Materials needed
Procedure
Always wear clean gloves when working in the analyzer chamber to avoid
C AU T I O N
contamination.
Refer to the exploded parts view and the EI HES parts list while using this
procedure. (See
Use care when inserting the lenses into the lens insulator casing. Putting
C AU T I O N
excessive stress on this casing can break or crack it. If this happens, do not
attempt to operate with a defective lens insulator, it must be replaced.
1 Assemble the five lenses inside the lens insulator. (See

number is engraved into the outer circumference of each lens.
a Starting with the extended 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 on the back of the lens insulator.
b Insert the next 4 lenses, in numerical order, into the lens insulator. The
lens chamber open end always faces the extended 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.
