Fill errors during sampling

After filling the sample into the pipette, the quality of the aspiration is checked by pre-measuring the pipette. The following parameters are checked:

• the column height
• the usage of diluent
• possible air bubbles

In case of air detection at the bottom of the pipette E20 Fill Error ! is shown on the display. This error indicates dilution problems or insufficient sample flow.

If there are other deviations, a beep will sound after the check and an ESR Error or warning is reported.
