METHODS OVERVIEW
2 OF 2
2.1 Introduction
The CLINITEK® Status instrument is a reflectance photometer, which reads the
changes in color of the Bayer urine reagent strips and immunoassay cassettes. A
series of six light emitting diodes (LED) each at a different wavelength illuminates
the entire strip or cassette length. Reflected light from the strip is then passed
through a lens and focused on a photodiode detector array (CCD) which then
converts the light energy into an electronic signal. This signal is then passed
through an A/D converter and then onto a microprocessor. Once there, the signal
is processed into percent reflectances and then decodes. These decode values
are compared to lookup tables containing specific decode ranges for each
reagent and their respective clinical values. Results are reported to the customer
via the touch screen, onboard printer, and/or through a computer interface.
For methods used on the urine reagent strips and immunoassay cassettes, refer
to their specific product inserts.

6.1 General Description
The Clintiek Status urine analyzer is a reflectance photometer designed to provide
semiquantative clinical results when used with Bayer Urinalysis test strips and
imuno assay cassettes. The instrument can be broken down into the following
subsystems:
Optical system
The Processor
User interface
The optical system provides both llimation of the test cassette of strip using light
from six LEDs. This light is directed on to the test surface by a light plastic light
guide that provides unforim ilumation across the length of the read area. This light
is then reflected off the read area to a mirer which directs the light to a lens that
focuses the reflected image onto a CCD array.
The Clinitek Status optical system reads the entire length of the read area in one
reading. The image of the read area is refected and focused on the CCD array, each
element of the CCD array is then clocked out, amplified ,sent to a 10 bit A/D
convertor, and the digital value to each ellemnt is then stored in an array in the
instruments memory. This entire process is refered to a “Scan”. When a test is
processed the system will scan the read area ten times and averaged, thus the
average of the ten scans are used in the instrument aliogrothms for generating the
clinical results. At the start of eact test the instrument scans the white calibration
bar on the table to calibrate the instrument so that the sample refletance readings
can be determined. Test results are displayed on the screen, they can also be printed
on the internal printer or sent out the serial communcations port.
NEXT
THEORY OF OPERATION
3 OF 11
6.2 LCD display and Touch Screen assembly
The LCD display and Touch Screen assembly is the primary user interface for the
instrument. The LCD and integrated touch panel are supplied as a semi–
customised assembly with a housing that directly attaches to the upper cover of the
instrument. This provides a fluid resistant and electrically resistant seal to the
housing. The assembly contains electronics that convert a serial stream of 4 bit
wide data along with some necessary control signals to the electrical signals
necessary to excite the LCD panel itself. The LCD then provides a 320 by 240
monochrome, single level (Black or background) display for viewing by the user
from a single 5V supply and TTL/CMOS signals. An analog voltage input from the
main PCB can then vary the contrast of the whole display. The LCD is interfaced
directly to the main PCB by a single 14 way Flexible cable with printed connector.
The 8 by 6 touch screen overlay is completely passive and contains no electronics.
It provides an 8 by 6 crosspoint matrix of normally open resistive switches on a
second 14 pin flexible cable with printed connector for direct interface to the main
PCB. These crosspoints are scanned sequentially by the main board electronics for
any closures. Should multiple closures be detected (which may be ambiguous), the
software in the main board decides on the outcome of these scenariosThis unit
contains embedded electronics to format a 4-bit wide data stream into a 320 by 240
pixel display and control the contrast of the display. The resistive touch screen
provides an 8 by 6 passive overlay on the LCD.
NEXT
THEORY OF OPERATION
4 OF 11
6.3 Main PCB
A single PCB that contains all of the necessary control circuits is mounted on the
This “Main PCB “contains the following:
a. The Microcontroller used to control most of the functions within the instrument is
a Hitachi H8/3006. This component incorporates an internal 32 bit CPU architecture with a 16 bit register set along with embedded RAM, timers, serial communications, memory interface, DMA, I/O ports, ADC and DAC functions. In this
design it is powered from the 5V supply and receives a system clock from an
external oscillator at a frequency of 18.432MHz. External RAM and ROM
(Flash) support the Microcontroller. A large number of the pins / ports on the
device are used for this high-speed interface.
The on chip serial communications controllers are used to interface with the
external RS232 interface, an internal serial interface to a future expansion card
and to the SIP bus that communicates with the NVM, MMC card and RTC.
In general, the I/O ports on the processor are used as inputs and the output
functions are segregated to the U26 CPLD, as there are insufficient on-chip
ports to meet all of the system requirements. The digital input ports come from
the touch screen sensing, power state sensing, drawer position sensing & printer
status.
The timer / counters are used to provide:
A general system timing function.
The sounder drive.
The PWM modulation for controlling the speed of the drawer mechanism.
NEXT
THEORY OF OPERATION
5 OF 11
The LCD interface which stimulates the DMA to transfer the display image
repeatedly independent of the CPU operation.
The CCD interface which stimulates the ADC and DMA to transfer data from the
CCD into memory independent of the CPU operation.
The 8 bit DAC’s are used to set the LED illumination level when scanning the
sample, the contrast level on the LCD and the offset adjustment to the CCD
variable gain amplifier.
The 10 bit ADC is used in conjunction with its input multiplexer to sample analog
voltages from the CCD, the raw supply voltage, the printer head current and
head temperature and the drawer motor current.
The Microcontroller is reset by an external device (U11, via U26). U11 also
provides a watchdog function so that the instrument is stopped from operating in
the event of a timeout.
b. The External Memory provided consists of a single 512K byte Static RAM device
for transient data and a single 1 M byte Flash ROM device for the program
memory and static data. The ROM is initially assembled onto the PCB with a
boot loader pre-loaded into it. Subsequently, the ROM has the ‘Status’
application loaded into it during board test using the serial port at high speed. In
service, the ROM can be updated either from an MMC card being inserted into
the MMC connector from under the printer cover of the instrument or from the
serial connection should it be required.
c. The Programmable logic device (CPLD - U26) is generally used to provide
output latches and hardware processing functions that were not available on the
Microcontroller. The device is a flash memory programmable device and can be
reprogrammed in-situ by attaching a programmer to the connector position

provided on the PBA. The CPLD complexity is quite low (72 storage elements)
and so only provides simple functions. In particular, it converts and re-times the
8 bit data into 4bit data for interface to the LCD, drives the touch screen inputs,
the printer head and paper feed functions, the sounder, the sample drawer driver,
the CCD amplifier gain and the power switching functions.
d. The LED Driver circuit has a digital part that switches on the appropriate LED
when required (under CPU control) and an analog part that converts the voltage
output of one of the Microcontroller DAC’s to a current output. The current is
then used to vary the drive level of the LED’s used for illuminating the sample.
Additionally, two of the digital outputs from this circuit control the power to the
drawer position sensing opto-couplers.
e. The Variable Gain Amplifier is used to amplify the signal from the CCD on the
Emitter / Detector PCB before application to the ADC in the Microcontroller. The
gain of this amplifier is by default set to +2, but may be set to gains of +1, +3 and
+4 as well when required by the Microcontroller via output ports in the CPLD. To
accommodate the voltage offset from ground of the CCD signal compensation is
applied to the amplifier by a DAC on the Microcontroller.
f. The Drawer Motor Driver takes a PWM signal from the Microcontroller, a
direction signal and control signals from the CPLD and produces a high current
‘H Bridge’ drive to the brushed dc. motor. This allows the drawer motor speed
and direction to be altered by the Microcontroller as well as providing braking of
the motor when required. A circuit to allow sampling of the drawer motor current
for future use is also provided that feeds into an ADC channel on the
Microcontroller.
NEXT
THEORY OF OPERATION
7 OF 11
g. The Drawer position sensors mounted on the flexible cable assembly are driven
by two outputs from the LED driver circuit and the signals returned from the
sensors interfaced to digital inputs on the Microcontroller via the CPLD.
Additionally two signals are generated by the CPLD to drive interrupt inputs on
the Microcontroller in order to provision for fast servicing of the drawer position
state when required.
h. The non-volatile memory (NVM) device is a serial EEPROM device that can
store 256k bits of data as 32K bytes of storage that is retained without power on
the instrument. The device is used amongst other things for the storage of
instrument set-up data and calibration data.
i. The Real Time Clock (RTC) device is a serial device that stores the current date
and time and is powered from the Instrument 5V supply when it is present or
from a permanently fitted primary lithium cell when the instrument supply is not
present. The device communicates over the SPI bus with the Microcontroller,
using its own protocol. The device has its own 32.786KHz crystal timing source.
j. The Multi-Media Card (MMC) interface is comprised of a connector and some
protection components, so that an MMC card can be inserted into the connector
and read over the SPI bus, using the SPI protocol. The data recorded on the
card is for the purposes of software updates in the field. A specially formatted
card is recognised at power up and read into memory so that reprogramming of
the software application can take place.
k. The Sounder is a simple ceramic capsule fitted to the main PCB. The sounder is
driven in a bridge mode from two outputs of the CPLD. The frequency of the
sound is derived from one of the timers on the Microcontroller.
NEXT
THEORY OF OPERATION
8 OF 11
l. The Printer Paper Feed Driver is a stepping motor driver that is stepped using
two signals from output latches in the CPLD using a gray code sequence. The
device boosts the current capabilities of the CPLD and provides a bipolar drive
for each winding of the motor. An analog circuit monitors the current that the
motor windings are consuming and chops the waveform to keep the current at or
below one of two predetermined levels that can be set by the Microcontroller.
m. The Printer Head monitoring circuits buffer and amplify the head current and
head temperature signals before sending them to the ADC on the
Microcontroller. The head temperature should not normally exceed a pre-set
temperature, in the event that it does the software turns off the instrument. The
printer head current is monitored by amplifying the voltage across a low value
resistor in series with the head elements. The signal is then sent to the ADC on
the Microcontroller.
n. The Printer “head up” and paper out opto sensors on the printer are powered by
main board through resistor feeds and are interfaced back to the Microcontroller
for digital sensing of the states of these signal in order to inhibit printing under
paper out or head up conditions.
o. The RS232 Interface acts as a level changer between the 5V logic levels
required at the Microcontroller pins and the +/- 6V (min) signals required to meet
the RS232 specification at the connector on the end of the flexible cable
assembly. The device used is a +/- 15KV ESD compliant part with on board
charge pumps to generate the required voltages for the interface.

6.4 Printer
The printer is a thermal printer that prints rows of 384 dots as required across the
special paper supplied from a roll. The paper is then moved so that the next row of
dots can be printed to build up a pixel by pixel graphical image on the paper. The
electronics in the printer takes a serial stream of 8 parallel inputs and determines
which of the thermal heads should be energized. The printing head electronics also
contains a temperature sensor that monitors the temperature of the printhead. This
electronics is connected directly to the main PCB via a high current, 20 way flexible
cable with printed connector.
The paper feed to expose the paper and print the next row of dots is driven by a
simple stepping motor. There are no electronics to drive this motor in the printer.
The two motor windings are presented directly to the main PCB electronics via a 9
way flexible cable with printed connector. On the same flexible cable, the
connections to two opto-couplers that sense the printer head position and paper
present conditions are provided for action by the main PCB electronics.
A 5V logic supply and a 4.2 – 8.5V power source from the main PCB power the
printer. The current taken by the printer has to be actively managed by the main
board electronics to provide an acceptably dense and even image and regulate how
much power is consumed at each printing operation.

6.5 Interconnection
A flexible printed circuit assembly provides the interconnections between the main
PCB to the power supply, Drawer mechanism, battery pack and RS232 connector.
At one end it has a 30 way FPC male connector printed within it for connection to
the main PCB. The connections from the main board connector are then distributed
to the other connectors and assemblies directly attached to exposed pads on the
flexible printed circuit.
Connections are made to:
a. The power inlet connector (with EMC ferrite in line), the RS232 connector with
EMC ferrite on connector pins.
b. The battery pack via soldered interconnect leads.
c. The drawer opto-coupler positional feedback devices mounted on a small rigid
section of this circuit.
d. The drawer motor and noise suppression component(s).

7.1 Introduction
This chapter is divided into two different sections. The first section is devoted to
troubleshooting tables and error code tables giving a brief description and steps the
customer and service individual would need to take. The second section goes into a
description of the diagnostic screens available on the instrument.

7.2 Troubleshooting Table
The following table is provided to assist in troubleshooting the CLINITEK Status
system. The first four columns are similar to those found in the Operators Manual
under troubleshooting with the exception that “Contact Bayer Service” has been
removed from Customer Remedy column and replaced with “Replace instrument.”
The fifth column, “Service Remedy,” gives a more advanced troubleshooting guide
that should be utilized by Bayer Service Personnel or under the guidance of trained
personnel. The items are listed in increasing order of technical difficulty.
In some isolated cases, the power plug must be unplugged from the back of the
instrument in order to turn the instrument off or batteries removed. Once the plug or
batteries has been replaced, the power button on front of the instrument must be
pressed to turn the instrument back on.

8.2 Test Table and Insert
The Test Table should be replaced when there is a potential problem with the white
calibration bar or the molded teeth on the underside of the table. These teeth are
used by the drive motor to move the table in and out of the instrument and any
issues with them may cause improper table movement.
NOTE: No Lubrication is needed and should not be applied to the teeth on the table or drive
gear attached to the motor.
1 The test table does not need to be removed from the instrument in order to
replace the insert. When the instrument is powered on, the table should be
extended to the ready for test position. If it is not, power down and power back
up to reset the table to the ready position. This ready position will allow for the
easy removal of the insert and placement of a new insert.
2 If the Test Table will not move out of instrument, place the instrument upside
down on a soft, clean surface and remove the bottom cover by removing the
black Philips head screw.
3 While holding the instrument in the upright position, use your finger on the
underside teeth of the table to gently push the table out. You must hold it upright
for the shutter to open with the table.
4 Advance the table far enough out that you may pull it out as in step 5.

C.1 Introduction
This Appendix refers to the use and interpretation of the Clinitek Status Check
Cassette, PN 9333. This cassette is to test the system hardware and is not
intended and should not be used to check the system performance. System
performance testing requires the use of commercial controls such as Chek-Stix.
The procedure for running a cassette and the error code list is provided here.
WARNING: The use of the Clinitek Status Check Cassette is to be done under
the supervision of a trained service representative, by the service
center, or when instructed to do so by a trained technical phone
support person.
For service center use, the Check Cassette has an 18 month shelf life from date
opened and if properly stored. It should be stored protected from light and kept free
of dirt. (Hint: Use an old, clean, black plastic Multistix bottle to store the cassette
in.) Avoid leaving the cassette in bright light for any length of time as the light could
cause the deterioration of the color test areas and immuno lines. If any fluids come
into contact with the top surface of the cassette, the cassette should be immediately
disposed of and replaced with a fresh one.
NOTE: For Customer use, the Clinitek Status Check Cassette is a single use item. Once
they have opened the foil pouch and used the cassette they are instructed to
disposed of it and a replacement will be sent to them. The reason behind this is that
the cassette is now outside Bayer’s control and the proper storage can not be
guaranteed.

C.2 Test Procedure
Any time an instrument user is experiencing problems with the instrument and are
not sure if it is reagent or instrument related a Check Cassette should be utilized.
The Check Cassette will provide a simple way of testing the instrument’s hardware
to confirm an instrument issue and decrease the number of unnecessary returns to
service. It does not check the instrument performance. Performance checks need
to be done through the use of commercial controls or Chek-Stix. The Check
Cassette should only be used by the customer while under Bayer supervision or by
a trained service representative.
1 From the main ready for test screen, select “Instrument Set Up.”
2 If the customer has set a password to access the instrument set up, then you
must use the default password, 3654, to gain access to the Settings Menu.
Press the “123” button on the “Enter Password” screen to get the number pad
and enter 3654 followed by “Enter.”
3 The “Choose Settings” screen is now displayed. Scroll down using the down
arrow until “Diagnostics” is highlighted. Press “Select” to enter the next menu
screen.
4 Scroll down the “Select Diagnostics Test” screen until you have highlighted
“Check Cassette” and press “Select.”
5 Turn the test table insert over to the cassette test side.
6 Place a Check Cassette onto the table insert and press “Run Test.”

7 The “Please wait” screen is displayed for about 90 seconds as the instrument is
reading and processing the calibration bar and cassette.
8 Either a “Test Passed” screen or a “Test Failed” screen will be displayed upon
completion of the test.
9 A test passed will indicate that there are no issues with the hardware and that
the instrument is functioning properly.
10 The failed test screen will also have one or more error codes displayed. The
meaning of each error code can be found in Section C-2.
Any errors (failed tests) indicate that the instrument requires service and
must be returned to a Bayer authorized service center for service. A
replacement instrument should be sent to the customer.
NOTE: The replacement instrument will contain a new Check Cassette.
11 A replacement Check Cassette must be sent to the customer immediately if the
outcome of the test indicated no instrument issues (passed test).

C.4 Service Remedy
The Check Cassette testing is mainly focused on the optical components. In all
cases the first step would be to replace the optical chassis. If that fails to correct
the situation, then the main PCB should be replaced.
