Unpacking
Check carefully to see that all the components are received with no concealed damage.
1 Base, VS-2, with 2 Leveling Screws, VS-3, packed in a cardboard carton
1 Upright Rod, VS-34, with attached Clamp Assembly, VS-35Y
Assembly (Refer to Figure H1)
1. Remove the base assembly from the carton.
2. Remove the screw and washer from the upright rod. Place the rod and clamp assembly into the hole
in the top of the base.
Note: The “Front” designation on the clamp assembly should face the
opening of the legs, i.e., parallel to the leveling feet.
3. Rotate the rod/clamp assembly slightly until the slot on the bottom of the rod intersects the pin
located in the base.
4. While holding the rod and base together, insert the slotted screw and washer as shown and tighten
securely.
Viscometer Mounting
Insert the Viscometer mounting rod into the hole (with the cut-away slot) in the clamp assembly. Adjust
the instrument level until the bubble is centered from right to left and tighten the clamp knob
(clockwise). Use the leveling screws to “fine” adjust the viscometer level. Note: If the Digital
Viscometer cannot be leveled, check to insure that the rod is installed with the gear rack facing
forward.
Note: If the clamp is taken off the upright rod, the tension insert (Part No. VS-29) must be
properly aligned for the clamp to fit back onto the upright rod. When the tension
insert (Part No. VS-29) is inserted, its slot must be in the vertical position parallel to
the upright rod. If the slot is not in the correct position, the clamp will not slide down
over the upright rod. Use a small screwdriver or pencil to move it into the correct
position. The VS-29W Belleville spring washers must face each other as illustrated.
Adjust the VS-28 tension screw so that the clamp assembly is not loose on the upright
rod.
Caution: Do not tighten the clamp knob unless the viscometer mounting rod is
inserted in the clamp assembly.
Center the Viscometer relative to the stand base and retighten the jam nut as required. Referring to the
Viscometer bubble level, adjust the leveling screws until the instrument is level.
