'Dosing profile' - 'Discharge optimized' , the pressure stroke is elon‐

gated and the suction stroke is executed as quickly as possible. This set‐
ting is suitable, among other things, for applications that require optimum
mixing ratios and chemical mixing that is as continuous as possible.
'Dosing profile' - 'Suction optimized' , the suction stroke is elon‐
Under
gated as much as possible, which makes it possible to meter viscous or
outgassing media precisely and problem-free. Select this setting to mini‐
mise the NPSH value as well.
With 'Dosing profile' - 'standard' the pump meters as usual.

Accuracy of calibration
Normally the pump does not have to be calibrated.
The pump can be calibrated if viscous feed chemicals
are used or extremely high accuracy is required.
WARNING!
If the feed chemical is hazardous, take appropriate
safety precautions when performing the following cali‐
bration instructions. Observe the material safety data
sheet for the feed chemical!

check whether litres or gallons have been selected.
2. If the incorrect volume unit has been selected, correct it in the
'Menu / Information è Settings è System è Unit' menu.
3. Check whether the stroke rate in the continuous display is not too
low for calibration.
4. Lead the suction hose into a measuring cylinder containing the feed
chemical – make sure that the discharge hose is installed perma‐
nently (operating pressure, ...!).
