Measuring Depth Near End Or Bend Of Pipeline; Confirmation Of Burial Depth Of Pipeline - FujiFilm PL-G.MAX Operation Manual

6-4 Measuring a depth near the end of a pipeline and near a bend.
At the end of the pipeline or near a bend, the magnetic field surrounding the pipe is disturbed. Therefore, the risk of error
when measuring its depth increases. Using the Transverse depth measurement mode makes it less susceptible to magnetic field
disturbances. Use this mode for such situations after confirming there is an end or bend in the pipeline.
6-5 Confirmation of buried depth condition of pipeline
When using the conventional depth mode, there is a chance of misinterpreting the depth/shape of a pipeline when there are sudden
changes in pipeline depth, as shown in the first diagram below. When using the continuous depth mode, the pipeline depth is
measured in certain intervals with the measurement depth displayed, as shown in the second diagram below. This mode makes it
easier to accurately confirm the depth situation of the pipeline. This mode is also useful when trying to find obstacles to avoid (such as
bends in pipes etc.) when installing new pipelines.
