Multimeter

You are installing networking wiring for a new Ethernet network at your company's main office building. The project specifications call for Cat 5e UTP network cabling and RJ45 wall jacks. Near the end of the project, you run out of wire before the last few runs are complete. You have a spool of Cat 3 network cable in storage.
