SYSTEM OPERATION
Radiation Solutions Inc –Proprietary Page 6 Revision Date: December 11, 2015
the system is powered ON and once a high enough level has been
achieved then a complex analysis takes place to determine the
correct spectrum position. This analysis results in an error
measurement that the system uses internally to correct these
effects. Note that this process is completely independent of the
user. Typical Automatic Stabilization takes 5-10 minutes
depending on local conditions.
Once the system is fully stabilized a new icon appears
on the display above the Battery icon to show the analysis is
complete –see figure. The RS-125 can continue to be used in
the SURVEY mode while this fully automatic process is carried out
in the background.
If the system is NOT stabilized and the user attempts an Assay,
an error message appears and the unit beeps 3 times. If the
user ignores this warning, the Assay continues –note that
under these conditions the quality of the Assay data is questionable as system Stabilization is incorrect
so the data could be roughly OK if stab is close but really bad data if Stab is significantly in error. The
stab status is shown on the data retrieved to the PC for data verification.
In previous software versions, Stabilization was inhibited during Assay to minimize data errors.
However if users are taking repeated Assays this means that Stabilization will be suspended for a long
period of time and during this period the system could drift causing significant data errors.
To prevent this happening in Ver. 5v95 the Stabilization accumulation of data is NOT interrupted by
the Assay process.
In fact an auto correction is implemented so that if at the end of Assay a Gain correction is required,
the system automatically computes the potential Gain error and corrects the data to minimize system
errors.
In addition the unit beeps every time it stabilizes as a reminder to the user that all is well. This can be
inhibited if judged to be a problem –contact RSI. See Appendix Z for Contact Information.
2.9 ACTION
The RS-125 only has one BUTTON as noted above. To achieve
the required system functions CLICK (short) and a Menu
appears. The user navigates up and down this menu using
CLICK (short) and the highlighting moves with the selection.
Once the selection is made, hold the Button until the
background changes from Dark to Light (typically 2-3 secs) then
release the Button to make the selection.
Selections:
a) Assay –activates the ASSAY capability of the system (see Section 2.10 below)
b) Reacquire bg –rests system background (see Section 2.11 below)
c) Start recording –activates the RECORDING capability of the system (see Section 2.12 below)
d) Configuration –permits parameter changes (in firmware versions before ver. 5.19, parameter
selection was accessed on power up but v5.19 has made setup easier) - (see Chapter 3.0 below)
e) Continue survey –this selection returns to the previous SURVEY display with NO change in
background setup levels.

2.10 ASSAY
NOTE: THE DISPLAY MUST SHOW THE STAB
ICON BEFORE THE ASSAY DATA IS
VALID.
If ASSAY is attempted with incorrect Stabilization an error
message will appear on the display and the unit will beep 5
times. Correct action is to press the button once to
terminate the ASSAY and wait until the unit is stabilized
(normally 2-5 mins max).
When the ASSAY selection is made the ASSAY mode starts
and a new display is seen
Meas Time –When the sample starts, a preset Sample Time
parameter shows the sample time on the right
and a count up timer showing the sample
progress on the left.
Once the first 30 secs sample point is reached an Assay result
is shown. Each additional 30 secs the Assay data is
recomputed and updated on the display.
For best accuracy the full count period should be permitted.
However in very anomalous areas sample times as low as 60
seconds give very good data due to the large detector size.
Guidelines are:
60 secs –anomalous area –low quality data is fine –
fast sampling is required to get maximum data
for an area in a short period of time
120 secs –(DEFAULT) anomalous area –medium quality data is fine –fast sampling is
required to get maximum data for an area in a short period of time
180 secs –medium anomalous area –good quality data is required
240 secs –medium to low anomalous area –high quality data is required
300-1800 secs –low anomalous area –maximum quality data is required
Note if the sample period is set ABOVE 999 secs then for display limitation reason, the “Meas
time” is shown as a % of completion starting at 0.1%.
FOR EASE OF USE THE SAMPLE PERIOD IS NORMALLY
SET TO 120 secs AS THIS VALUE GIVES GOOD QUALITY
DATA IN MOST CONDITIONS. See Chapter(s) 3 and 4 to
change to suit users requirements.
At the end of the preset Assay period the sample stops and the
audio continuously beeps to advise user of the end of sample.
The user takes the unit and presses the Button to stop the
audio and inspect the display results. Note the display top label
now shows “ASSAY RESULTS”.
Note that the Kdata is shown in %and the U and Th data in
ppm (parts/million –N.B. ppm/10,000=%). The Total Count is
usually shown in DOSE units (Sv/ Gy, R) to give users an idea
of the relevant Dose information and can be used as an overall
indication of radiation intensity.

RS-125/230 User Manual –Revision 1.05 SYSTEM OPERATION
Radiation Solutions Inc –Proprietary Page 8 Revision Date: December 11, 2015
The user can then view/note these results then press the BUTTON again and the display shows:
The user has approximately 3 secs to note the TIME or the Spectrum # to enable them to relate the
stored data to the actual sample location when data is retrieved from the unit. Alternatively the user
can note the TIME on the RS125 display BEFORE the sample is started as perhaps an easier way to
record the data results relationship to sample location. The data is stored in system memory and can
be retrieved later (see Section 4). NOTE: when the unit is initially setup the first spectrum is #0, after
that they increment 1, 2, 3 etc. Even when data is erased this continues so if the last spectrum of the
day was #46 then the first spectrum of the next day could be #47 the next #48 etc. This number
continues to increment indefinitely so identical sample #’s cannot occur. This method of “universal
spectrum numbering” helps in minimizing data confusion.
SHORTEN ASSAY PERIOD
At any time AFTER THE FIRST 30 SECS - the user can stop
the Assay progress by a short CLICK of the Button –the display
then shows the Assay Results with the time shown at whatever it
stopped at. This is NOT recommended as the quality of the data
depends a lot on the sample time.
Selecting a fixed sample time (usually 120 seconds) and
ensuring all users wait for full sample completion, is a sensible
way to maintain overall data quality.
DATA MEMORY LIMITS: Refer to section 4 (MEMORY) to determine system memory limitations
and selections. The user is recommended to download data each day to prevent data loss.
GPS with ASSAY
If a GPS unit is configured (linked) to the RS unit then GPS location data is recorded at the end of the
Assay period. To conserve GPS battery power it is only necessary for the GPS to be powered ON for
a short time during the Assay sample period. To assess this –at the start of Assay power the GPS to
ON and there should be a flashing cross-hair below the battery icon. Once the GPS has a good lock
on satellite data, the cross-hair goes steady. As soon as this steady-state is seen the GPS
coordinated have been transmitted to the RS unit so the GPS can now be powered OFF. Of course
the GPS can stay on at all times if battery conservation is not a problem.
SPECIAL FUNCTIONS –see Section 4.5.5 Settings - Measurement for special Assay actions.
2.11 Reacquire Bg
When in the SURVEY mode of operation, the AUDIO
THRESHOLD is set using a preset parameter –usually 1 Sigma
for Geophysical application. When the unit is powered on, after
internal checks the first 3 x 1 second samples are averaged and
the Audio Threshold computed from this average –then the
Audio is enabled. If the count level exceeds this threshold the
audio sounds as described above. However in many areas the
local background changes and this causes threshold problems.
As an example if the local background level was 100 cps then at
1 Sigma the Audio Threshold = 110 cps (100 + 1 Sigma). So if
the count rate goes above 110 cps the audio will sound.
However if the local Background increases substantially to 300
cps then the audio will be on continuously and the audio will not
seem as sensitive to small local changes. Similarly if the local
Background goes down to 50 cps then the local radiation would

Radiation Solutions Inc –Proprietary Page 9 Revision Date: December 11, 2015
have to increase very substantially before the audio sounds –thus effectively desensitizing the audio
system.
To overcome this “problem” AT ANY TIME the user can briefly touch the BUTTON and select the
Reacquire bg selection. Then the system will return to the SURVEY display and the system will
automatically recompute the Audio Threshold and the message “UPDATING BACKGROUND” will be
seen on the display for the 3 seconds of the update. This means the user can “retune” the Audio
Threshold at any time thus keeping the audio threshold optimized.
2.12 Start RECORDING
The RS-125/230 now has a RECORDING capability that permits
automatic recording of TOTAL COUNT data and/or ASSAY
RESULTS into memory to permit line profiles etc. In addition an
external GPS unit can be interfaced directly into the unit via the
Bluetooth connection and the GPS data integrated directly into
the internally stored data memory.
NOTE:MEMORY –system memory is allocated to suit users
requirements. (See Section 4.5.5.3 for details and
changes).
a) RECORDING WITH GPS
The system has been developed to work with Bluetooth (BT) GPS and communicates data directly to
the RS-125/230 unit(s). However the GPS output data stream NMEA (GGA format) is common to all
units so other GPS units should also work.
GPS INITIALIZATION
Setup the GPS recording link as described below in Section 3. Once the GPS is activated (linked) to
the RS-125/230, data recording can start.
From the Main Menu select “Start recording” and new icons appear on the
display as shown in the figure.
The “R” symbol shows that recording is ON and the cross-hairs show the GPS
connection. If the cross-hair symbol is flashing this means that the GPS has not
found a good satellite lock so data recorded in the system for Lat/Long are
ZERO. When the GPS acquires satellites the cross-hair is solid showing proper
location data is being recorded.
NOTE: When the GPS is activated it does nothing until the START RECORDING selection is made.
Then the unit starts to automatically acquire satellites to get a good lock. It is very common that
it takes 5-10 minutes to get a good lock with as many satellites as are available (this is the
equivalent of a cold start. Once it has found ALL the satellites available it only needs 3 to get a
good position. This means that once it has got all the satellites available it can continue to give
good data even in areas where many satellites are lost.
c) WITHOUT GPS
If no GPS is connected or activated Profile recording can still occur. From the
Main Menu select “Start recording” and new icons appear on the display as
shown in the figure. The “R” symbol shows that recording is ON and the flashing
GPS cross-hairs still appears but may be ignored.
c) STOP RECORDING
From the Main Menu select “Stop recording” and the record icon will disappear,
the flashing GPS cross-hairs still appear but may be ignored.

2.13 DATA RECORDING GENERAL
The data recording action, when the symbol is shown means that the selected data is being
recorded.
Section 2.13.a), b), & c) below permits the user to select whether to record TOTAL COUNT data only,
ASSAY RESULTS only or both.
a) TOTAL COUNT data only
Set parameters as required:
RECORD TYPE = Total only
Total scan period = 1- 20 secs (e.g.1 sec)
MEMORY allocation as in section 4, selected to
suit recording needs.
When START RECORDING is selected then Total Count data is stored in memory at the selected rate
(Total scan period) of 1 sample/sec (or as selected).
The data is stored in 30 sample data blocks. If an external GPS is integrated, the GPS data is stored
every 30 samples –if no GPS is connected the GPS data is stored as zeros.
Some users want to record GPS data at a faster data rate. This can be done but some memory gets
sacrificed –see Appendix B.
When data recording is complete press the Button to see the menu and select Recording OFF to
terminate recording.
RS-Analyst is used to retrieve this profile data see section 4 for more details.
b) ASSAY RESULTS data only
User must select:
RECORD TYPE = Assay only
Assay scan period = 30-1800 secs (e.g. 30 sec)
MEMORY allocation –as described in section 4.9
Parameter setup can be done manually as described in Chapter 3.0 but it is much easier to do
via PC connection as shown in Chapter 4.0.
When START RECORDING is selected then Assay Results only (no spectra) data is going into
memory at the selected rate of 30 secs/sample.
The data is stored in a txt file, if an external GPS is integrated the GPS data is also stored –if no GPS
is connected the GPS data is stored as zeros.
When data recording is complete press the Button to see the menu and select Recording OFF to
terminate recording.
RS-Analyst is used to retrieve this profile data as shown below in a space delimited file that can be
read into Excel as required –see Chapter 4.0 for more details.
c) TOTAL + ASSAY data
In this case BOTH the Total Count + GPS data and the Assay Results + GPS data are stored in their
appropriate memory locations and can be retrieved as described in Appendix A.

NOTE: Customers Recording Data in OnTheFly Assay mode may find that if the device had been
previously setup for Record Mode that the sequential order or chronological numbering for
saved files will be affected, as the device is also storing data for OnTheFly storage. It appears
that the sequential numbering is skipping as the device is storing data on the fly. Each
Record assay and OnTheFly assay is assigned a unique ID. From affected customer`s data it
appears that assays were being saved while the “OnTheFly” option was started. In this case
the unit would assign an ID to the Manual (Record) assay and skip the OnTheFly assay, thus
resulting in non-sequential ID numbering. To prove this is happening compare the time
stamps of the exported “Manual assay”data and the “OnTheFly assay” data. When you
export the data the “OnTheFly assays” will be the ones that have a blank space in the total
column while the Manual assays will contain all the data.
2.14 POWER OFF
To power OFF the unit, press and hold the BUTTON and the unit powers OFF. The display shows a
countdown “TURNING OFF 3”, “TURNING OFF 2”, “TURNING OFF 1” then the unit finally powers off.
Sometimes this countdown sequence can take a few seconds before initiating if the unit is “busy” but
typically no more than 5 seconds before the countdown sequence starts. If the BUTTON is released
at any time before power OFF, the unit will continue to function.
2.15 LOW BATTERY
If the Batteries are getting low, an audio beep prompts the user to view the display. If the Battery icon
shows very little battery left the battery pack should be changed. RSI recommends that a spare
Battery Pack is carried at all times to prevent field problems as changing is a few seconds task with
NO loss of stored data.
Two battery modules are supplied with each unit.

b. DISPLAY
i. CONTRAST sets the Display CONTRAST. Selections are -3,
-2, -1, 0, 1, 2, 3. -3 to -1 lightens the display, +1 to +3 darkens
it. Normally “0” is a good average selection. CLICK to select
the right setting then LONG-CLICK to set this selection.
ii. BACKLIGHT –this sets the Display BACKLIGHT.. Selections
are AUTO, ON, OFF.
AUTO = the system automatically selects the required Backlighting using a light sensor to set the
required level. This is the best selection but in dark shadow areas the Backlighting will come
ON to make the display more visible. While often this is a required feature the downside of
this is a significant reduction in battery life by typically 40% if the Backlighting is ON all the
time.
ON = overrides the light sensor and sets the Backlighting ON all the time.
OFF = sets the Backlight permanently Off to conserve battery life.
iii. GO BACK –return to the Configuration menu.
c. AUDIO
i. VOLUME - this enables or disables the audio survey system.
Selections are ON, OFF
ON = Audio is enabled
OFF = Audio is disabled
For Geophysical applications set to ON as Audio Survey is an
essential operational requirement, the OFF mode is used for special applications
ii. FILTER LENGTH –this sets the filtering parameters to optimize the audio system response for
different applications. Selections are 1-10 and indicate the number of 50mS samples are
averaged.
1= shortest filter thus the fastest audio response
10 = longest filter giving the slowest response
SHORT filters give fast response but don’t give such a “smooth” response to a slowly increasing
field.
LONG filters give a very smooth “even” response for a slowly moving field but tend to minimize
short term local effects
