What effect has a rinsing process with Mode " Prepare compo-
nents "?
Air bubbles are removed by rinsing Dosino(s) and
component tubing (from the activated Components)
(see section 3.4.2).
When should a rinsing process with Modus " Prepare components "
be carried out?
We recommend that such a rinsing process is carried
out at least once per day, as well as each time that a
new Component has been added. Removal of air
bubbles increases the mixing accuracy.
How is a rinsing process with Modus " Prepare components " trig-
gered?
1. Configure: in the RINSE window set the parameter Mode
to Prepare components . Select the Components to be
"prepared".
2. Start: the rinsing process is started in the Main Win-
dow by clicking on the button.
How does a rinsing process with Modus " Prepare components "
proceed?
1. The cylinder(s) of the Dosino(s) is/are completely emp-
tied.
If in the RINSE window the parameter Economy is ac-
tivated then the Dosino contents will be ejected into
the component container of the
Main Component.
2. From each of the activated Components 10 mL will be
drawn in and ejected in succession.
3. At the end the Dosino(s) will be refilled with the Main
Component.
