4.2-4 Section 4: Using the Model 9100: Interconnections
Final Width = 215mm
4.2.4 Lead Types when the 9105 is not Used
If it is decided not to use the 9105, reductions in the degradation of specification can still be achieved, using appropriate connections
on short leads of the correct type. To assist in this, Fig. 4.2.3 shows the internal connections in the 9105, and the cross section of
the 9105 main cable shows how the leads are laid out. The lead types are also described.
