• MODE: The top line of the display shows what cable
type is being tested; voice (RJ11/RJ12) 1 , video
(F-terminated coax) 3 or data (RJ45) 5 , and if
Hub Blink mode or Tone mode is activated.

if the cable is a properly wired 4-pair T568A/B data
cable, a 3-pair one-to-one wired voice cable or a
video cable with no faults. In addition, 'X-over'
illuminates if a properly wired cross-over (uplink)
cable is recognised, or 'Rev' 8 illuminates if the
cable is a properly wired reverse-pinned voice cable.
The wire map will show actual pin connections.
'Shielded' 9 illuminates when a shielded data cable
is properly connected at both ends. It will be flashing
if there is a short to a wire in the cable, along with that
pin number and the 'Short' 11 indicator.
• CABLE FAULTS: 'Fail' 10 will illuminate only if the cable is not wired to one of the cabling standards.
See WIRING AND DISPLAY EXAMPLES section for wire standards and failure modes.
• VOLTAGE CHECK: A check for voltage on the RJ45 terminated data cable is performed before each test and
if found, no test is run. If voltage is detected on the phone, coax or data testing ports, or if voltage over 70
Volts is detected on the PoE testing port, the lightning bolt warning symbol
should be disconnected immediately from the source of the voltage.
• LENGTH: 15 Length of the cable run in feet or metres will be displayed here.
• LOCATION ID: 16 The remote ID number will be displayed here.
• BATTERY STATUS: The battery low icon

illuminate when the battery needs to be replaced. Results may be unreliable at this point.
• TESTER-END WIRE MAP: 18 Displays the pins on the tester end of the cable in order. These pins are mapped
to the pins on the remote-end shown directly below them on the LCD
• REMOTE-END WIRE MAP: 19 Displays the corresponding pin on the remote-end. Dashed lines on this row
indicate shorted pins. No pin numbers displayed on this row line are open pairs.
OPERATING INSTRUCTIONS
LENGTH MEASUREMENT: The VDV Scout Pro 3 uses the capacitive properties of a cable to measure its
TM
length. One end of the cable should be connected to the corresponding port on the top of the tester. The other
end should be left disconnected or attached to the self-storing remote.
LENGTH CONSTANT: The length constant refers to the electrical characteristic of a cable used to characterise
its length. Every cable has an associated length constant in units of picofarads per foot (pF/ft). Setting the length
constant on the tester is important for obtaining an accurate cable length measurement from the VDV Scout
3. The default length constants are as follows: Voice: 17.0 pF/ft
The length constant can sometimes be provided by the manufacturer of the cable (see DISPLAYING/EDITING LENGTH
CONSTANT section). You may have to determine the length constant yourself (see DETERMINING AN UNKNOWN
LENGTH CONSTANT section). Length constants can range from 10 pF/ft to 40 pF/ft.
Measurement accuracy is dependent on how close the tester can be set to the length constant of the cable being
measured and the consistency of the cable along its length.
The length constant can vary from cable to cable, even if it is of the same type, produced by the same manufacturer. It can
also vary over the length of one cable, because the length constant is dependent on the physical properties of the cable,
which may not be consistent throughout the entire cable. The change in wire-pair spacing through the cable can vary the
length constant along the length of the cable.
When setting the length constant using a length of cable, the cable should be at least 50' (15.2 m) long. This will yield a
±5% uncertainty (1 in 50) in the length constant accuracy. A longer cable reduces this uncertainty.
MEASURING LENGTH – VOICE OR DATA CABLES:
1. Press the Power button G to turn the tester on.
2. Connect one end of the cable to the appropriate port: RJ45 port
(if testing data cable) or RJ12 port (if testing voice cable), located at the top
of the main tester body. Leave the other end of the cable unterminated.
3. Press the Length button F to enter Length mode.
4. Press the Data button C or Voice button A
depending on the cable being tested, to begin the test.
5. Press the Data button repeatedly to select the pair of wires that
C
should be measured. The first functional pair is chosen by default.
6. Read the length measurement as shown.
MEASURING LENGTH – COAX CABLES:
1. Press the Power button G to turn the tester on.
2. Connect one end of the cable to the F-connector port
located at the top of the main tester body.
Leave the other end of the cable unterminated.
3. Press the Length button F to enter Length mode.
4. Press the Video button B to begin the test.
5. Read the length measurement as shown.

NOTE: A voice or data cable under test can be
unterminated (open) or terminated by an RJ45
ID remote. If it is terminated by the self-storing
remote, the reading will be 1' or 2' greater than
the actual measurement. In this case, subtract
1' or 2' from the reading to obtain the actual
measurement. The coax cable under test may
be left unterminated.

The length constant will be displayed with the word 'EDIT'. Use the UP
and DOWN buttons to increase or decrease the Length Constant value
C
in units of 0.1 pF/ft to the desired value. The decimal is not displayed, so for
example, '154' on the display means that the Length Constant is 15.4 pF/ft.
Length Constants are displayed in pF/ft or pF/m, depending on the selected
unit of measurement mode.
NOTE: The Length Constant can only be edited in the pF/ft mode. It is not editable in the pF/m mode.
NOTE: The Default for Length Constant edit for the Data cable is the wire pair of pins 1 and 2. If you wish to set
the Cable Length constant on wire pairs other than pins 1 and 2 of a data/RJ45 cable, follow Steps 1 through
3 above. Press the Length button
displayed. Press the Edit button
NOTE: The Default for Length Constant edit for the Voice cable is the wire pair of pins 3 and 4 of a voice cable.
If you wish to set the Cable Length constant on Wire pairs other than pins 3 and 4 of a voice cable, follow Steps
1 through 3 above. Press the Length button
edit is displayed. Press the Edit button
DETERMINING AN UNKNOWN LENGTH CONSTANT:
Follow these instructions to set the Length Constant based on a
sample cable of known length. For the best accuracy, the sample
cable should be 50 ft or longer. This example will use 50 ft.
1. Acquire a known length of cable at least 50 ft in length (50 ft in
this example) of the same type that you would like to measure.
2. Press the Power button
3. Follow the procedure in the MEASURING LENGTH section(s) to
set up the correct type of cable.
4. Press the Settings button
