Determination of the pipe position
When a pipeline is energized a magnetic field of force is created
ring-shaped around the pipe. To locate this field of force proceed as
follows:
• Connect search coil type FS 3A to the DUOPHON®
receiver (Item 15)
• Connect earphones (Item 9)
• Turn rotary switch (Item 13) into position 13.4 or
• Turn rotary switch (Item 13) into position 13.3 and push
microphone key (Item 8) (when power carrying cables
and cathodically protected pipes are concerned)
• Move search coil along the pipe's trace.
Don't let the search coil swing around the handle -
wrong values would be indicated !
MINIMUM METHOD
When the minimum method shall be applied the search coil will be
clicked into 0 degree position (Refer to pict.5)
The magnetic field of force produces the signal course as pictured
above. This can be controlled via the meter (Item 16) and the
earphones (Item 9).
