6.5.1 Calibration process - example for DDA 60-10
1. Fill a measuring beaker with dosing medium.
Recommended filling volumes V
1
:
– DDA 60-10: 2.5 l
– DDA 120-7: 5 l
– DDA 200-4: 8 l

2. Read off and note down the fill volume V
1
(e.g.
2.5 l).
3. Place the inlet line 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. 1.05 l).
6. Remove the inlet line from the measuring beaker
and check the remaining volume V
2
(e.g. 1.39 l).
7. From V
1
and V
2
, calculate the actual dosed
volume V
d
= V
1
- V
2
(e.g. 2.5 l - 1.39 l = 1.11 l).
8. Set and apply V
d
in the calibration menu.
• The pump is calibrated.
V
2
= 1.39 l
V
d
= V
1
- V
2
= 1.11 l
V
1
= 2.5 l
