CHAPTER 3: Operation
2. Press the CABLE button to turn on the tester.
Press the CABLE button again until Cable Length
is displayed, then press the SEL button. To change
length units between feet and meters, press the
SETUP button.
3. Press the up/down arrows to adjust the length
constant (a known length of cable that you will use
as a reference). If the length constant is unknown
for a particular cable, you can use a known length
of cable to set the constant. The known cable
should be 50 ft. (15.2 m) or longer to minimize
the resolution error. Connect the known length of
cable to the tester and change the cable constant
using the up/down arrows until the length reads
correctly.
3.5 To Locate an Ethernet Port
1. With the LAN Solution Network Tester powered
off, connect the tester to a jack or plug at the
workstation location for which the Ethernet port is
to be located.
2. Press the NTWRK button. The tester will power up
in the Flash Link LED mode and connect to the
Ethernet port on a hub, switch, or NIC. Even if no
connection is made, tone is generated on the
cable to help find the cable with a tone tracer at
the other end (in the equipment closet).
