1 ABOUT THE ELCOMETER 701

The Elcometer 701 Pipe and Cable Locator provides simple and user-friendly location, orientation

and depth of underground lines, such as cables and pipes, or the location of non-metallic pipes

using the optional sondea.

The Elcometer 701 can be used to search/probe areas for unknown lines or for locating specific lines.

The locator consists of two instruments; a transmitter (Tx) and a receiver (Rx).

Both instruments are constructed robustly for use in poor weather and in harsh environments and

feature user-friendly operation with a minimum number of controls.

1.1 Features

1.1.1 The Receiver (Rx)

• Can be used with or without the transmitter:

• Power Grid mode (without transmitter)

• Radio mode (without transmitter)

• Transmitter mode (with transmitter)

• Automatic depth determination when used with the

transmitter

• Semi-automatic depth estimation when used without

the transmitter

• Sensitivity level can be adjusted automatically or

manually

• Illuminated display for use in dark environments

1.1.2 The Transmitter (Tx)

• Transmits a 33 kHz signal which is coupled into the

line by:

• Induction, via the integrated antenna

• Direct connection, via the measurement cable and

alligator clip or via accessories such as the

transmitter clamp or adaptor cable

• Transmitter power; 0.1 W or 0.5 W - selectable

• Signal output; continuous or pulsed - selectable

a. Optional sonde - see “Spare parts and optional accessories” on page 28.

The Elcometer 701 is packed in a cardboard package. Please ensure that this packaging is

disposed of in an environmentally sensitive manner. Consult your local Environmental Authority for

further guidance.

To maximise the benefits of your new Elcometer 701 Pipe and Cable Locator please take

some time to read these Operating Instructions. Do not hesitate to contact Elcometer or your

Elcometer supplier if you have any questions.

2 SAFE USE OF THE INSTRUMENTS

• Direct connections to live cables

Direct connections to live cables should be made by qualified personnel only.

• Lines without a signal

The Elcometer 701 Receiver can only locate lines which emit a signal; lines which do not emit a

signal will not be located. If no lines have been found, it is important to always exercise extreme

caution when digging.

3 GETTING STARTED

3.1 Fitting batteries

3.1.1 Receiver (Rx)

The receiver is powered by 10 alkaline ‘AA’ batteries.

The status of the batteries in the receiver is checked upon start-up and indicated in

the display .

During operation, the receiver checks the battery strength at regular intervals. If battery capacity

falls below 10% of the threshold value, an audible warning signal is given and the current status of

the batteries is shown in the upper part of the display.

In order to replace the batteries, the battery compartment cover must be removed.

The instruments should be used with care. Follow the instructions given in these

Operating Instructions. Read and understand all warnings.

701_TMA_0429_00_03 A5.fm Page 3 Monday, November 15, 2010 10:22 AM

GETTING STARTED

To release the battery compartment cover, push the rubber

button away from the instrument handle and then lift away

the cover.

The batteries are contained in an enclosure which must be

removed from the instrument for access.

Place the batteries in the enclosure ensuring correct

polarity - refer to the diagrams on the enclosure.

3.1.2 Transmitter (Tx)

The transmitter is powered by 6 alkaline ‘D’ batteries

The batteries in the transmitter have to be replaced as soon as the red LED battery

indicator starts to blink (see page 6).

Should this occur while the user is busy locating a line with the receiver, there will be a change in

the signal at the receiver:

The batteries are located behind a cover on the base of the instrument. To release the cover, use

a coin or screwdriver to rotate the two screws a ¼ turn anticlockwise and then lift away the cover.

The batteries are contained in an enclosure which must be removed from the instrument for access.

Place new batteries in the enclosure ensuring correct polarity - refer to diagrams on the enclosure

(note that all the batteries are fitted in the same direction).

3.2 Battery care

Remove the batteries from the instruments if they are to remain unused for a long period of time.

This will prevent damage to the instruments in the event of malfunction of the batteries.

Alkaline batteries must be disposed of carefully to avoid environmental contamination. Please

consult your local Environmental Authority for information on disposal in your region.

Do not dispose of any batteries in fire.

3.3 The Receiver (Rx)

3.3.1 Parts of the instrument

1. Control panel with display

2. Speaker with volume control

The speaker gives various acoustic signals (e.g.

beeps with modulating pitch relative to the signal

strength).

When the receiver is switched on, the volume is set

at a standard level. The receiver will only start with

the volume at a different level if the volume has

been increased manually before switching off the

receiver.

3. Headphone socket (3.5 mm connector)

4. Battery compartment

5. Floor cap (protects the end of the instrument case).

3.3.2 Receiver control panel

1. Light sensors

Light sensitive photo cells to regulate the display

lighting automatically.

The display lighting can be activated manually for

one minute by briefly covering the light sensor.

2. On/Off switch

Press to switch on or off.

The receiver will also switch off automatically after

approximately 7 minutes of inactivity.

3. Display

Provides a visual indication of reception strength,

line depth, mode of operation, battery status and

menu items.

4. Control buttonsb

Button # 1 Button # 2 Button # 3

• Starts measuring depth

• Starts measuring depth • Selects the operating mode

• Increases receiver

sensitivity

b. The function of buttons 1, 2 and 3 depends upon the status of the system

GETTING STARTED

3.4 The Transmitter (Tx)

1. Accessory connector sockets

These sockets are used to create a

direct galvanic connection to the target

line or to create a connection using a

special connection set (e.g. transmitter

clamp or house connection set - see

“Spare parts and optional accessories”

on page 28).

2. Battery status indicator

When the battery status indicator is

red, the batteries need to be replaced.

3. On/Off button

Press and hold to switch on. Press

again to switch off.

All appropriate LEDs blink when the

transmitter is on, depending on operating function.

4. Control buttonsc

Button M Button P Button C

• Switches between

continuous and pulsed

signal output

• Switches between signal

power levels (0.1 W or

0.5 W)

• Switches between inductive

and direct signal coupling

c. The function of buttons M, P and C depends upon the status of the system

TRANSMITTER - USE, SETUP AND SIGNAL COUPLING

4 TRANSMITTER - USE, SETUP AND SIGNAL COUPLING

4.1 Using the transmitter

Follow the steps listed below in order to prepare the transmitter to search for lines in conjunction

with the receiver:

Your transmitter is now set up and transmitting signals. Now you can use the receiver to locate

metallic conductors - see “Receiver - use, adjusting sensitivity and setup” on page 16.

Step Action Page

1. Decide whether the transmitter signal is going to be coupled to the line by induction

or by direct connection. 10-15

• If coupling by induction, place the transmitter on the site to be searched. 14

• If coupling directly, connect the transmitter to the line to be located by the most

suitable method. 10-15

2. Switch on the transmitter. 6

3. Select the desired signal characteristics using the P and M buttons.

A green LED indicates that the respective setting is active. 9

4. Select the desired operating mode using the C button.

In direct mode, an LED next to the symbol indicates how good the

connection to the line is:

•Green blinking: good (low-resistance) connection

•Alternating red and green: sufficient connection

•Red blinking: poor/no (high-resistance) connection
