6. Install the test strip tray by holding the tray opposite the end with the gray reference pad and inserting the tray into the
slot below the function keys.
ATTENTION: Be careful not to touch the gray reference pad. Contamination of the reference pad may impair the quality of
the results obtained.
7. If you wish to proceed with the next readings directly after cleaning the test strip tray, switch the analyzer on again.
During the self check, the system will verify that the reference pad is in good condition for reading and that the
positioning hole in the test strip tray (see Figure 17) is free. If not, an error message will be displayed (see Section 8).
8. Error Messages and Troubleshooting
Error messages are shown in the display but are not printed out. Following five minutes of inactivity, the analyzer switches
to Standby mode. The error message is displayed again when the START button is pressed. In the event that the instrument
is not operating properly, contact Roche Diagnostics Technical Service at 1-800-428-4674.
E1 REFERENCE PAD ERROR Cause: The middle portion of the reference pad on the tray is soiled or damaged.
MIDDLE! Action: Switch off the instrument. Carefully clean and dry the pad. Check if it is
damaged (e.g. scratched, etc.). Insert the tray again, then wait for the self check
to finish. If the error message appears again, contact Roche Diagnostics
Technical Service at 1-800-428-4674. Recalibrate with Chemstrip Calibration Strip
(when using Chemstrip 10 MD*).
E15 REFERENCE PAD ERROR Cause: The bottom portion of the reference pad on the tray is soiled or damaged.
BOTTOM! Action: see E1
E16 REFERENCE PAD ERROR TOP! Cause: The top portion of the reference pad on the tray is soiled or damaged.
Action: see E1
E2 WRONG STRIP ! Cause: The test strip used is different from the one for which the analyzer has
been programmed (e.g. “Chem 10” test strip, “Chem 5” test strip, “Chem 7” test
strip).
Action: Press the START button. Repeat the measurement with the type of strip
for which the analyzer has been programmed.
E3 STRIP MEASUREMENT ERROR ! Cause: No test strip is present on the tray, or the strip is incorrectly positioned on
the tray, the urine on the test strip has dried, the test strip has not been dipped in
urine.
Action: Press the START button. Repeat the measurement with a new test strip.
Ensure that all test pads are dipped in the urine sample. Insert the strip correctly
and ensure that the retaining bar is closed properly after START button is
pressed.
E4 CALIBRATION ERROR ! Cause: Calibration values differ from those obtained in the last valid calibration.
Action: Press the START button. Repeat the calibration with a new calibration
strip taken from the Chemstrip Calibration Strip container. Ensure that the strip is
properly positioned under the clip at the end of the test strip tray (see Section 5).
E5 CALIBRATION INVALID ! Cause: Calibration values are out of tolerance.
Action: Check the reference pad for soiling or damage. Clean if necessary (see
Section 7.1). Repeat the calibration with a new Chemstrip Calibration Strip (see
Section 5). If the error message appears again, contact Roche Diagnostics
Technical Service at 1-800-428-4674.
