instrument may be operated at 110VAC 50/60Hz or 220VAC 50/60Hz.

1.2 Instrument Description

The UA-66 Urine Analyzer is a semi-automated, bench top instrument designed to “read” U-11

Urine Reagent Strip for urinalysis. The instrument is initially configured to read U-11 Para.

Reagent Strips. U-11 Para. Reagent Strips are also qualified for use.

The instrument use a high-light white LED as the light source to illuminate the reacted pads,

and use 3 photoelectric sensor at 470nm, 540nm and 625nm to read the reflectance from the

reacted pads.

All the control signals and analog I/Os is processed directly by a Hitachi H8S/2350 MPU. This

makes the instrument simple and reliable.

The instrument uses a Flash ROM as system non-volatile memory to store the system software,

user options and test reports. System software can be upgraded using a personal computer via

RS-232C port. Up to 1000 test reports can be stored in the instrument. The reports can be

recalled via date and sample No.

Reports may be sent to the internal micro thermal printer.

2.2 Initialization Phase

After the power is on, the instrument shows the logo immediately on the display and begins to

perform a self diagnosis and calibration process including the following steps:

1. Check the system ROM and RAM. If incorrect adding sum of the system ROM or failure of

any 1 bit of the system RAM was detected, an E01 error occurs. In this case, the software will

terminate after the error message being displayed.

2. The feed table tries to find the position sensor. If failed, an E03 error occurs. In this case, the

software will terminate after the error message being displayed.

3. The instrument samples the intensity of stray light from the environment. If the intensity is

greater than 100 AD value, an E10 error occurs. In this case, press START to continue.

4. The instrument samples the reflecting intensity of the calibration chip and compares the

values with the original values. If the difference greater than 10%, an E04 occurs.

If any error reported during the progress, refer to 4 Troubleshooting.

Once the self-diagnosis and calibration process completed, the instrument will show the system

main menu including the logo, the software version, operating items, date and time.

2.3 Self-Diagnosis Program

The instrument equips a self-diagnosis program. To run the self-diagnosis program, plug the

RS-232 short connector into the RS-232 port on the rear panel of the instrument and then power

on the instrument. The self-diagnosis program performs a step-by-step check as following.

1. Display Diagnosis

The self-diagnosis program turns the dots of the display on and off column by column first,

then turns the dots on and off row by row. During this period, any defective dots can be found

easily.

If the instrument can’t reach this step, the main board maybe defective.

2. Keyboard Diagnosis

The operator presses all the 6 keys one by one. Once a legal key input is read, the

corresponding key name is displayed on the display. When all the 6 keys are correctly entered,

the self-diagnosis program goes to the next step.

If any key cannot be read, the keyboard is defective.

3. Real Time Clock Diagnosis

The self-diagnosis program shows the current date and time.

If the date or time is not correct, the real time clock need to be correct or the real time clock

chip maybe defective.

If it does not run correctly, the real time clock chip maybe defective.

Press START to go to the next step.

4. Feed Table Diagnosis

Press ▲ to make the feed table to move 2.5mm inward. Don’t do this if the feed table tip is

inside the instrument. Press ▼ to make the feed table to move 2.5mm outward. Don’t do this if

the feed table is near the feed position. If the feed table does not move, the motor or the motor

driver on the main board maybe is defective.

Press ► to make the feed table to find the position sensor. If E03 occurs, the position sensor

is defective.


5. Analog Circuit Diagnosis

The instrument samples the reflecting intensity of the calibration chip once 1 second, and

shows the difference between the current values and the original values.


6. Printer Diagnosis

Open the printer cover on the top of the upper case.

Rise up and put down the handle, the status of the handle will be displayed on the display. If it

is not correct, the handle sensor is defective.

Remove the paper from the printer then insert paper tip under the roller, and the status of the

paper end sensor will be displayed on the display. If it is not correct, the paper end sensor is


- 6 -

defective.

Install the paper correctly, and put down the handle, then press FUN , a test page will be

printed out. If the roller does not scroll, the roller motor or the motor driver is defective. Notice

the full width horizontal line at the bottom of the test page. If any dots lost, the thermal head of

the printer is defective.

Press START to end printer diagnosis.

This step is the last step of the self-diagnosis program.

3 General Maintenance

3.1 Replace the Fuses

Power off the instrument and pull out the line cord from the instrument. Screw off the fuse

holders on the rear panel anti-clockwise using a driver. Replace the broken fuses with the

identical fuses and reinstall the holders back to the rear panel.

3.2 General Cleaning

Keep the exterior of the instrument free from dust at any time. If needed, the exterior may be

cleared using a damp cloth and a mild detergent. Do not use any type of solvent on any part of the

instrument. Do not use any type of lubrication on the instrument. Use of oil, grease, silicon spray,

or any other lubrication may cause damage.

3.3 Daily Cleaning

The feed table and feed table insert must be kept clean to obtain the best result with the OP151

instrument / reagent strip system. At the end of each day use, the instrument‘s white plastic

calibration chip, located on the feed table insert, and the reagent strip holding channel should be

cleaned. To clean the feed table insert, perform the followings:

1. Turn the instrument on. The feed table will move out from the “storage” position to the “load”

position.

2. Grasp the front end of the insert on each side with the thumb and one finger. Apply a counter

pressure with the palm of the hand against the feed table and gently pull the insert outward.

After the insert is completely exposed, lift the front end of insert up and off the table.

Figure 3.1 3. Clean the insert using a cotton-tipped applicator stick or other suitable absorbent material

wetted with distilled water. Thoroughly swab the strip holding channel area until it is clear.

Inspect the surface of the white plastic calibration chip for dust, foreign material, scratches or

scuffs. If necessary, gently wipe the calibration chip with a cotton-tipped applicator stick

wetted with distilled water. Allow the calibration chip to air dry before using. Make sure no

foreign particles remain on its surface. If the calibration chip cannot be cleaned or is

scratched or scuffed, contact the customer service for replacement.

NOTE: Do not use any material that will scratch the feed table insert or the white

plastic calibration chip. Do not use solvents of any kind to clean the calibration chip.

4. Wipe the feed table surface and feed table mounting groove with a damp cloth. Wipe the feed

table dry with an absorbent tissue.

NOTE: Residual water or solution on the feed table or feed table insert will cause

damage to the electronic components inside the instrument.

5. To replace the feed table insert in the feed table:

Hold the feed table insert in the same manner as when it was removed (holding it by the end

opposite the calibration chip). With the front end angled upwards, insert the calibration chip

end about midway onto the feed table. Slide the insert in while lowering the front end until the

insert is laying flat against the table and resistance is felt. Then place the thumb against the

front edge of the insert and two fingers against the underside of the feed table. Apply a

counter-pressure to the feed table while pressing the insert firmly inward. The insert is

properly positioned in the feed table when the front edge is flush with the retain rails of the

feed table.

3.4 Disinfection

4 Troubleshooting

4.1 E01-System Memory failure

Occurs when the instrument was turned on. If the system ROM or RAM cannot pass an initial

self-diagnosis, this error occurs.

The only way is replacing the main board.

4.2 E02 System Data Failure

Occurs if the system calibration data stored in the flash ROM was lost.

The instrument must be re-calibrated by trained service personnel.

4.3 E03 Feed Table Failure

Occurs if the instrument does not detect the table position sensor within a specified number of

motor steps. Possible reasons are:

♦ The position sensor is defective;

♦ The motor driver on the main board is defective;

♦ The motor is defective;

To determine the exact reason, run the self-diagnosis program. If the feed table can not move

in/out when ▲ / ▼ pressed, the motor driver on the processor board or the stepper motor is

defective. If the feed table can move in/out when ▲ or ▼ pressed, but cannot find the feed

position when ► pressed, the position sensor is defective.

4.4 E04 Calibration Error

Occurs during the initial self-diagnosis after the instrument is powered on.

The reflectivity of the plastic calibration chip was found 5% lower than its origin value. Possible

reason is that the plastic calibration chip was polluted or heavily scratched. Do the followings:

♦ Clean the plastic calibration chip as instructed in 3.3 Daily Cleaning.

♦ Clean the plastic calibration chip as instructed in 3.5 Periodic Cleaning.

♦ Replace the feed table insert with a new one.

4.5 E05 Feed Table Polluted

Occurs during the initial self-diagnosis after the instrument is powered on. A reflectivity higher

than 5% was detected while scanning the strip hold channel on the feed table insert.

If any foreign material is in the reagent strip holding channel, remove it.

If the feed table insert is heavily polluted by the urine specimen, clean it as instructed in 3.3

Daily Cleaning. If this doesn’t take effect, clean the feed table insert as instructed in 3.5 Periodic

Cleaning.


- 14 -

4.6 E10 Stray Light Error

Occurs when a background higher than 100 AD value was detected. This check is done before

and after every regent pad is tested. Possible reason is that the location of the instrument doesn’t

match the environment factors. Move the instrument to a place with no direct sunlight and no

working strong light source nearby and try again.

4.7 E11 Positioning Error

Occurs when a test is done and the feed table reaches the most outside position, a position

error greater than 10 pulses was detected. It’s normal if the error occurs once several months. If it

occurs frequently, the feed table assembly needs to be adjusted or even to be replaced.

4.8 E12 Strip Placement Error

Occurs when the strip is not placed correctly on to the feed table, especially the tip of the strip

does not touch the end of the strip holding channel.

This error has no relationship to any parts defective.

4.9 E21 Printer Paper End

Occurs when the thermal printer is out of paper. Install a new paper roll.

4.10 E22 Printer Handle

Occurs when the handle of the micro thermal printer is not in work situation.
