Calibration printout
If the new calibration results are within the permitted range, the message "CALIBRATION O.K. " is automatically printed
with a date and timestamp and also a list of reflectance values for measuring positions 1–11 for the orange LED (middle
column) and green LED (right column) (see Figure 8).
Calibration errors
If the results obtained for the reference pad or the calibration strip are outside the programmed tolerances, the following
messages appear: "REFERENCE PAD ERROR !", "CALIBRATION INVALID !" or "CALIBRATION ERROR !".
In the event of a calibration error or if the calibration was invalid, repeat the calibration procedure with a fresh Control-Test
M calibration strip. Press the START button to return to the "START CALIBRATION" menu. Follow the same calibration pro-
cedure 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.
If the analyzer is switched off when one of the above-mentioned calibration status messages is displayed and then switched
on again, it reverts to Ready-to-Measure status following a successful self check, provided that the most recent calibration
was carried out not more than a week ago. Otherwise, the message "REPEAT CALIBRATION !" appears (see above).

6. Reading Test Strips

6.1

Overview

The Urisys 1100 system is very easy to use. Simply insert the test strip when the sample number is displayed (refer to Sec-
tion 6.2), then press the START button to commence reading. The analyzer can be operated in two different modes:
1. In Normal Mode, the Urisys 1100 system 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
moves to the start position. Throughput in this mode is approximately 50 strips per hour.
2. In Fast Mode, which can be selected from the menu, the test strip is measured directly after START is pressed. In this
case, it is up to the user to time the incubation period outside the analyzer (see Section 6.4). Using Fast Mode enables
a 30-second cycle to be maintained.
Each time a strip is read, the grey 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 Sec-
tions 7.1 and 8).
The Urisys 1100 system assigns to 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, if you wish,
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.
Whenever there has been five minutes of inactivity, the analyzer automatically switches to Standby mode. The tray advanc-
es slightly so as to close the retaining bar, and the display shows the date and time. The analyzer resumes Ready-to-Meas-
ure status when the START button is pressed.

BIOHAZARD: Always wear protective gloves when handling and disposing of samples of
human origin.
The Urisys 1100 system is ready to read when the display shows a sample number and "INSERT STRIP !".
