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 F-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.
YR-1 Rheometer Mounting
Insert the YR-1 Rheometer 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 “finely” adjust the viscometer level.
Note: If the Rheometer 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 YR-1 relative to the stand base and retighten the jam nut as required. Refer ring to
the Rheometer bubble level, adjust the leveling screws until the instrument is level.
