Markers
. Pressing the physical A/C button on the left-hand side of the case, while
the instrument is collecting data, adds a series of sequentially numbered vertical lines to the Bx
and Bz traces. For example, if the inspector was inspecting a circumferential weld marked up in
clock positions running from 1 to 12 o’clock, 12 being top dead center, the data could be marked
up accordingly. When the probe passes over one of the clock marks, the operator would press
the A/C key to mark the region of data corresponding to the marked position. The exact sequence
of numbers is configured in the
Marker Setup
dialogue box, found in
Home/Markers
.

The default settings assume you are starting at 1 o’clock and ending at 12 o’clock. However this
may not be the case. For example, you may be starting at 9 o’clock, scanning through 12 o’clock
and ending at 2 o’clock. In this case you would want the markers to run in the following sequence:
9, 10, 11, 12, 1, 2. For this configuration you would require the following settings:
1.
The numbers are increasing clockwise. This should not be confused with a probe moving
in the clockwise direction.
2.
The maximum number in the sequence is 12.
3.
The sequence starts with 9.
4. The sequence ends with 2.
5.
If the operator then wanted to reverse direction and scan from 2 o’clock, through 12 and
end at 9 o’clock, they would simply press the “Swap” button to reconfigure the markers.
6.
If the operator was inspecting a linear weld, rather than a circumferential weld, then the
numbered sequence would not repeat in a rotational manner. In this case the markers
would be configured to either increase 9, 10, 11, 12, 13, 14… Or decrease: 9, 8, 7, 6, 5…
