Calibration process - example for DDA 7.5 - 16
1. Fill a measuring beaker with dosing medium.
Recommended filling volumes:
2. Read off and note down the fill volume V
1
(e.g.300ml).
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.125ml).
6. Remove the suction hose from the measuring
beaker and check the remaining volume V
2
(e.g.170ml).
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.
