Test Details
Voltage Checks
This test checks for a voltage in excess of a few volts DC across each pair. If a voltage
is detected above this threshold, then testing will be inhibited.
Wiremap
This test checks the cable for correct wiring when the remote unit is connected to the
end of the cable under test. The cable configuration is tested for shield continuity (if
fitted), opens, shorts, reversed pairs, crossed pairs, and split pairs. Below are examples
of detectable faults along with a good wiremap.
