Conductive Mode requires which setup?

• A. Only using inductive coupling
• B. Attaching cables from terminal posts to the conductor and a grounding source
• C. Reading from a handheld wand only
• D. Placing a magnet near the conduit

Answer: (B)

Conductive mode relies on creating a complete electrical path along the target conductor so the receiver can detect the signal flowing in the line. This requires a direct connection to the conductor and a grounding return to complete the circuit. Attaching cables from terminal posts to the conductor and to a grounding source provides that necessary setup, allowing the transmitter to energize the line and the receiver to sense the current path. Inductive coupling uses the magnetic field around the conductor and does not require a direct connection; reading with a handheld wand alone doesn’t establish the energized path; and placing a magnet near the conduit isn’t how conductive mode is performed.
