MATERIALS AND  EQUIPMENT: 

  • Urisys 1100 Urine Analyzer (Roche  Diagnostics)
  • 70%  isopropyl Alcohol (alcohol  pads)
  • Lint-Free Wipes  (Kimwipes)
  • Thermographic printer paper
Procedure: 

AT THE BEGINNING OF EACH  DAY:

  1. Install the  clean and dry test strip tray.  Do  not touch the gray reference  pad.  Make sure the retaining bar of the test strip tray is closed  (in the down  position),  and then slide the tray into the  slot located  below the function  keys.
  2. Power-on the analyzer by pushing the on/off switch located at the  back of the analyzer to the ON position.
  3. The analyzer will  perform a self-check ensuring that the test strip tray has  been installed  correctly.  When the self-check is complete, the tray moves to the start position and the retaining  bar opens.  If the self-check is successful, a message "SELF CHECK OK" will  automatically print along with  the time and date.
  4. Calibration must be performed  prior to reading patient samples every day.  The operator will  be prevented from  performing a measurement on patient samples until calibration  is  performed. After 7  days of inactivity the message "REPEAT CALIBRATION" appears after a successful self check.
  5. Use a Chemstrip Calibration Strip  being careful  not to touch the elevated gray areas.
  6. Place the calibration  strip,  pads facing  upward,  onto the test strip tray and  insert the front edge of the strip under the  plastic clip.
  7. Press the  START button.  You will  hear  a beep and then the tray advances slightly, the  retaining bar closes,  and  the calibration strip is read.  When calibration is complete the tray moves to  the start position and  the retaining bar opens.
  8. Remove the calibration strip and save.
  9. If the calibration  is valid,  results  are stored  in memory and  a  report with the reflectance values, time and date automatically prints.
  10. If the calibration results  are outside the programmed limits,  one of the following messages will  be displayed:  "REFERENCE PAD ERROR!",  "CALIBRATION INVALID!",  or "CALIBRATION ERROR!".
  11. If a calibration  error occurs,  repeat the calibration procedure as  above  using a fresh calibration strip.  If the  calibration fails a  second time,  refer to Section  8 in the  Urisys 1100 Manual.

AT THE END OF EACH WORK DAY:

  1. Switch off the instrument.
  2. Pull the test strip tray out of the  instrument.
  3. Rinse  under running water.
  4. Remove any crystalline deposits, especially those contaminating the retaining bar mechanism, with a  soft  brush if necessary.
  5. Wipe down  the test strip tray with  isopropyl alcohol.  Dry with  a soft lint-free cloth. CAUTION:  Be careful not to damage the gray reference pad  during the cleaning process.  Made sure the  reference pad is completely clean and  dry before proceeding to read  test strips.  Also be  sure the positioning hole on the side  ofthe tray is absolutely dry.

ERROR MESSAGES:

  • Error messages are shown on  the display,  but are  not printed out.   If an error message occurs and  there is  no action taken with 5  minutes, the analyzer returns to  standby mode.  lf the  problem is not resolved  and  the START  button  is not pressed, the error message reappears on the display.  See Section 8 of the  Urisys  1100  Urine Analyzer Manual for a description of the error messages.
