Introduction

The C.Scope Function Checker is a simple-to-use product

that allows the performance of C.Scope Cable Avoidance

Tools, Locators, Signal Generators and Transmitters to

be checked.

The robust and portable Function Checker is battery

operated, and designed for use in a variety of locations

such as at a depot or out on site. It can test a wide

range of C.Scope equipment, to confirm that they are

operating correctly.

The Function Checker will not identify if a C.Scope

product has suffered any form of mechanical damage

that has compromised its structural integrity or ability

to withstand water or dust ingress UNLESS that damage

has also affected electronic performance. The ‘Condition

Checks’ also detailed in this Manual are an essential part

of the checking process to identify such damage and

MUST be carried out on every unit.

It is important to note that the Function Checker does

not recalibrate, service, repair or alter in any way, the

operation of any C.Scope product.

Correct use of the Function Checker allows the operator

to confirm that the product is detecting the signals it is

designed to detect (in the case of C.Scope Locators) or

transmitting the signals it is designed to transmit (in the

case of C.Scope Signal Generators and Transmitters).

The following C.Scope products are covered in this manual:

 C.Scope CXL Locator

 C.Scope DXL Locator

 C.Scope MXL Locator

 C.Scope Cable Avoidance Tool

 C.Scope Cable Avoidance Tool XD

 C.Scope grey SGA Signal Generator

 C.Scope black SGA Signal Generator

 C.Scope grey 1Watt SGV Signal Generator

 C.Scope black SGV Signal Generator

 C.Scope MXT Transmitter

 C.Scope Signal Generator (pre 2003)

WARNING If a C.Scope product fails any of the Condition Checks or Performance Checks then it should be withdrawn

from service immediately and returned to a C.Scope Authorised Service Centre.

Using this Manual

The Function Checker allows Performance Checks to be carried out

on a wide range of C.Scope Cable Avoidance Tools, Locators, Signal

Generators and Transmitters with each model covered in a specific

section of this manual. It is essential to identify exactly which C.Scope

product you wish to test before attempting any of the Checks.

All C.Scope products should undergo two distinct types of checking:

‘Condition Checks’ and ‘Performance Checks’. This manual has

sections devoted to both of these procedures and it is important that

both are carried out for every product.

The ‘Condition Checks’ should always be completed before the

‘Performance Checks’.

Condition Checks for all C.Scope Locators are covered in the section

‘Condition Checks C.Scope Locators’ on pages 9-10. Condition Checks

for all C.Scope Signal Generators or Transmitters are covered in the

section ‘Condition Checks C.Scope Signal Generators and

Transmitters’ on pages 11-12.

Selecting a suitable location

In order for the Function Checker to correctly Performance Check a C.Scope product it is important that

there are no strong background electromagnetic signals present that may cause interference. Therefore,

the intended location for using the Function Checker should be checked for background electromagnetic

signals before use.

This can be achieved by scanning the area using the Power and Radio Modes of a Locator. If the Locator

indicates no large power or radio signals then the area should be suitable for Function Checker testing.

(Generally, ‘large’ signals are those that are detectable with the Locator sensitivity control set at 50% or

less on either mode).

NOTE

Electromagnetic signals can be caused or influenced by any of the following:

 The operation of other Signal Generators/Transmitters and Sondes in the same area as the Function Checker.

 Nearby electrical plant such as transformers or main switch boards.

 Live overhead or underground electricity cables directly above or below the Function Checker.

 Large metal objects such as steel workbenches or filing cabinets.

 Vehicles or plant in close proximity to the Function Checker.

 Metal-based flooring, including steel reinforced concrete.

Condition Checks C.Scope Locators

The following C.Scope Locators are covered

in this section:

 C.Scope CXL Locator

 C.Scope DXL Locator

 C.Scope MXL Locator

 C.Scope Cable Avoidance Tool

 C.Scope Cable Avoidance Tool XD

The following Condition Checks MUST be carried out prior

to Performance Checking any C.Scope Locator with the

Function Checker. These Condition Checks are designed

to identify if there is any mechanical deterioration to the

Locator under test that may compromise performance or

make the product vulnerable to water or dust ingress.

If the Locator does not pass all of the Condition Checks

then it should be withdrawn from service immediately

and returned to a C.Scope Authorised Service Centre.

Performance checking Cable Avoidance Tool / XD

NOTE In order to carry out Performance Checks using the Function Checker, it is necessary to be familiar

with the correct operation of the C.Scope Locator to be tested.

NOTE Only use the Function Checker in an area that has been scanned and found to be suitable for use,

as described in the ‘Selecting a suitable location’ section on page 8.

These tests should NOT be carried out in the close vicinity of any active Signal Generators, Transmitters or Sondes.

1. Place the Function Checker on the ground with the Accessory Tray securely clipped to

the underside of the Function Checker.

2. Switch ON the Function Checker. Check the Battery Condition Indicator in the bottom

left hand corner of the Function Checker display. If there is only one segment or no segments

of the indicator filled in then the batteries must be replaced before the Function Checker

can be used.

3. Position the Locator alongside the Function Checker with the base of the Locator touching

the ground and one of the Function Checker Accessory Tray Retaining Clips.

NOTE The Locator can be placed either side of the Function Checker but must be touching the side and held vertically.

If the Locator is transferred from one side of the Function Checker to the other the same visual response should occur

on the Locator. This can be a good indication that there are no interfering signals from nearby sources. If the Locator

responses are not the same then try testing in a different location.

8. Check the correct operation of the Sensitivity Control by adjusting

it first fully clockwise (maximum sensitivity) and then fully

anti-clockwise (minimum sensitivity).

CORRECT RESULT: The Locator bar graph should change

from showing a full-scale response when on maximum

sensitivity to no response at all when on minimum

sensitivity.

NOTE If the bar graph does not drop to zero when on minimum sensitivity it may be due to background electromagnetic

signals. Refer to the ‘Selecting a suitable location’ section on page 8.

9. Rotate the Sensitivity Control so that the bar graph

shows a mid-scale response with the audio tone sounding.

Slide the Locator along the side of the Function Checker

to find the position of maximum signal, re-adjusting the

sensitivity, if necessary, to keep the indication at mid-scale.

CORRECT RESULT: The Sensitivity Control should now

be at a rotation of approximately a one-quarter turn

from minimum.

NOTE It is important to NOT adjust the sensitivity setting of the Locator or to move it from this position for the

remaining tests.

Carry out a ‘SONDE’ depth measurement by pressing the depth button

twice and holding on the second press.

CORRECT RESULT: The word ‘SONDE’ will flash on the display

and a depth of between 0.85m and 1.20m will be indicated.

NOTE It is essential that the depth button is pressed twice in quick succession to select ‘SONDE’ depth measurement

(indicated by the word ‘SONDE’ appearing on the screen) and not a ‘Line’ depth measurement as this will give an

incorrect reading.

NOTE The XD displays depths to the nearest 0.15m in Sonde Mode and so the indicated depth may vary by 0.15m

depending on how close it is to indicating the next depth level.

If all of the ‘Condition Checks’ (pages 9-10) and ‘Performance Checks’ (pages 14-19) have been completed successfully

then the Locator is operating correctly in all three modes.
