Calibration printout
If the new calibration results are within the acceptable range, the message
“CALIBRATION O.K.” is displayed. Results are stored in memory and
automatically printed along with time and date. A list of reflectance values for
measuring positions 1–11 for the orange LED are printed in the middle column
and for the green LED in the right column. (See Figure 8).
Calibration errors
If the results obtained for the reference pad or the calibration strip are outside the programmed tolerances, one of the
following messages will appear: “REFERENCE PAD ERROR !”, “CALIBRATION INVALID !” or “CALIBRATION ERROR !”.
In the event of a calibration error, repeat the calibration procedure with a fresh Chemstrip Calibration Strip. Press the
START button to return to the “START CALIBRATION” menu. Follow the same calibration procedure as above. When the
message “CALIBRATION O.K.” has been printed, proceed with the reading of test strips. If you continue to receive an error
message, see Section 8.
6. Reading Test Strips
6.1 Instrument Overview
The Urisys 1100
®
Urine Analyzer is very easy to use. Simply insert the test strip when the display reads “Insert Strip”, then
press the START button. The analyzer automatically waits for the strip to incubate for 55 seconds before it reads the first
test pad. Seventy seconds after the START button is pressed, the measurement is completed and the test strip tray returns
to the start position. Throughput is approximately 50 test strips per hour.
Each time a test strip is read, the gray reference pad in the tray is evaluated to compensate for temperature and aging
effects that may influence the optical system. If the compensation needed is excessive, for example because the reference
pad is badly soiled or an LED is defective and cannot emit the required amount of light, an error message is displayed (see
Sections 7.1 and 8).
The Urisys
1100
®
Urine Analyzer assigns each reading a consecutive sequence number (sample number) having a
maximum of three digits. The sequence start number automatically reverts to 1 each time the date is incremented. You may
reset the sequence number to 1 via the “New Series” function, for example when one series of measurements has been
completed and another is due to begin.
In Automatic Patient ID mode the instrument will assign automatically unique serial numbers to the tests results which
have no Patient IDs. These unique numbers are ascending serial numbers based on the total number of tests performed on
the instrument and cannot be altered nor cleared.
After five minutes of inactivity, the analyzer automatically switches to Standby mode. The tray advances slightly so as to
close the retaining bar, and the display shows the date and time. The analyzer resumes Ready-to-Measure status when the
START button is pressed.
6.2 Quality Control Recommendations
Commercial control material may be used for quality control. Please contact Roche Diagnostics Technical Service at
1-800-428-4674 for recommended control solutions. Positive and negative controls must be tested daily, or when a new vial
of strips is opened (including every lot change), or whenever calibration is performed. Values obtained for these controls
should fall within the limits established by the laboratory or the control manufacturer. If control values fall outside the
designated ranges, and repetition of the assay excludes errors in technique, contact Roche Technical Service at
1-800-428-4674.
