Which testing device verifies a wire map?

A pair scanner is specifically designed to verify a wire map by checking the connectivity and pairing of twisted pairs in a cable. This device confirms that each conductor within the cable is correctly terminated and that there are no miswirings or opens. It can identify if pairs are crossed or if any wires are incorrectly connected, ensuring that the cable will perform properly in a network.

A tone generator is used primarily for tracing and identifying cables but does not provide capability for checking the wire map. A signal meter typically measures the quality and strength of a signal rather than the physical wiring arrangement. A multimeter is a versatile tool for measuring voltage, current, and resistance, but it does not provide a comprehensive analysis of the wire map itself. Thus, the pair scanner is the best fit for confirming the integrity and mapping of wire connections within a cable.
