The Readsensor can by used without PC and with PC.
To move from the use with or without PC you have to change the electronic key
(photo nb 1) that is located just close to the printer paper under the bleu cap (photo
nb 2). WHEN YOU CHANGE THE KEY PLEASE SWITCH-OFF THE READER.
There are 2 keys provided with the Readsensor: The first named “anyCheckValues”
is for the use of the paper printer and the other key “camera” allows connexion of the
readsensor to your PC. Both keys are placed into the small plastic pouch.
For using the paper printer, proceed as follow:
1. connect the small keyboard (photo nb 3).
2. connect to power supply (photo nb 3).
3. Switch-on (rear panel, photo 3) and after 2 sec the system ask for the name of
operator. Introduce the name with the keyboard and press ENTER with the
keyboard.
4. The system request to have a BLANK dipstick. Take the tray and deposit a
blank dipstick into the furrow of the tray. The dipstick must facing out of the
reader. The sample pad of the dipstick must be visible outside the reader
when the dipstick is introduced. If the dipstick is in the wrong position, turn it
for 180° like in the photo nb 4. IT IS VERY IMPORTANT TO INTRODUCE
THE DIPSTICK IN THE RIGHT WAY THAT IS THE SAMPLE PAD ALWAYS
OUTSIDE (facing out).
5. The system make the blank calibration automatically and than ask for the type
of test you want to run. Switch on the black button from the reader to indicate
the type of test and for running a Twinsensor, switch on the first black button
just under TWIN.
6. The reader request to have a CHECK dipstick and you have to introduce the
check lot number with the keyboard, so please type 051612 and ENTER.
7. Enter the EXP date that is 16/12/2006 and ENTER, note that the year should
be in 4 numbers.
8. The reader ask you to pull the BLANK dipstick out and to insert a TWIN
CHECK dipstick in. Remember the way to insert always the sample pad
outside the reader (photo nb 4).
9. Now the system print a small ticket indicating that the blank and check have
been done correctly. The reader is now free for any additional measurements.
To continue please switch on “Measure” the first black button again.
10. Tell what you want to do for instance switch on START, again the first button.
11. Tell the type of test: again the first black for Twinsensor reading.
12. Inter the test code that is BT00640 ENTER with the keyboard.
13. Enter the LOT number in 6 numbers like 061303 ENTER.
14. Enter the EXP date like for the check EXP date : 13/03/2007 ENTER
15. Enter the SAMPLE ID: like MILK Nb1 ENTER
16. The reader ask you to pull the dipstick out, until you see the indication “Insert
a dipstick” and than introduce it in the right position like on the photo nb 4.
Than the system display and print the paper.

Installation
Insert the CD and go to READSENSOR SOFTWARE 702, and start SETUP and
follow the instructions to install the Rapid Designer program to your computer.
Connect the reader through its serial line to the serial port of your computer.
Start the Rapid Designer program and choose the proper serial port using the Ports
section of the window.
Switch the reader on.
The Rapid Designer program
The program displays the image of the reader, together with the curve(s) which is
(are) calculated based on it.
The curves are the integration of the pixel values in vertical direction. Only those
pixels are used (and integrated) which are between the two horizontal red lines. So
only that part of the image is used for any further processing (curve calculation, data
saving) which are between the lines. The test and control line related data are
displayed on the bottom side of the window. (position, tolerance, area, amplitude)
1. Change the test type
The radio buttons at the right bottom side of the Rapid Designer window could be
used to choose the required type of test. When one of these buttons is clicked the
reading will restart.
2. Taking white image (blank calibration)
Take a ”blank” image of the unused dipstick first. The Normalized values are
calculated based on it.
Insert the unused dipstick into the reader. Wait while the full image is displayed and
set the proper lighting. It can be done by clicking to the Increase light or Decrease
light and displaying the white, blank curve (can be viewed by choosing white in the
View section). The current light setting is displayed in the status row of the window
(bottom). (e.g.: Lighting: 5)
The white curve should not reach the top of the diagram (because it means that
saturation). Store the white curve by clicking the Blank calibration button on the
bottom of the window. The white image can be displayed any time by choosing
White in the Picture section.
Set also the start line, where the picture will start. It can be done by clicking the
Increase start ccd line and Decrease start ccd line, next to the display field.
Store the lighting and start line by clicking the Save lighting and lines button.
3. Taking and analyzing images
The program refreshes the display and displays the actual image of the reader
automatically if the Actual is set in the Picture section. It can be stopped and
restarted by clicking on the Stop and Start buttons upper side of the window.

Teach the line position to the Reader:
Before doing any changes, please note the setting value of “position” and “tolerance”
in order ot re-set whenever you want.
Line Position and Tolerance are set into the system but you can teach the line
position at any time as follow:
Insert a used strip to the reader, and wait while the full image is displayed.
1. Select that line which would be set. It could be done by click on the little circle
button in the proper line section on the bottom of the window. (Test line 2,
Control line, Test line 1)
2. Clicking the left mouse button at the desired line position on the image of the
strip (upper picture)
3. The line positions could be set in the other way. Write the desired line position
in the desired line section (Test line 2, Control line, Test line 1) and press
Enter.
Set the line tolerances:
Write the desired line tolerance in the desired line section (Test line 2, Control line,
Test line 1) and press Enter.
When the position and the tolerance of the lines is set they could be saved by
clicking the Save lighting and lines button.
The curves are displayed on the diagram section of the window. The following
curves can be calculated and displayed:
White: the stored white/blank curve is displayed
Actual: the curve of the actual image
Normalized = (Actual/White)*100
If the Clear (in the bottom left corner) function is set, only the last selected curve is
displayed. If it is not set, all the curves are displayed.
4. Save/Load data
Use the Load and Save data buttons on the upper left corner of the window. Save
data button will store the picture of the cassette and the actual light and line settings.
The Load button will display these data (picture, light and line settings).
It is practical if you use the Continuous saving button (this button is also in the upper
left corner) in the Rapid Designer program to save the pictures and data.
1. Firstly write the number that how many measurement you would like to save
to the little window at the right side of Continuous saving button.
2. Then click the Continuous saving button which will stay pressed state.
3. The program will only ask for the file name once, and then save the
measurement serially while the set number become zero. So the program will
take as many series measurement as you set in the little window on right of
the Continuous saving button.
4. The program will save your data with the previous name but an increasing
number will be added to the file name. (i.e.: sample_006.rap)
5. When this number becomes zero the continuous saving button will be
unpressed state automatically but the series measurement could be stopped
by click the Continuous saving button.

1 Introduction
Readsensor is a reflectance photometer designed to read and evaluate the
appropriate Twinsensor (or Tetrasensor) dipsticks. The Twinsensor was designed for
the safe and reliable detection of ß-lactams and tetracyclines compounds in milk with
high sensitivity, (only tetracycline for the Tetrasensor), which is a key feature under
the requirements of today’s high standards in quality control systems. The
Readsensor reads the dipsticks under standardized conditions, saves the results to
memory and outputs them via its own inbuilt printer and/or serial (RS 232) interface.
This instrument is designed for In Vitro Diagnostic (IVD) use for professional use
only.
BIOHAZARD: Treat all samples of animal origin as being potentially infectious.
Always observe good laboratory practice.
Using Readsensor eliminates factors known to affect visual evaluation of test
Dipsticks, such as:
• Objective readings especially in visually doubtful cases
• Different reaction time for the Dipsticks
• Automatic documentation for quality assurance purposes
• Clerical errors
2 System description
2.1 Twinsensor or Tetrasensor dipsticks.
Twinsensor (or Tetrasensor) dipsticks for the qualitative detection of total ß-lactams
and tetracycline (or tetracycline) in food products. The Readsensor works only with
these kind of dipsticks.
For professional use only.
INTENDED USE
The Twinsensor dipsticks are rapid chromatographic immunoassay for qualitative
detection of Total ß-lactams and tetracycline in food products.
The Readsensor system will only indicates qualitative level of ß-lactams and
tetracycline and should not be used as the sole criteria for concentration evaluation.
PRINCIPLE
The Twinsensor (or ,Tetrasensor) dipsticks are qualitative, nitrocellulose membrane
based immunoassay for the detection of antibiotics in food products. The principle is
described in each kit insert and can be obtained from the web site
www.twinsensor.com and www.tetrasensor.com.
PRECAUTIONS:
• Read the kit insert Manual carefully before installation so as to ensure
proper operation of the analyzer from the outset.
• Do not use any components of the kits after expiration date.
• Do not eat, drink or smoke in the area where the specimens or kits are
handled.
• Handle all specimens as if they contain infectious agents. Observe
established precautions against microbiological hazards throughout the
procedure and follow the standard procedures for proper disposal of
specimens.

STORAGE AND STABILITY
The kit can be stored refrigerated (2-8°C). The test device is stable through the
expiration date printed on the label. The microwells and dipsticks must remain in
their original sealed pouch or bottle until use.
WARNING: Do not freeze. Do not use beyond the expiration date.
2.2 Measuring principles
The Readsensor uses the incident light emitted by an internal light source reflected
by the test strip surface as primary information. In other words the reader sees
exactly the same thing as the human eye does, except the fact that the colour of the
light source is adjusted to the spectral properties of the test strip in order to improve
contrast and sensitivity. That is why green light is radiating from the insertion window
during the measurement.
CAUTION: As the reader sees the same way as the human eye does, it is
subject to the same interfering effects. No other object should be placed over
the test strip before insertion. The surface of the strip should be plain, no
bending of the strip is allowed. The surface must be free of scratches and
other disturbing objects (drawing, writing, dust etc.). It is recommended to
take care of the correct positioning of the strip, otherwise it going to give
incorrect results.

The reflectance image is projected with an optic onto a CCD sensor, which resolves
the picture into 320x90 pixels along the test strip. The optical density curve has a
lower value in positions where the strip is dark and it has a higher value where the
strip is close to white. The reader does all further processing on the resulting optical
density curves.
The user moves the dipstick under the LED reading head and the mirror. The
analyzer reads the control, and the test lines on the dipstick. Reading is done
electro-optically, as follows:
The LED (1) emits light of a defined wavelength on to the surface of the test pad (2)
at an optimum angle. The light hitting the test zone is reflected more or less intensely
depending on the darkness of the lines on dipstick, and is picked up by the detector
through a mirror and a lens. The lens produces an upside-down image on surface of
the CCD (3). The CCD consists of an A/D converter, and sends a digital electrical
signal to CPU. Then the microprocessor (4) converts this digital reading to a relative
reflectance lighting curve by referring it to a calibration standard (blank) lighting
curve.
The reader calculates a ratio number from the integration area of the coloured lines
on the test Dipstick surface.
Test dipstick is read photometrically after a lead (incubation) time. The CCD can see
the entire surface of the test strip, but it is directed onto a 32 pixel wide zone of the
relevant reaction area. The „footprint” of the optics – the area, which is projected
onto the sensor array - is called the field of view (FOV).
READSENSOR INSTRUCTIONS
-
Version 1.3
15 - 38
December 2007
The width of the dipstick is about 5mm and it is measured in the cross direction of
the strip. The limits of the FOV are measured along the strip and are fixed for all
Readers. The reader recognises the darkness and colour change only within the
FOV.
The illumination of the test strip and the sensitivity of the CCD element are not
uniform along the FOV and not constant in long term. Due to these facts the reader
has to make a white calibration or blanking on a regular base. With the blanking
procedure it is possible to equalize the non-uniformity of the optics as it is shown
above. After a blank calibration a blank Dipstick is measured to have the same
colour at each position.
WARNING: The blank calibration procedure is essential for the proper
operation of the ReadSensor that is why the operator is forced to repeat it
regularly.
During real measurements, which may only happen after a blank calibration, the
equalized optical density curve (relative reflectance curve) will look like shown below.
ρ(x)

The evaluation of the Twinsensor or Tetrasensor dipstick is the following: There is a
control line and two test lines on the dipstick of the Twinsensor and only one test line
on the dipstick of the Tetrasensor. The reader calculates a ratio number from the
integration area of these coloured lines on the reagent surface then compares this
ratio with defined calibration curve range limits and outputs a qualitative result.
*The photometrical precision of the device remains below the precision of
immunological measurements. The accuracy of the system derives from the dipstick.
Please, refer to the User's Manual of the kit product for further information.

• 1 Readsensor
• 1 Dipstick tray
• 1 AC Adapter
• 1 AC connecting cable for the adapter
• 1 roll of thermo printer paper
• 1 User's Manual
CAUTION: To ensure your readings are always accurate, do not set up
Readsensor in close proximity to devices that create high-frequency fields, as
they may interfere and produce false results. Such devices include, for
instance, walkie-talkies, mobile telephones, microwave ovens and diathermic
equipment.
ATTENTION: In the event of damage to goods during transit, contact your local
representative.
ATTENTION: If your analyzer has been exposed to marked changes in
temperature and/or humidity wait for it to acclimatize sufficiently before
operating it.
4.2

message on the screen, please open the printer cover and check whether the
code pin is properly placed in the nut on the left of the printer paper roll. The code
pin should be sitting firmly in its position, if it is loose, insert it properly. This
happens whenever the instrument is switched on. If an error occurs, consult the
User’s Manual or contact your local Readsensor representative.
Basic initial settings before starting any measurement
Normally, there are three things to do before starting the first measurements.
- Insert a new paper roll if there is no paper in the printer
- Set the proper language
- Check the date and time
Paper insertion
Flip open the printer cover of the instrument (instrument must be switched on). The
paper roll is easily inserted if it is cleanly cut with a scissors. Hold the printer paper
with the thermosensitive side facing downward and insert it into the lower printer slit.
Press the linefeed function key. The paper is automatically fed in. Let the printer
proceed with the paper insertion until several centimetres are visible on the printer’s
output slit. Press the left function key "Stop", close the printer cover with one hand,
and use the other hand to feed the paper in such a way that it protrudes above the
printer cover and is not jammed. This avoids malfunctions.
ATTENTION: To remove the printed test report, tear off the paper by pulling it
in front across the edge of the printer cover. The paper must protrude above
the slit.
(5) In order to insert a new paper roll, first remove the eventual remaining piece of
the previous roll. If necessary pull the paper out from the upper paper-out slit.
Reverse movement of the paper is not possible, forcing the wrong direction
can lead to damage. Take a new paper roll, cut off the adhesive tape if
necessary and cut a clean, sharp edge for insertion. Open the printer cover and
put the paper roll into its position. Take the edge of the paper and insert it
horizontally into the paper-in slot. The smooth, shiny side (outer surface of the
roll) should be facing down otherwise there won’t be any normal printout. Using
the user menu and the pushbuttons, enter the menu Setting \ Output \ Print/Send

\ Printer \ Linefeed \ Start. The printer should start forwarding blank lines on this
action, the paper edge should be adjusted into the paper-in slit until the paper
forwarding mechanism of the printer takes hold of it. When the paper length at
the paper-out slot has reached about 2-3 cm press the Stop button for a second
to finish the linefeed procedure. After this, close the printer cover so that the
paper juts out through the printer cover’s slit.
(6) To set the language of your choice, press the key sequence "Settings / Output /
Display / Language" (see Sections 3.2 and 3.3).
(7) Press the key sequence “Settings / Output / Display / Date/Time” to set the
proper date and time settings (see Menu Structure, Section 3.2).
(8) Readsensor leaves the factory with the default settings for Printer, Language and
Date/time (see Menu Structure, Section 3.2). If your laboratory works differently,
individual preferences can be entered via the menus.
Power-off
We recommend that the analyzer be switched off at the end of each working day and
that the mains adapter be unplugged from the AC wall socket (see Section 7,
Cleaning)

5 Check measure
Readsensor is calibrated before leaving the factory. When installed, it must be
recalibrate with Check Dipstick before the first samples are read, and thereafter
every hundredth measure. Check Dipstick strip has three check lines on it. That is
standardized to give constant, defined reflectance readings. The purpose of the
check measure is to verify for ageing effects, failure and infection of the optical
system. Check lines on the check dipstick have exact area values, which required
during the check measure. If the measured value is not in the limits the normal tests
probably will not valid.
Procedure:
Press the middle function key ("CHECK") to carry out the Check measure.
1. Take a blank calibration(See section 6.1)
2. Remove a Check Dipstick from the Check Dipstick container. Be careful not to
touch the check line surface and do not allow that those to come into infect with
anything.
3. Insert the Check Dipstick, with the check lines facing upwards, to the Reader
leading. Before calibrating, ensure that the Dipstick is clean and the strip is not
scratched.
ATTENTION: It is very important that the Check Dipstick locks into the
instrument correctly in order to ensure the quality of the calibration
4. As the reader recognised the Check Dipstick, it starts to carry out the reading and
the evaluation automatically. Check line 1, 2 and check line 3 on the strip are
read.
5. Check line areas are printed and displayed on LCD but is not stored in memory.
Remove the Check Dipstick.
CAUTION: Regular Check measurement is necessary to ensure the quality of
the results obtained. Unisensor SA. cannot warrant the correctness of results
if the system is not checked regularly.
ATTENTION: You can make a Check measurement at any time, even if the one
hundred measures have not elapsed since the last calibration, for example if a
Readsensor Test Dipstick has returned an implausible result. Start the Check
procedure by pressing the middle function key (“Check”) with the analyzer in
main menu. Follow the calibration procedure described section “Check
measure”.
Calibration errors
In case of an invalid check measure the equipment does not give any error
messages.

6 Normal measure
6.1
Blank calibration
Readsensor is very easy to use. The first step of a measurement series is the blank
calibration. This blank calibration is necessary for the equalization of the optics, for
more details refer to the section “2.2 Measuring principles”. The blank calibration
is valid for twenty-four hours. The blank calibration should be performed with an
unused, white and clean test. The reader checks the correct positioning of the strip
and the calibration will not be carried out with a not properly placed strip. It is
important to perform the calibration carefully because a wrong calibration
might spoil all following measurements.
If there is no valid calibration, the first time must carry out one. The reader will
display BLANK STRIP and asks for a blank Dipstick for blank calibration. Insert a
blank Dipstick into equipment. If the white test was already inserted, “<<PULL
DIPSTICK OUT<<” message appear on LCD. The Dipstick has to be removed and
reinserted, the reader does not accept any strip already residing in the optics at the
start of any measurement. In the other case “>>PUSH DIPSTICK IN >>” message
displayed on LCD. When the strip is accepted the reader will display BLANK IN
PROGRESS in the first line. After it automatically set the lighting for the correct
reading (it is the countdown on the LCD).
The purpose of calibrating the analyzer is to compensate for ageing effects that
influence the optical system. If the compensation needed is excessive, for example
because the test strip is badly soiled, or an LED is defective and cannot emit the
required amount of light, an error message is displayed (see below).
Procedure
1. Tear off a normal Dipstick (The Dipstick must be totally blank and clear). Remove
the Dipstick from the bottle. Be careful not to touch the surface of strip in the
Dipstick and do not allow them to come into contact with anything.
2. Press the left side button (“Start”). “BLANK STRIP” appears.
3. When “>>PUSH DIPSTICK OUT>>” appears, place the calibration strip, with the
test window facing upwards and out with the sample-tearing window.
ATTENTION: It is very important that the blank Dipstick locks into the
instrument correctly in order to ensure the quality of the calibration
4. Equipment set the correct lighting. An acknowledging beep sounds. Remove the
blank Dipstick. It may use for an hour yet to normal measure.

Sample preparation and application
Follow instruction in:
KIT INSTRUCTIONS
Doc: TWINSENSOR / V1.6 (or upgraded).
This document is provided with each kit.
CAUTION: There are a few aspects that should be kept in mind during
measurements:
• The reaction time has to be kept accurately.
• The correct test dipstick positioning is essential, the dipstick must be
planar with both top and bottom part included in the furrow of the rapid
designer. Some dipstick might be a bit large or small and you should
regard this as a major when loading the dipstick on the furrow.
• There are some disturbing effects that the reader itself cannot detect. The
reader can not distinguish big scratches from coloration, thus strips with
such defects should not be measured or the measurement result has to be
used cautiously.
ATTENTION: To ensure that Readsensor is carried out correctly, read the
package insert included with the test strip.
If the Dipstick was already inserted, “<<PULL DIPSTICK OUT<<” message appear
on LCD. The Dipstick has to be removed and reinserted, the reader does not accept
any strip already residing in the optics at the start of any measurement. In the other
case “>>PUSH DIPSTICK IN>>” message displayed on LCD. Insert the Dipstick into
the slot of the optics with a single continuous movement. If the strip is stopped
during its course for a longer period of time (1-2 seconds) the reader might
start the measurement. Such operation could lead to false readings despite of the
thorough measurement validity checks that the reader performs during result
evaluation. When the reader accepts the strip as stabilized it starts the measurement
procedure indicated by READING IN PROGRESS in the first line of the display. After
a few seconds the result is evaluated and is printed on paper and on demand lineby-line on the LCD screen. If the reader does not accept the strip as a valid test strip
(e.g.: missing control, reference line, or test redrawn during measurement) E06:
STRIP INVALID error message will be displayed.
5. When “>>PUSH DIPSTICK IN >>” appears, place the Dipstick, with the test
window facing upwards and out with the specimen-tearing window.
6. When Dipstick is measured, calculating the result and print and/or send it.
7. Selecting the “Measure” menu point to take another measure.
After the completion of a measurement a new one can be initiated by selecting the
“Measure” menu. This will restart the measurement procedure.

NEGATIVE, one LOW POSITIVE and one POSITIVE.
These are the following:
For Twinsensor:
POS
when TEST / CTRL (B/C or T/C) =< 0.9
LOW POS when 0.9 < TEST / CTRL =< 1.1
NEG
when TEST / CTRL (B/C or T/C) > 1.1
For Tetrasensor:
POS
when T/C =< 0.95
LOW POS when 0.95 < T/C =< 1.3
NEG
when T/C > 1.3
For the visual interpretation of the measurement results, please, refer to the User’s
Manual of the Test Dipstick.
8 Cleaning and Maintenance
Readsensor is designed for maintenance-free operation. Protect the instrument from
extremes of temperature and high atmospheric humidity (see Section 10), and keep
it out of bright light (direct sunlight, spot lamps, etc.).
Maintain hygiene by keeping the exterior parts and surfaces of the instrument clean.
For cleaning apply a commercial cleaning agent or disinfectant (preferably 70 %
alcohol) with a moist cloth. Take care that no liquid enters the instrument.
9 Error and warning messages
The Readsensor has an intelligent error detecting system to minimize the error of the
routine test. In case of an error, together with an audible signal and the blinking of
the LED in red, a message appears on the display. An error / warning message
consists of an error code and a short text refers to the source of the error.
In case of the error messages the reader stops its functional working, what can be
continued only after the action of the user.
In case of the warning messages the reader pauses its functional working for the
short period of the warning and steps back automatically to the previous screen.
The possible error and warning messages, the possible causes and troubleshooting
are detailed in the following:
E04: WRONG CODEKEY
The chip module on the left of the analyzer
underneath the printer cover is not valid or damaged.
Check the codepin and change to a proper one.
E05: NO CODEKEY
The electronic codepin is not correctly inserted. Insert
the codepin correctly.
