• T6 Torx driver, (8710-2548)
• Tweezers (8710-2460)

Procedure
Always wear clean gloves when working in the analyzer chamber to avoid
C A U T I O N
contamination.
Refer to the exploded parts view
on page 166 while using this procedure.
1 Assemble the five lenses inside the lens insulator. (See
5977B Series MSD Operating Manual
• Large (8650-0030)
• Small (8650-0029)
page 164.) The lens number is engraved into the outer circumference of
each lens.
a Starting with the entrance lens 1, set the lens into the end groove in the
lens insulator, and rotate the lens until you feel the ball seat into the
circular recess.
b Insert the next 4 lenses, in numerical order, into the lens insulator. The
lens chamber open end always faces the entrance lens 1. Rotate each lens
until you feel the ball seat into the circular recess.

It is easier to insert lens 5 on an angle because the lens stack at this
point makes the lens insulator less flexible.
