TC-720PLUS

CHAPTER 1 INTRODUCTION The TC-720PLUS urine chemistry analyzer is a semi-automated analyzer for urine chemistry analysis. This analyser has been manufactured and developed with advanced technology using modern microprocessors, optics and electronics. The TC-720 PLUS uses testing technology utilising a cold-light source, integrating sphere, and modularised blocking systematical design which enhances the stability of the optical system. This system also automatically compensates for the influence of ambient and scattered light through the coordination of software and hardware. The TC-720PLUS can test for 11 parameters including Glucose (GLU), Urobilinogen (URO), Bilirubin (BIL), Ketones (KET), Specific Gravity (SG), Occult Blood (BLD), pH, Protein (PRO), Nitrite (NIT), Leukocytes (LEU), and Ascorbic Acid (AC) in 60 seconds.

The TC-720PLUS can test the following Urige Test Strips: URS-2P URS-4S URS-7 URS-2K URS-5K URS-7L URS-3 URS-6 URS-8

URS-9 URS-10 URS-11

The TC-720PLUS has the following characteristics: 

LCD Touch screen



Patient ID profile entry



Automatically determines patient urine color



RS-232 Interface



Temperature indicated on the LCD display



Easy to Maintain



Run up to 500 tests / hour



Contains internal waste tray



2000 tests memory



Results searchable by date or Patient ID number



Random Test Mode or Continuous Test Mode



Marks abnormal results



Primary and Secondary wavelength reading for automatic correction



The analyzer is only compatible with the Syntron Bioresearch URS line of Urine Strips.

If strips other than Syntron Bioresearch URS are used then results may be inaccurate.

TC-720PLUS The TC-720PLUS can determine the intensity of different colours on the reagent strip test area. It measures colour intensity by irradiating the test pad with white light and detecting the reflectance on the test pad with an integrated sphere photo-detector. This photo-detector is filtered to measured wavelengths of 525nm, 550nm, 620nm, and 720nm. 720nm is the reference wavelength and the combination of 525nm, 550nm and 620nm lights are to differentiate the color intensity. Results are calculated by a reflection rate (R%) which is a percentage of the total reflectance of the testing wavelength and are printed automatically. If the intensity of colour on the strip is high then the reflectance will be low conversely if the intensity of the colour is low then the reflectance will be high. Apart from there being strip blocks for each test there is also a reference block (blank) on the strips. Its function is to rectify any error that may be caused by the colour or the urine itself. The formula for reflectance is:

Tm·Cs R(%)＝ Ts·Cm

R： Reflectance Tm： The intensity of reflected radiation of the strip block to testing wavelength Ts： The intensity of reflected radiation of the strip block to reference wavelength Cm： The intensity of reflected radiation of the reference block to testing wavelength Cs： The intensity of reflected radiation of the reference block to reference wavelength

Please read the TC-720 Plus-720 PLUS Operator’s Manual carefully before installation, to ensure proper operation of the analyser.

TC-720PLUS

Set-Up (I) Installation of the TC-720 PLUS When the analyser has been switched on, it will go through a series of self diagnostic checks. During this time malfunction codes will show if there are any problems with the analyser. Please refer to the service manual for further assistance. Urine controls are recommended to verify the results against the ranges provided. If there is a deviation in the results, please report the result to technical support.

Caution: Make sure that the current and voltage of the power supply is stable before use or the analyser may be damaged.

Figure 3: Startup Menu If malfunction ‘9’ appears during the instruments initial set up, it is possible that the strip platform is not properly in place and has shifted during transportation or the strip rack may have been blocked. The following procedure can be used to resolve this.

Press

to enter into the main operational menu (see Figure 4), then press

Setting, press

or

to enter into the menu (see Figure 7), then choose Move, press

(II) Touch Screen Calibration The calibration procedure should be initiated before use. At the startup screen, press

+

finger, and touch each dot. Press the

key to enter the operation menu. ‘Press this dot’ will blink. Use your index key to confirm and then

to exit.

(III) Changing Printer Paper CAUTION:  Make sure the thermal paper is dry before installation. The printer will stop working if the thermal paper appears wet.  The printer will not print if the wrong side of the thermal paper is inserted since it is coated on one side only.  Do not run the printer without any thermal paper installed. The printer head may be damaged. Instructions for changing printer paper: Turn on the TC-720 PLUS; remove the printer cover by applying steady upward pressure to the rear of the cover. Secure the printer paper in the printer bed and place one end of the paper under the rubber wheel. Lift up the puller rod as in Figure 5 and rotate the printer Knob to engage the paper. Close the puller rod. Press

to enter main menu screen. On the menu screen toggle (using arrows) to Paper Feed and press

this will advance the paper. Make sure paper is advancing properly. Replace the cover making sure that the printer paper is placed through the slit on the cover.

Once the analyser is turned on and the self diagnostics is complete. Press menu. Press

to enter the main operational

to enter previous menu.

Figure 10: Correct Strip Loading

Place the urine test strips in the rack position exactly as shown in figure 10 above to prevent the analyser from jamming.

4.8

Testing a Strip

In the main menu, using the arrow keys select ‘test’ and press

. At this time the analyser will beep a series of times. Dip

the test strip into the urine for no more than 2 seconds making sure the urine comes into contact with all test pads. Blot the strip on an absorbent piece of paper and place on the strip rack ensuring the end of the strip just touches the back of the test board. A) Do not dip the urine strip in urine for too long as this may affect the results. B) After sampling, immediately place the urine test strip on the analyser test board. Delays may cause the test pads to darken giving false negative or highly abnormal results. C) The test strip is a consumable - do not attempt to reuse D) If a MALFUNCTION occurs during a test, check the trouble shooting section of the manual to fix the problem and rerun the test.

TC-720PLUS

Figure 11: Pre results screen The test rack will begin to rotate and the strip will enter the analyser. At this time the analyser will again beep several times. Dip the next urine strip into the next sample, for 2 seconds, blot on absorbent paper to clean off excess urine and place in the next appropriate rack position on the analyser. After 5 seconds the analyser will beep again and the test strip will enter the analyser. The strip rack will move one position every 5 seconds and will move the strip along the strip carrier (conveyer belt) until it reaches the reading position after 60 seconds. The strip will then be read and the results will be printed. (1) Please read the instructions on how to handle Urine Reagent strips located in the package insert included with each bottle of Urine Reagent Strips. (2) The urine test strip is a one-use product and must only be used once.

SPECIAL DIRECTIONS Do not move the analyser while a test is running. This will cause the analyser to malfunction. The TC-720 Plus analyser will begin to test the first test strip after 60 seconds and can test one test strip every 5 seconds thereafter. The analyser will automatically keep the data for all test results, and synchronously display and print these test results The analyser can continuously load strips with the conveyer belt test strip carrier. When the analyser is in test mode and is testing simply place a test strip in the next position to run a test. If testing is completed or the testing in process needs to be stopped, exit from the test status can be achieved by pressing and holding

(I) Print On The default printer setting for the analyser activates the internal thermal printer. The analyser can also be set to use an external printer. These settings can be changed using the “Print On” function in the Parameter Menu. When using an external printer the status of the printer cannot be controlled using the TC-720 Plus analyser. The printer must be appropriately set up to communicate with the analyser. “Print On” – Means the TC-720 Plus will print from the internal thermal printer “Print Off” – Means the TC-720 Plus will not print from the internal printer but send the results to an external printer linked to the TC-720 Plus analyser
