4.2 Setting the volume

The possible dispensing volumes are listed in tables. These are found un-
der the transparent clip on the back of the instrument.
9 half-stroke positions can be set, from 1 to 5.
a.
Search for the desired dispensing volume (volume) in the table.
b.
Use the stroke setting dial to set the stroke number for the volume
that corresponds to the PD-Tip (tip size).
c.
Dispensing steps: depending on the PD-Tip used, the same volume
can be dispensed in a varying number of steps. The smaller the num-
ber of steps, the higher the accuracy of the dispensed volume.
Example:
Desired dispensing volume per step: 200 µl
PD-Tip size used:
2.5 ml = stroke setting 4 = max. 11 dispensing steps
5 ml = stroke setting 2 = max. 24 dispensing steps
10 ml = stroke setting 1 = max. 49 dispensing steps
