Figure A4
Turn the adjustment ring to the right (counterclockwise as you look down on the instrument) in small
increments (one or two divisions of the ring) while watching the Rheometer % display (Figure A5).
Remember that you are trying to raise the cup so that the pin in the cone touches the pin in the cup. Once
you have found this hit point, you can "back off" to create the desired gap between cone and cup. You
must wait at least 6 seconds between movements of the ring. Turn the adjustment ring until the display
reading jumps from 0.0 to 0.4% (HA and HB models) or from 0.0 to 0.6% (RV models) or 0.0 to 1.0%
(LV models). This is the HIT POINT. The cup may have to be adjusted up and down several times before
this deflection is satisfactorily reached. The LV series DV-III Rheometer will be the most sensitive.
