Resistive Balance Test
Summary
The Resistive Balance test is a reliable way to understand pair balance
using resistance measurements and a far end strap. Compared to regular
resistance tests, Resistive Balance isolates the resistance of each
conductor (leg) which should ideally be the same within 5%; if not, and if
there are no other metallic faults (for example, a ground/earth fault), then a
highly resistive (HR) fault may be present. An HR can otherwise be very
difficult to identify. Use Pair Detective or TDR or RFL to locate the HR.
Summary tab displays the pass/fail status of the tests executed. Refer
Copper Tests: Result Summary on page 291 for more information.
