Choose Spindle:
There are two options for spindle selection. The first option is that the Wizard will recommend a spindle to be used
based on the torque range of your DVPlus and the Estimated Viscosity of your fluid.
The second option will allow a spindle to be selected by manually entering the spindle code (see Figure 2-12.5).

Once the desired spindle is selected, press the Next key to move on to the "Determine Speed" screen.
Determine Speed:
A message on the screen will alert the user that the DVPlus will run a test to determine the optimal measurement
parameters (see Figure 2-12.6). When Next is selected, the DVPlus will instruct the user to set up the sample and
recommended spindle (see Figure 2-12.7).

When Next is selected, the DVPlus will then begin the first attempt at optimizing the speed & spindle combination. In
order to evaluate the spindle/speed combination, the DVPlus will run a viscosity test at a standard RPM with a torque
stabilization end condition of 50% with a tolerance of +/- 0.5% and a one-minute time period for the stabilization. The
goal of the Viscosity Wizard is to obtain the torque reading between 20% and 80%, ideally at 50%. Depending on the
setup, the time to complete the Viscosity Wizard test could be up to five minutes.
