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. (Note: If cable DVP-80 is connected for printer or
computer communication see section II.9). 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 II-1 indicating that the DV-II+Pro viscometer is in the
standalone mode (is not connected to a computer).

After a few seconds, the following screen appears indicating the version of the operating
rmware (the built in program which controls the instrument) and a two-digit alphanumeric
code which indicates the Model number (see Table D2 in Appendix D; the code tells the spring
torque rating or the viscosity measurement range of your viscometer). For most DV-II+Pro
Viscometers, this information will be either “LV”, “RV” or “HB”:
