2.4 Errors
Errors can be generated by the user and/or the system itself. The analyzer
displays error messages and warnings in the display. If the printer has been
activated these messages will be printed.
2.4.1 Application errors
Application errors may cause error messages. Possible causes are:
- Air bubbles were created during pipetting
- Pipetting was performed directly into the measuring channel without
cuvette
- The wrong pipette tips were used
- The pipetted volume is incorrect (for variable Pipets)
- The pipetting process was too slow and the angle incorrect
- The temperature of the start reagent deviates from 37°C
- The reagent has been placed incorrectly
- The sample or control is too old
- No stir bar has been placed into the cuvette
- Reagents have been carried over (PT or Fibrinogen reagent)
- A reagent with the wrong lot number has been used
Should any of these errors occur and they are recognized in time, they must
be remedied immediately.
Certain of these errors can only be recognized when determining control
plasmas.
As a result we recommend running control plasma on a daily basis prior to
running routine determinations.
Cancel incubation / measurement:
By pressing the
Reset -key, any process on the measuring channel can be
cancelled.
