Select mode of operation i.e line tracing, sonde tracing, power line tracing & corresponding frequency of operation per person option.
Line tracing mode – the operator merely has to are available parallel line with the inserted traceable rodder or buried armored OFC being traced. The LF will provided three ways of guiding the operator – the road on the display screen become strong as proven because the operator aligns, a red LED gentle up on the screen & the handle of the LF goes into a relentless vibration mode.
In case of sonde locating mode for detecting blockages in buried pipe, step one is to detect & confirm proximity to sonde inserted inside buried duct. The signal will carry on rising larger and will first reduce (on account of AGC) and then stabilize to within +/-5 digits to localize presence of the sonde and point out that the operator is standing over or very near the Sonde inside the buried duct. (Refer step three visual).
Step 4 Because the buried duct may be buried at an angle to the horizontal, the operator first needs to kind a circle of approx. 5 to 10 toes radius around the purpose at which sonde was localized. By strolling across the circle, the direction finding mode allows the operator to know the exact orientation of the sonde and due to this fact the buried duct. (Refer step four visual).
The operator then walks alongside the route of the sonde recognized from one edge of the circle established. The operation first sees a null i.e two white and black circles indicating that he is about to be over the sonde. Strolling a few steps further will present a sonde picture as shown indicating that he has established actual location of the sonde. Walking another couple of steps additional provides the nulls again confirming that the operator has passed the sonde.
