This provisional adjustment explains how to adjust without using the network analyzer
as opposed to adjustment (Section 3-8-5) using the network analyzer.
Perform this provisional adjustment only when the network analyzer is not available for
an urgent maintenance. Be sure to perform the adjustment (Section 3-8-5) using the
network analyzer at a later date.
