II. GETTING STARTED
II.1 Autozero
Before readings may be taken, the Viscometer must be Autozeroed. This action is performed each
time the power switch is turned on. The display window on the Viscometer will guide you through
the procedure as follows:
Turn the power switch (located on the rear panel) to the ON position. This will result in the screen
display shown in Figure 3. The viscosity measurement range is indicated by the information in the
lower left, in this case RV. For most DV-II+ Viscometers, this information will be either “LV” or
“RV”.
