a. keep the liquid sample tightly sealed.
b. eliminate the formation of air bubbles.
c. avoid a build up of pressure
5. Mounted on the lower and upper plates are inlet/outlet ports (10a and 10b) for connection
to the water bath.
NOTE: Any alteration, modification or replacement of the sample tube, water jacket,
falling tube screw fittings, tension rods or balls renders the ball constants invalid
and requires the re-calibration of the viscometer. See Appendix B.
6. The thermometer screw (11) and thermometer seal (13) with inserted thermometer is screwed
into M10x1 Thermometer attachment thread (12) in the upper plate. The thermometer screw
should be tightened securely to prevent fluid leakage.
7. The primary function of the ball gauge is to distinguish the two glass balls (Ball No. 1 and
Ball No. 2) from each other. Ball No. 1 will not pass through the ball gauge, whereas Ball
No. 2 will pass through. The ball gauge may also be used to help identify Ball No. 2 through
4.
