2. GETTING STARTED
2.1 Power up
The DVPlus Viscometer will go through a Power Up sequence when the power is turned on. The Viscometer will
present a black screen for approximately 4 seconds and then the Splash screen for 5 seconds. The Splash screen is
shown below (Figure 2-1) and includes several critical parameters about the Viscometer including viscometer torque
(LV, RV, HA, HB, or other), serial number, and the firmware version number.
Note: A product registration screen appears the first 6 times the instrument is powered up, and again in 1 month.
Figure 2-1
The Splash screen information can also be accessed through the Main Menu, using the Technical Support Button.
(see Section 2.9)
If the DVPlus Viscometer is Level, it will automatically transition from the Splash screen to the AutoZero screen.
If it is not Level, then it will transition to the Adjust Level screen. (see Section 2.2)
2.2 Digital Leveling
Upon powering up the DVPlus, the user will be prompted to level the DVPlus device if not already level. To level the
DVPlus, adjust the leveling feet on the lab stand base. When the device is not level, the centering dot will be red.
While adjusting to a level position, the dot will become yellow, signifying that the device is approaching a position
where it will be level. Once the dot is within specified limits of the center circle, the dot will turn green to signify that
the DVPlus is now level and ready to operate (see Figures 2-2.1, 2-2.2, and 2-2.3 below). Following this process, the
device will then move onto the Auto Zero function (Section 2.2). Pressing the Skip button will trigger a message
warning the user that "Results may not be accurate" if the DVPlus is not level (Figure 2-2.4). It is recommended to let
the instrument warm up for 10 minutes before leveling. Recheck the level prior to running any tests, especially the
test with accessories and try to get the level as close as possible.
