Standby mode. The error message is displayed again when the START button is pressed. In the event that the instrument is
defective, contact your local Roche Diagnostics representative.
E REFERENCE PAD ERROR
MIDDLE!
Cause: The middle portion of the reference pad on the test strip tray is soiled or
damaged.
Action: Switch off the instrument. Carefully clean and dry the pad. Check if it is
damaged (e.g. scratched, etc.). Insert the test strip tray again, then wait for the self
check to finish. If the error message is repeated, replace the reference pad or use
the spare test strip tray. Recalibrate with Control-Test M.
E REFERENCE PAD ERROR

Combur
Test
®

E STRIP MEASUREMENT ERROR ! Causes: No test strip is present on the test strip tray, or the strip is incorrectly
positioned on the test strip 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 calibration with a new calibration
strip taken from the Control-Test M container. Ensure that the strip is properly
positioned under the clip on the test strip tray (see Section ).
E CALIBRATION INVALID ! Cause: Calibration values are out of tolerance.
Action: Check the reference pad for soiling or damage. Clean if necessary (see
Section .) or use the spare test strip tray. Repeat the calibration with a new
Control-Test M calibration strip (see Section ). If the error message appears
again, the instrument is defective.

of the analyzer underneath the printer
cover (see Figure ) is missing, is not
making contact, is defective or contains
an old soft ware version.
