1. Insert the pin of the mounting tool into the cover plate, and break
it off with a rotating motion (Fig. 2). Discard the adjustment cover.
2. Insert the pin of the mounting tool into the adjustment screw
(Fig. 3) and rotate to the left in order to increase the dispensing
volume, or rotate to the right to decrease the dispensing volume
(e.g. for an actual value of 9.97 ml, rotate approx. 1/2 turn to the
left).
3. The change in the adjustment is indicated by a red disk (Fig. 4).

After a long period of usage an adjustment of the instrument might
be necessary.
- Calibrate for example at nominal volume (see page 38).
- Calculate mean volume (result of weighing) (see page 38).
- Adjust the instrument (to the calculated mean volume).
- After the adjustment, further calibration is necessary to confirm
appropiate adjustment.
Example:
The gravimetric check gives an actual value of 9.90 ml for a 10 ml
instrument set for a nominal volume of 10.00 ml.
