CX10/CX10+ D07-00-036 Rev.B01

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.

CX10/CX10+ D07-00-036 Rev.B01 5

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.

CX10/CX10+ D07-00-036 Rev.B018

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

BNC

• 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
