Repair & Calibration - Function Check - Training

Repair & Calibration

Altech Distributors is the approved C.Scope service centre in Australia for the maintenance, repair and calibration of C.Scope Pipe and Cable Locators, Receivers, Signal Generators, Transmitters and Accessories.


The accuracy of electronic components used in all instruments naturally drifts over time. Therefore, it is necessary to calibrate instruments at regular intervals as defined by the manufacturer. Calibration improves the measurement performance of an instrument. Benefits of maintaining properly calibrated equipment include reduced measurement errors and consistency between measurements. To help you meet your calibration needs, Altech Distributors provides calibration support and services that include manual calibration procedures, and use of a factory built and calibrated function checkers, designed specifically for their products.


Altech Distributors strives to achieve the highest level of quality in every product it sells. Before a product leaves our factory, it undergoes testing and inspection.

The following products DO NOT require annual calibration:

  • C.Scope CXL Cable Avoidance Tool (part number ZCSCXLCAT-33G)
  • C.Scope DXL Cable Avoidance Tool (part number ZCSDXLCAT-33G)
  • C.Scope MXL Locators (part numbers ZCSMXL-33-8-640 and ZCSMXL-33-8-512) 
  • C.Scope SGA Grey Signal Generator (part number ZCSSGA-33G)
  • C.Scope One Watt SGV Signal Generator (part number ZCSSGV1-33G) 
  • C.Scope MXT Transmitters (part numbers ZCSMXT-33-8-640 and ZCSMXT-33-8-512).

We continue to recommend that the following C.Scope products DO require calibration 
every 12 months:

  • C.Scope Cable Avoidance Tool (part number ZCSCAT-33), 
  • C.Scope Cable Avoidance Tool XD with depth measuring (part number ZCSCATXD-33) 
  • C.Scope SGA Signal Generator (part number ZCSSGA-33)
  • C.Scope SGV Signal Generator (part number ZCSSGV-33)
  • C.Scope Function Checker (part number YIRFC).

Put simply, all C.Scope Locators and Signal Generators with a grey case DO NOT require annual recalibration and all C.Scope Locators and Signal Generators with a black case DO require annual recalibration.



C-Scope Locator Function Checks

It is recommended that the operation of the C.Scope Cable Avoidance Tool and Signal Generator is checked before use.


These checks DO NOT guarantee full system performance. The Cable Avoidance Tool and Signal Generator should be returned to the manufacturer or an approved agent for recalibration every 12 months.


Battery Condition

Check by depressing the On/Off switch beneath the handle. The display will show at least one solid segment if the batteries are ok. Ensure power on tone is heard.


Power Mode

Select Power Mode. Set Sensitivity fully clockwise and point the body of the C.Scope Cable Avoidance Tool at a fluorescent light from a distance of 1m. Switch the light on. A loud tone should be heard and the display should read greater than 50% full scale. Reducing the sensitivity should cause the displayed reading to reduce and the tone to cut out.


Radio Mode

Select Radio Mode. Set the Sensitivity fully clockwise and, from a distance of less than 0.25m, point the unit at a metal conductor of length greater than 100m (for example a pipe or cable). A warbling tone should be heard. The display should read greater than 50% full scale.


Generator Mode

Locate an outdoor test area that is free from extraneous fields resulting from overhead and underground cables. The area should also not be near fences, steel framed buildings, or on reinforced concrete as the signal will be reduced.

Place the Signal Generator on the ground in the normal orientation and switch on - a tone should be heard. Set to Continuous and ensure highest output power is selected.


With the C.Scope Cable Avoidance Tool in the orientation shown, and Sensitivity rotated.

Depth Measurement Checks

An area free of services, metal structures, etc should be chosen (beware of reinforced car parks). A search with the C.Scope Cable Avoidance Tool in all 3 modes will help confirm the absence of other services. An insulated cable or wire 20m+ (not supplied) is laid out on the ground surface and the far end connected to a ground stake and earthed. The near end is connected to the red Connected Mode lead.


The black ground Lead should be laid at right angles to the 20m wire and earthed at the far end with a ground stake. The plug should be inserted in the connector on the Signal Generator.

The Signal Generator is turned on with lowest power, and continuous mode selected. The C.Scope Cable Avoidance Tool should then be held vertically above the longer wire, approximately midway along it, ie. 10m from the Signal Generator.


The depth can then be measured. It is best to make a few readings at different depths. (Beware - metal step ladders affect the accuracy!)

Signel Generator Function Checks

Battery Condition

Select Continuous. Good batteries will be shown by a loud clear audio tone. Bad batteries give an interrupted audio tone. On the SG-V the display will show at least one solid segment if the batteries are ok.

Induced Mode

This can only be checked in conjunction with a C.Scope Avoidance Tool as described in Locators Function Check.

If the unit does not meet the results required, repeat the test with another C.Scope Cable Avoidance Tool to determine whether the Signal Generator is suspect.

Connected Mode

Set the minimum output level, insert the connection lead and the long earth lead and then connect the red lead to the long earth lead to create a short circuit. The pitch should change to a low tone.


The leads should be arranged to create an open loop on the ground of approximately 1m diameter. Check that a signal can be detected by the Cable Avoidance Tool (in Generator Mode) when pointed closely at the loop.

Altech offers a range of training for your operators and training personnel and is available on your site, or at our Office. Training is carried out by a qualified instructor and each trainee receives a certificate to confirm they have received the training.



To ensure candidates understand the need to use location equipment and to instruct them to operate pipe and cable locators in an accurate and safe manner.



Typically the full course duration is 4 hours. Refresher course being 2.5 Hours

Candidate Numbers

Up to 10 candidates can be trained in a single course.


  • Our Training Facility:
    • We can provide training at our office in Lilydale Victoria.
  • Customers Address:
    • No special facilities are needed apart from a suitable room to allow the theory to be presented without disturbance. Access to an area where there are buried services is also required. (Street with buried telecommunication cables,  power cables, water and/or gas services.




Upon completion of the course each trainee will be provided  with a  certificate to confirm they have completed the course.



The course consists of theoretical and practical training involving hands on use of the actual locators to detect and trace the route of buried services. The actual agenda is summarised below:


This will cover the different types of buried services that exist, current legislation concerning detecting buried services, the safety implications of not using a locator plus ancillary locating work to be done (use of “Dial Before You Dig” cable plans, and observation of street fixtures etc.)
THEORY: A general overview of how locators work followed by a step by step explanation of exactly what can and cannot be detected on the different modes. Typically use of the Cable Avoidance Tool alone is covered first followed by use of a Signal Generator. Accessories that are appropriate to the work that the candidates carry out will be included. Correct maintenance and care of the equipment is also discussed.



Candidates are shown the correct way to handle and operate the equipment on all modes before being given the opportunity to gain hands-on experience themselves. Any bad habits will be quickly picked up and corrected. Time is spent practising the techniques of detecting signals, pinpointing their source and then finally tracing the route of the service. A Signal Generator and the relevant accessories will also be used.


Special Requirements

Our training is derived from experience in using locators in a diverse range of situations over many years and we bring this experience to the training course. We always seek to make our courses specific to the type of work that the candidates are involved with and encourage candidates to participation in discussion on the subject of locating throughout the course. The training is carried out in a friendly, relaxed manner and the theoretical content is covered in simple, easy to understand terms.
