Setting The Volume; Important - BrandTech HandyStep S Mode D'emploi

The possible dispensing volumes of the HandyStep
These are found beneath the transparent clip on the backside of the
instrument.
There are 9 half-integral stroke setting positions, from 1 to 5.
1.
Look for the desired dispensing volume (Volume) in the table.
2.
Use the stroke setting wheel to set to the proper stroke number
(Setting) for the volume that corresponds to the PD-Tip (Tip size).
3.
Dispensing steps: depending on the PD-Tip capacity (ml), the same
desired dispensing volume per step can be delivered a different
number of times (see example below). The smaller the number of
steps, the higher the accuracy of the dispensed volume.
Example:

Important!

Desired dispensing volume per step: 200 µl
PD-Tip sizes to use:
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
The volumes listed in the table are the only options avail-
able. Since the first dispensing step must be discarded,
the number given in the table is always 1 step less.
