Pressing the MOTOR ON/OFF/ESCAPE key again immediately starts the DV-II+Pro running
at the last scrolled-to-speed. If you had been running at 12 RPM, pressed MOTOR ON/OFF/
ESCAPE and then re-started the DV-II+Pro by pressing MOTOR ON/OFF/ESCAPE once again,
you would again be running at 12 RPM. However, if while the motor was off you had scrolled
to a new speed of 0.5 RPM, pressing the MOTOR ON/OFF/ESCAPE key would start the DV-
II+Pro running at 0.5 RPM.
Note: During both spindle or speed selection and scrolling operations,
the DV-II+Pro will continue to calculate and display Viscometer
data as selected.

Viscosity (displayed in units of cP or mPa•s), Shear Stress and Shear Rate are displayed on the
left side of the top line. You may “step” through the three display options by pressing the
SELECT
DISPLAY
key. For example, the DV-II + Pro is currently displaying Viscosity in Figure II-11:
cP 123e3 20.1C
6.0RPM % 15.6
Figure II-11
If the viscosity value exceeds 99,999 scientific notation is used. In Figure II-10, the viscosity
value is 123,000 cP.
The first press of the SELECT DISPLAY key would display Shear Stress (SS) in Dynes/cm2 (or
Newtons/m2), see Figure II-12:
SS 29.0 20.1C
6.0RPM % 15.6
Figure II-12
If the shear stress value exceeds 99,999, scientific notation is used.
The next press of the SELECT DISPLAY key would display Shear Rate (SR) in 1/Sec (Figure
II-13).
