the bevels into consideration. Insert the cover, having the flat side
directed toward the instrument's front.
4. Put in the lock washers and screw the cap nut into the optical bench.
Screw tight the cap nut by hand.
Tightening the cap nut too weakly can result in leakage of the
measurement cell. Tightening the cap nut too tightly can lead to a
direct contact of the capillaries to the cell, resulting in damage to
the cell.
