3.2.5. Diluting
In Dilution mode liquids separated by an air gap are aspirated and then
dispensed simultaneously. Diluting can be used to dilute samples and reagents.
The diluent is aspirated first followed by an air gap, then the sample or
reagent to avoid contamination.

1. Select MENU by pressing the left Softkey.
2. Use the adjustment wheel to select Diluting and confirm by pressing the
operating button or the right Softkey for OK.
To edit the volume and speed settings:
1. Press the middle Softkey for EDIT or turn the adjustment wheel all the way
to the right or left. The first setting to be edited is now highlighted.

5. To exit the editing mode without saving changes, press the left Softkey for
BACK.
To use the pipette with the selected program:
1. Press the operating button to aspirate the diluent.
2. Press the operating button again to aspirate the air gap.
3. Press the operating button a third time to aspirate the sample.
