5. OPERATING INSTRUCTIONS

Preliminary examination
!
Remove the Abbe Refractometer from the packing material and examine it carefully to
make sure no damage has occurred during shipping. If there is any damage, notify to your
dealer/forwarding agency.
!
Keep all packing material until you are sure that the instrument works correctly. All
defective items must be returned in the original packing together with any other supplied
accessories.

n 1 = n 2 x sen ( α−β ) = (sen φ x cos β - cos φ x sen β )
n 2 ²x sen² β = sen² i
n 2 ²x (1-cos² β ) = sen² i
