I.4 Operation
Viscometer and Stand
The instrumentation should be placed on a firm level surface near a 15 amp, 115 or 230 volt, 50 or
60 Hz grounded A.C. electrical service, as required. A cooling water supply and drain ar rangement
is also recommended for cooling the thermo-container with optional cooling plug assembly.
Set up the viscometer stand by connecting the upright rod with clamp attached into the base. Screw
the leveling screws into position on the base. (Refer to the assembly instruction supplied with your
lab stand.) Attach the vis cometer to the stand by inserting it into the clamp; level the viscometer
and position it centered between the stand legs. Raise the viscometer on the lab stand upright rod
so that there will be sufficient room to attach the alignment bracket. Check that the power switch
is OFF and plug the viscometer power cord into the appropriate electrical service.
Alignment Bracket
Attach the alignment bracket to the rear of the viscometer pivot cup, securing it tight with the
knurled screw. (Refer to Figure I-2).
Thermo-Container, Sample Chamber, Safety Guard
Using the three (3) leveling screws in the thermo-container base, to level the base.
Check that the perforated safety guard is flush onto the base of the thermo-container.
Using the extracting tool, insert the chamber into the thermo-container. Rotate the chamber until
it drops and locks in place prohibiting further rotation.
Controller and Probe
Set the controller on a level surface adjacent to the thermo-container. Insert the male plug (three-
prong) from the thermo-container braided cord into the socket on the back of the controller (turn
and lock connection). Insert the four-inch stainless steel probe (Resistance Thermometer) into the
hole in the thermo-container located directly above the braided cord. Plug the other end of the probe
into the connector located on the back of the controller. To remove the probe, depress the spring
clip and carefully slide probe out. This removal procedure should not be followed if the thermo-
container is at a temperature above 100°F (37°C). Cool the thermo-container first.
If the probe is not inserted in the thermo-container and the
controller is turned on, the thermo-container will cease to heat
and the controller will give an audible signal!
Set the controller power switch to the OFF position.
Plug the controller power cord into a 115V, 50/60 Hz or 230 V, 50/60 Hz grounded A.C. power
supply, as required.
System Alignment & Spindle Insertion
Looking down on the viscometer, level the stand base by adjusting the leveling screws until the
bubble is centered.
