Testing with Digital Multimeters and Cable Testers

Use a digital multimeter to measure parameters such as AC and DC voltage, current, resistance,
capacitance, cable continuity. Use cable testers, also, to verify physical connectivity.
Use cable testers (scanners) to check physical connectivity. Cable testers are available for shielded
twisted pair (STP), unshielded twisted pair (UTP), 10BaseT, and coaxial and twinax cables. A given
cable tester might be able to perform any of the following functions:

Test and report on cable conditions, including near-end crosstalk (NEXT), attenuation, and noise.
Perform time domain reflectometer (TDR), traffic monitoring, and wire map functions.
Display Media Access Control (MAC) layer information about LAN traffic, provide statistics such
as network utilization and packet error rates, and perform limited protocol testing (for example,
TCP/IP tests such as ping).
