2. Read off and note down the fill volume V
1
(e.g.
300 ml).
3. Place the suction hose in the measuring beaker.
4. Start the calibration process in the "
Setup
>
Calibration
" menu.
5. The pump executes 200 dosing strokes and
displays the factory calibration value (e.g.
125 ml).
6. Remove the suction hose from the measuring
beaker and check the remaining volume V
2
(e.g.
170 ml).
7. From V
1
and V
2
, calculate the actual dosed
volume V
d
= V
1
- V
2
(e.g. 300 ml - 170 ml = 130 ml).
8. Set and apply V
d
in the calibration menu.
• The pump is calibrated.
V
2
= 170 ml
V
d
= V
1
- V
2
= 130 ml
V
1
= 300 ml
