Figure A-21 Graphical display during Search mode.
If you stop the survey, you can press the “NEXT” key to pop-up the graphical
display of the precession decay signal of the last reading. Very sharp, rapid
decays indicate possible poor signal conditions. Please see Figure A-18 on
page A3-18 for an example of the signal quality display.
Note: The values that you see for the line and station in the numeric display are
the last ones entered in a previous mode. The search mode does not use
these for any purpose, so please ignore them.
