1.0 Introduction
CBS Products Ltd is a long established U.K company situated in rural Oakham, Rutland. From its
4-acre site, CBS design, manufacture, test and market a comprehensive range of quality products
for the electricity, telecommunication and CATV industries. Products include overhead line and
underground winches, cable drum trailers and stands, stringing equipment, in fact everything
required for the installation or erection of conductors and cables.
With a long history of designing standard and specialised equipment to meet the needs of
customers worldwide, CBS has invested in the latest computer aided design and analysis systems
and an integrated manufacturing plant.
The CBS Design Facility is available to discuss specific customer requirements for any product /
project, existing or new. Please contact CBS Products Ltd for further information.
CBS Products Ltd operate stringent quality controls throughout the organisation and has a quality
assurance system certificated to ISO 9001: 2008. Our total commitment to providing quality
products and service is reflected in the high standard of the finish, use and long life of all our
products.
There are certain controls and control functions, included in
the sonde, which are critical to the safe operation of the winch.
these safety critical controls are clearly marked in the
manual with the following symbol. It is imperative that these
operating and maintenance procedures are followed exactly, to
ensure safe operation.

2.0 Safety Instructions
The Duct Calibration Sonde is operated employing pneumatic compressed air upto 3
bar (45psi). Compressed air has a potential energy to expand and accelerate
materials, therefore care should be taken at all times during the operation to keep
the pressure as low as possible. The pressure should be reduced at the compressor
or by introducing a pressure regulator at the input to the duct.
The “Sonde” exits the duct at the opposite end to the compressor. This point is an area of high
risk the “Sonde” will be travelling at high speed. The following methods should taken to reduce
this risk.
Fit the “Sonde” catching mesh stocking on the exit end of the duct, the
stocking should have at least 200mm applied over the duct end.
Ensure, the duct end is not pointing were the exiting “Sonde” could
harm the public or operators.
Always ensure the escaping air is free to dispense without restriction.
Place barriers around the exit end together with caution signs.
Only fully trained and competent staff should be allowed to operate
this equipment.
There are certain controls and control functions that are critical to the
safe operation of this equipment, these safety critical controls are
clearly marked in this manual with the following symbol.
It is imperative that these operating and maintenance procedures are followed exactly to ensure
safe operation.

3.0 General Description
The Duct Calibration “Sonde” and Detector have been designed to ensure that ducts being
employed for cable blowing have unrestricted bores, or locates the point(s) where ducts are
damaged or restricted.
This operation should be conducted prior to the cable blowing operation and the ducts left capped
and sealed.
The “Sonde” device is suitable for a range of direct buried plastic ducts from 29 mm bore to 57
mm bore. The front end of the “Sonde” has a range of 7 sizes of calibration noses as standard,
38 mm, 35 mm, 33 mm, 30mm, 28mm 26mm and 24 mm, (other sizes are available on request).
The electronic module fits into the body of the “Sonde” for potential detection
later. The “Sonde” is inserted into the duct, calibration nose cone first and the
compressor made ready. The catcher stocking is fitted to exit end of duct and
operators warned of commencement of the operation.
The operation of the compressor at 3 bar (45psi) can commence, during which time the “Sonde”
will travel down the selected duct very rapidly, several seconds in most cases. The “Sonde” will
exit the duct and be caught by the stocking.
In the event of non-arrival of the “Sonde” at the exit end, switch off the compressor and
commence location of the “Sonde” along the route by use of the detector. Locate the “Sonde”
and dig and repair the damaged duct. Ensure the sonde unit is salvaged.

5.0 Operation Instruction
See diagram Figure 1 for typical layout of a duct requiring calibration prior to cable blowing. To
calibrate the duct the following procedure should be employed.
Fit the catcher stocking to the Exit End of the duct. Ensure that stocking is
applied at least 200mm over the end of the duct.
Assemble the “Sonde” with the correct size calibration nose cone and commence operation of the
electronic sonde by inserting the battery provided, and enter into the plastic body. (The Sonde will
now emit a 33 kHz frequency. (see section 5.0 for further details).

Always check the operation of the sonde and detector before inserting the sonde into
the duct. DO NOT PROCEED IF SIGNAL IS NOT DETECTED.
Rectify the fault and proceed. Always check the condition of the duct seals, replace if
necessary.
Set the compressor to 3 bar (45 psi) or pressure regulator in the duct line to 3 bar.
Insert the Sonde into the duct (eg. 40/32 mm) with the calibrating nose cone end
away from the compressor.
Secure the duct to the compressor with connecting hoses.
Open the air supply line, this will propel the Sonde along the duct route.
This operation only takes several seconds.
Inspect visually to see if the Sonde has exited from the duct in the catcher stocking.
Close the compressor airline.
If the Sonde has travelled the duct route the system is calibrated.
If the Sonde has not exited from the duct route, again switch off the air compressor.
Keep well clear of the exit end of the duct as it is compressible and may release the
Sonde unexpectedly at anytime.
Make sure the airline is removed from the duct and the air fully exhausted.
Employing the detector (following the manufacturers operating instructions).
Walk the duct route operating the locator perpendicular to the duct. The detector will indicate
audibly when the Sonde is found.
Dig down to locate the damaged duct and repair. Ensure the sonde is salvaged. Re-check the
duct route again with sonde until the sonde exists at the duct exit end.
When the duct has been successfully calibrated, cap and seal both ends to ensure integrity.

6.0 Assembly and Maintenance
6.1 Sonde Assembly
Check the battery condition of the electric module. Replace if necessary (see figure 5.1.1) ensure
that “O” ring seal is fitted correctly (see fig 5.1.2). It is recommended that a spare battery is
always available.
Electric Module Fit Battery This Way “O” Ring Seated Correctly
Components Fig 5.1.1 Fig 5.1.2
Insert the shock absorber into the sonde body and press fully down to the front end.
Assemble the sonde adaptor to the electric module, ensure both parts are screwed tight. Screw
this unit into the sonde body and ensure it is tightened correctly.
Assemble both seals, ensure they are in good condition, replace if worn or split. Ensure that lip of
the seal faces towards the rear of the unit, i.e. towards the tail endpiece.
Assemble the tail endpiece to the sonde adaptor and ensure it is tightened correctly.
