Cable/Network Tester
1.Introduction
• The Cable/Network Tester analyzes wiring on phone, computer network and coax cables in one
easy step.
• The large backlit LCD display maps out connections and describes wiring faults.
• The built-in tone generator and the included Video and Data remote identifiers can be used to
quickly locate cables in wiring closets and patch panels.
• In addition, we have added many practical functions, you can get the voltage on telephone wire
and the POE voltage, you also can locate a cable connection to a switch port by blinking the
switch’s Link LED and the tester will display the advertised speed of the port and the cable pairs
used to transmit.
• The Cable/Network Tester measure cable distance to open or short (TDR), and perform detailed
wire-mapping including Skew, Delay & Ohms.
• Measures network speed capabilities
• Store and print up to 250 Reports.
• With proper use, this tester will provide many years of reliable service.
2.Safety
WARNINGS
• Do not connect the tester to a live circuit, exposure to voltage can damage the tester.
• Do not modify or try to repair the tester, no serviceable parts are inside.
• Do not use the tester in a wet environment or during electrical storms.
• Do not use the tester near explosive gases, dust or vapor.
• Visually inspect an RJ plug before inserting it into the tester, poorly terminated plugs may damage
the jacks on the tester.

5.Operation
5-1.Length Test
1.Press the Power Button to turn tester on.
2.Connect one end of the cable to the appropriate port, located at the top of the main tester body,
leave the other end of the cable unterminated.
3.Select the Length icon “ ” below the test cable and press the OK Button to enter Length
mode.
4.Press the Up Button and the Down Button repeatedly to select the pair of wires that should be
measured, the first functional pair is chosen by default.
5.Press the Left or Right Buttons to switch units (feet and meters).
6.Read the length measurement as shown.
Note: A voice or data cable under test can be unterminated (open) or terminated by an RJ45 remote,
if it is terminated by the self-storing remote, the reading will be 1 to 2 ft. greater than the actual
measurement, in this case, subtract 1 to 2 ft. from the reading to obtain the actual measurement.
• When you move the cursor to the Length icon for each of the cable types, you can see the VOP
value, VOP (Velocity of Propagation) is typically represented as a percentage of the speed of light,
as an example, a VOP of 67% means the velocity of the cable is 67% of the speed of light, the
VOP value is the foundation of length measurement accuracy.
• There are two ways to change the VOP value, each cable type has its own VOP, use the VOP
Adjustment Knob icon (to the right of the Length icon) to set the length constant based on a
known value (for example, as given by the cable manufacturer) (use the VOP icon) or let the unit
determine the VOP of your cable by connecting a sample of the cable to the unit(use the CAL i
con).
• Adjust manually (“VOP”) or Calibrate (“CAL”) the tester from a known length of cable (no remote
connected), minimum length required 100” (35m), use the Left/Right arrows to select method
you want, use the Up/Down to change the value, when you use the CAL icon, you can use the Left/
Right arrows to change the value added each time, finally you can press the OK Button to save
the VOP value that you set.

5-2.Cable Test
1.Press the Power Button to turn tester on.
2.Connect one end of the cable to the appropriate port, located at the top of the main tester body,
connect the other end of the cable to the corresponding port on the remote.
3.Select the Cable Test icon “ ” below the test cable and press the OK Button to start the test.
4.Then the test result will display: Pass/Fail, Wire map, Opens, Shorts, Split Pairs, the min length
of the cable, when both ends of the tested network cable are connected with shielding, “S” is
displayed.
5.When the Details glass lit, press the DETAIL Button and use down arrow to show more results,
press the OK Button to save the data for this measurement.
6.Press the EXIT button when done.
5-3.RLQ Test
• Return Loss Quality tests for load mismatches that affect the wire’s power and data transfer
capability.
• It is a powerful quality test that should be used if quality problems are suspected with the cable.
• The RLQ test works with DATA cables and VIDEO cables.
1.Connect cable to Main unit and green RLQ Remote.
2.Select and start Test APP “ ”.
3.View test results, the result is displayed as a single integer of 0, 1, or 2, “0” indicates the cable
measures as if it is unterminated, “2” indicates it is perfectly terminated, Quality issues can
arise in a transmission cable (Cat5/6 or coax) for a variety of reasons, including physical damage
caused by crushing or bending the cable too sharply, improper termination, moisture intrusion,
etc.
5-4.Phone Devices Test
Use: Detect central office telephone connections (48V), display voltage and cable location.
1.Connect the cable to the RJ11/RJ12 connector on the unit.
2.Select the Telephone APP “ ” and start the test.
Result: The unit scans the 6 pins and displays up to 3 pairs of central office connections; the
pairs used (typically 3,4; 2,5; and 1,6); and the amplitude of voltage on each pair.
