Whether you're an electrical contractor, a home networking professional, datacom specialist or IT/network manager, the Fluke Networks MT-8200-49A MicroMapper Voice/Data/Voice (VDV) verification and troubleshooting tool will allow you to verify your work while delivering a quality installation. The MT820049A MicroMapper is a small handheld cable tester which enables network professionals to quickly and easily verify the integrity of Ethernet twisted pair cabling. The MicroMapper quickly and easily tests twisted pair cabling, giving you visibility of opens, shorts, crossed, reversed and split pairs. Just push the TEST button and MicroMapper will automatically scan all wire pairs for any existing faults in your cable. MicroMapper's built-in tone generator works with the IntelliTone Pro Probe or any other analog probe, allowing you to trace cable through walls, floors, and ceilings. The MicroMapper also includes a remote unit that allows one person to test installed cabling or patch cords.
