Example measurements:
If the two wires are symmetric, i.e. identi-
cal in their mechanical properties,
a max. value is measured (in this exam-
ple >65 dB). Such a high value can only
be expected in ideal situations or in the
event of a short circuit between Tip and
Ring or an extremely short open line.
A value greater than 65 dB means that
the result is above the measuring range.
However, a value >40 dB (as in this
example 41.5 dB) is considered suffi-
ciently symmetric.
If a value <40 dB is measured, or even
7.8 dB as in this example, Tip or Ring
may be shorted to Ground.
