stirring rod. The slurry should not be drawn up from the bottom of the bottle but from
the middle of the filling quantity. Clean the outside of the pipette. Then place the
pipette into the holder.
Abrasion slurry once taken from the bottle should not be put back.

Test execution
Be sure that you have followed all test preparation instructions.
3.1
Adjusting the specimen
The vice with the clamped specimen can be moved in x-y-direction. The optional laser
pointer facilitates the positioning of the specimen.
If a ball with a diameter of 30 mm is used and the surface of the probe has been
adjusted by means of the gauge, the laser pointer points to the spot on the surface of
the specimen where the ball will grind the spherical cap.
The laser pointer will be switched on automatically, when it has reached its final
position.
3.2
Application of the abrasive slurry (only manual application)
If the automatic dosage apparatus is not used, the abrasive slurry must be applied
manually before doing a test.
Each test requires only 1 drop (see figure) of abrasive
slurry. This applies to all indicated test durations.
Exert slight pressure on the rubber bulb until a drop of
slurry is formed. The drop should come off the pipette
by self-weight. This should ensure that the drops have
a constant mass. Take heed that there are no air
bubbles in the drop, otherwise the ball must be
cleaned and a new drop must be applied.
