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 H-1)
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.
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 large slotted pan head screw as
required. Referring to the Viscometer bubble level, adjust the leveling screws until the instru-
ment is level.
