Be careful not to break the sapphire jewel within the Microsyn housing
when performing step 11.
11. Carefully slide the Microsyn housing off the center wire of the
torsion element.
12. Clean and inspect the center wire as follows:
a. Using contact cleaner or other non-residue cleaner, gently
clean the length of the center wire.
b. Inspect the surface of the center wire that contacts the jewel.
If this area is scored, viscometer reproducibility problems
may occur. Refer to Appendix A and contact Brookfield
