1. Product Introduction
The CX10/CX10+ is a handheld Cable Length Meter that
employs Fast-Edge Step Time Domain Reectometer (TDR)
technology to measure the length of power and telecom
cables. The unit is able to measure cable length, including
the distance to open or short circuit faults up to a range of
2000 meters (6000 feet).
Fast-Edge Step TDR technology measures cable length and
locate opens and shorts, with improved range and resolution.
Results are displayed directly on an alphanumeric LCD.
The units also incorporate an oscillating tone generator to
trace and identify pairs within a cable bundle using industry
standard tone probes.
An internal library of standard cable types enables accurate
distance measurement without having to enter the Velocity of
Propagation (Vp) values beforehand, while automatic cable
impedance compensation is another time saving feature.
In the event the CX10/CX10+ is connected to a live cable,
testing is suspended and audible and visual alarms alert
the user.
If the units are is accidentally connected to a cable carrying a
voltage greater than 10 Volts, a warning tone will be emitted
and a “Voltage Detected” message will be displayed. This is
a great Safety Feature protecting the technician in potentially
hazardous working conditions.
A shutdown feature automatically turns the unit off after four
minutes of inactivity, preserving battery life.

1.1 Principles of Operation
The TDR works on the same principle as radar, where a
pulse of energy is transmitted down a cable. When the pulse
reaches a fault or the end of the cable, a portion or all of the
pulse energy is reected back to the instrument.
The TDR measures the time it takes for the signal to travel
down the cable, detect the problem, and to reect back. The
TDR then converts this time to distance and displays the
information as a waveform and/or distance reading.
The CX10/CX10+ works by measuring the time taken for a
signal to travel to the far end of the cable under test, or to
an intermediate fault, and return.
The velocity at which the signal travels (Vp - Velocity of
Propagation) will depend on the characteristics of the cable.
2. Safety Information
Safety precautions should be observed during all phases
of operation of this instrument. The instrument has been
designed to ensure safe operation, however, please observe
all safety markings and instructions.

CX10/CX10+ D07-00-036 Rev.B016
Voltage Safety Warning: If the CX10/CX10+
is accidentally connected to a cable carrying a voltage greater than
approximately 10V, a warning tone will be emitted and the instrument
display will show “Voltage Detected”. Testing will be inhibited and
the operator should immediately disconnect the unit from the cable.
The CX10/CX10+ has been manufactured in accordance
with and meets the requirements of the following standards:
• SAFETY IEC 61010-1 and EN 60950
• EMC BS/EN 61326-1
• EMC EN50081 and EN50082 Light Industrial
• Water/Dustproof to IP54
3. Basic Operation
3.1 Keypad
The unit is powered on and off from the red key on the
keyboard area. In order to turn off the unit, press the power
key for at least 2 seconds. If the unit is not responding,
holding the power key down by more than 10 seconds will
force the unit to power down.
The keypad comprises the
following keys:
 LCD display
 Navigation down/up
 Toggle key
 TDR
 Power On/Off

CX10/CX10+ D07-00-036 Rev.B01 7
3.2 LCD Display
The CX10/CX10+ is equipped with a 2x16 digit alpha-
numeric LCD display. Upon power up, the screen will display:
• Model #
• Software version programmed into the unit
• Last cable type tested
• Last Vp setting
• Battery status indicator - An all black battery
indicates fully charged condition, however as the
battery discharges, the indicator changes to white
3.3 Settings
The following can be set according to user preference:
Measurement units, Language, Library, and Contrast.

To change the settings:
• Hold down the TDR key and press the key
• Pressing the key will now toggle between the
settings
• Press the and arrow keys to change the
options for each setting

3.4 Battery
The CX10/CX10+ operates from 6 Volts provided by 4x1.5
Volt Alkaline batteries (AA) located in the rear of the unit. The
battery life is 100 hours of continuous scanning. To preserve
battery life, the units are tted with an auto shutdown feature.
Four minutes after the last key press, the auto shutdown
feature turns the unit off automatically. To replace the
batteries, follow the procedure below:
1. Disconnect the instrument from cable under test
2. Turn the instrument off
3. Loosen the two black screws and remove the
battery compartment cover
4. Replace the batteries with four 1.5 Volt Alkaline
batteries (AA size), observing the polarity markings
5. Ret the battery compartment cover and the two
cover screws
3.5 Connectors
The unit can be equipped with Banana jacks or BNC
connector types.
2x 4mm Banana

• Ensure no power supply or
equipment is attached to the
cable under test
• Ensure the far end of the cable
under test is open or shorted
(not tted with a resistive
termination)
• Voltage protection up to 250
Volts AC

4. Operation
4.1 Selecting a Library Cable or Setting Vp
After switching on the CX10/CX10+ and viewing the version
and battery life information, the display will show the last
cable type tested and/or the last Vp setting.
Press the and arrow keys to move through the cable
library. If the cable to be tested is not listed, or a different
Vp is required, continue pressing the up arrow key, past the
top of the library, where Vp settings between 1% and 99%
can then be selected.
When the units are turned off, the last cable library or Vp
setting will be remembered. This feature is useful in the
situation where the cable operator is performing many tests
on the same type of cable, as is generally the case.
Note: Determining unknown Vp values
If the CX10/CX10+ is to be used with a cable type for which the Vp
is unknown, this value must rst be determined:
1. Take a sample of the cable at least 20m (60ft) long
2. Measure the actual length of cable using a rule or tape
measure or some other reliable method
3. Connect the CX10/+ and adjust the Vp setting until the test
give a correct reading of the sample length
