3) Connect the RTD probe to the socket on the rear panel of the DV-II + Pro.
4) The Viscometer must be leveled. The level is adjusted using the two leveling screws on the
base. Adjust so that the bubble level on top of the DV-II + Pro is centered within the circle.
Note: Check level periodically during use.
5) Remove the shipping cap which secures the coupling nut on the Viscometer to the pivot
cup. For Cone/Plate Models, hold the Sample Cup and swing the tension bar away from the
bottom of the cup. Lower the cup and remove the foam insert. (Save for future shipments.)
6) Make sure that the AC power switch at the rear of the DV-II + Pro is in the OFF position.
Connect the power cord to the socket on the back panel of the instrument and plug it into
the appropriate AC line. For Cone/Plate Models, be sure that the toggle switch, used to set
the electrical gap, is to the left position. (Left when facing the viscometer keypad.)
The AC input voltage and frequency must be within the appropriate range as shown on
the nameplate of the viscometer. (See section I.2.)
Note: The DV-II+ Pro must be earth grounded to ensure against electronic failure!!
7) Turn the power switch to the ON position and allow the viscometer to warm up for 10
minutes before performing autozero.
8) For Cone/Plate models, refer to Appendix A.
9) If appropriate, connect interconnecting cable (DVP-80) to serial port for connection of
DV-II+Pro to PC or printer.
10) If appropriate, connect interconnecting cable to parallel port for connection of DV-II+Pro
to printer.
11) If appropriate, connect interconnecting cable (DVP-96Y) to analog (serial) port for
connection of DV-II+Pro to chart recorder.
