OPERATION IN EACH SITE SITUATION
6-10 When there is a power station nearby
Begin by selecting Direct mode (DIR).
When there is a nearby substation, the pipeline(s) may not be
detectable due to the interference of high-voltage lines, or the
Substation facility.
In such a case, find a place before and
after the interference of high voltage lines and
substation equipment, as shown in the diagram to the left.
Detect the pipelines from both areas.
You may then assume the pipeline's shape and direction
in between the two points.
6-11 When detecting near buildings
When a pipeline is buried near buildings, the position and
depth may become unclear due to the interference of steel
structures etc.
In such a case, use the direct mode (DIR), with an external
magnetic coil. Additionally, perform the detection
next to the break of the building or guardrail.
