2.3 AutoZero
The DVPlus Viscometer must perform an AutoZero prior to making viscosity measurements. This process sets the
zero reading for the measurement system. The AutoZero will be performed every time the instrument is turned on. It
is not necessary to perform an AutoZero before each test.
Proper AutoZero function requires that the Viscometer be level (see Section 2.2) and that the spindle be removed
from the coupling shaft. Additionally, any spindle coupling, or extension links used with accessory devices should
be removed from the coupling shaft. The DVPlus display presents a reminder screen to remove the spindle. The
operator must press the Run button (see Figure 2-3.1) to initiate the AutoZero. (Figure 2-3.2) Once finished, the
DVPlus presents a message that the AutoZero has completed. (Figure 2-3.3) The operator must press the OK button
