5. Calibration

ATTENTION: The following statements only need to be observed when the Urisys 1100 system is used in

conjunction with Combur
The Urisys 1100 system is calibrated before leaving the factory. When installed, it must be recalibrated with Control-Test M
calibration strips before the first samples are read, and thereafter every seven days. Control-Test M calibration strips consist
of a grey plastic material that is standardized to give constant, defined reflectance readings. The purpose of calibrating the
analyzer is to compensate for aging effects that influence the optical system and the grey reference pad in the strip tray. 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 below).
When the Urisys 1100 system is set to Combur
This is why, when the instrument is installed, the "REPEAT CALIBRATION!" message is displayed following the successful
self check and also one week after the latest valid calibration.
Press the left function key ("Yes") to read the "START CALIBRATION!" message.
Procedure
1. Remove a calibration strip from the Control-Test M container. Be careful not to touch the pads and do not allow them to
come into contact with urine.
2. Place the calibration strip, with the test pads facing upwards, on the tray so that its leading edge is held by the clip at
the front end of the insertion slot. The retaining bar must be open (see Figures 6 and 7). Before calibrating, ensure
that the tray is clean and dry.
ATTENTION: It is very important that the calibration test strip locks into the instrument correctly in order
!
to ensure the quality of the calibration.
3. Press the START button. An acknowledging beep sounds. The tray advances slightly, the retaining bar closes, and the
grey reference pad on the tray and the calibration pads are read.
4. The tray is then transported back to the start position, and the retaining bar opens. Remove and dispose of the calibra-
tion strip. Use each calibration strip once only.
5. If the calibration is valid, the result is stored together with the date and time, and printed (see figure 8). Remove the test
strip and discard properly (follow test strip insert instructions).
CAUTION: Regular calibration is necessary to ensure the quality of the results obtained.
!
Roche Diagnostics cannot warrant the correctness of results if the system is not calibrated regularly.
ATTENTION: You can recalibrate the system at any time, even if a week has not elapsed since the last
calibration, for example if a Combur
!
tion procedure by pressing the left function key ("Calibr. " ) with the analyzer in Ready-to-Measure mode.
The message "START CALIBRATION !" appears. Follow the calibration procedure described page 36.
ATTENTION: If you reply with "No" to the weekly "REPEAT CALIBRATION !" reminder, for example be-
cause you have used up your supply of Control-Test M calibration strips, the message "Repeat calibra-
!
tion" is printed together with each patient report from subsequent readings. Obtain a new pack of Control-
Test M and recalibrate immediately.
