Operation
Setting of the capacity / flow rate
For step motor pumps, the metering capacity is set by changing the metering stroke
duration with a constant suction stroke duration. The lower the metering capacity
that is set, the more the expression time is extended. For example, setting the
metering capacity to 50% doubles with expression time. When considered over a
fixed period (for example, one minute), this results in a halving of the metering
capacity.

Use the 'rotary button for setting the dosage quantity' to set the required litre
capacity / flow rate.
2.
Use a suitable screwdriver to tighten the locking mechanism and fix the rotary
button in place to exclude the risk of accidental adjustment.
Switch to metering mode
When working with liquids with high viscosity, cavitation (shearing of the fluid flow
in the intake tract) often occurs due to the very high friction forces that occur during
suction. This can be counteracted by extending the intake time and thus reducing
the friction torque.
If "Viscosity high" metering mode is selected, the pump speed is reduced by one
third and the suction time is extended accordingly. However, since the metering
stroke time is also extended in addition to the suction time, the maximum metering
capacity of the pump is reduced by one third.
