This equipment should be used only by per-sonnel who have been given the appropriate training and who are competent to use it. These instructions are to be made available to operators of this equipment at all times. Failure to observe these safety instructions could result in serious personal injury and/or property damage.

1.0 Safety Instructions The Duct Calibration Sonde is operated employing pneumatic compressed

air up to 45psi (3 bar). 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 8” (200mm) applied over the duct end. See figure 2.

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.


The Sonde device has been designed to test the integrity of the duct and locate the point(s) where duct is blocked, 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 PE and PVC ducts nominal sizes from 1” to 2” with various SDR see Table 1. The Sonde device consists of three components (sold separately):

SONDE P/N 88283;

ADAPTER SONDE M10X1.5 THREAD P/N 89394;

MISSILE P/N 89396, 88285, 88286, 88287 for different sizes of the ducts;

The Sonde P/N 88283 and Adapter P/N 89394 fits into the Missile, which is in-serted into the duct, calibration nose cone first and the compressor made ready. The catcher stocking is fitted to exit end of the duct and operators warned of commencement of the operation, see Figure 1 and Figure 2. The compressor operating pressure is 45 PSI (3 Bar) makes the Missile travel very rapidly, several seconds in most cases. The Missile will exit the duct and be caught by the stocking. In the event of non-arrival of the Missile at the exit end, switch off the compres-sor and commence location of the Sonde, using the DETECTOR P/N 88280. Locate the Sonde and dig and repair the damaged duct.

Activate the electronic sonde by inserting the battery provided. Screw the sonde into the tail end piece of the missile and assemble into the plastic body ensuring both parts are screwed tight. (The Sonde will now emit a 33 kHz signal.)

Always check the operation of the sonde with the detector before inserting it 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 or pressure regulator in the duct line to 45 psi (3 bar). Insert the Sonde into the duct with the calibrating nose facing the direction of travel, 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, 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 detec-tor 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 en-sure integrity.
