Reference method
Units shall be at the same
location for references
Each unit is performing its
own IL reference, and
units are connected using
two jumpers and a bulk-
head adapter.
Most accurate setup, but
both units must be at the
same location for refer-
ences.
Once the reference is
performed, do not discon-
nect jumper from units

Easy process.
Once the reference is

Use of non reflective
