This menu is identical to the Output Menu in Digital 2D Mode. See the relevant section
above for the digital antenna you are using.

Step 2: Begin Collection
Once the antenna is centered over the starting coordinate press the green Start button. This initiates data
collection of Line 1. Nothing will happen until you begin to push or pull the cart or survey wheel. Once
the cart or survey wheel starts moving in a forward direction (or whichever direction was used during SW
calibration) you will start collecting data and see the yellow line progress across the screen.
After traveling the distance that you specified in 3D Setup, the SIR 4000 will automatically stop
collecting data. The file will save and the system will automatically increment to the next line.
Orientation – Positioning the Next Line
Forward or Reverse Line Orders:
Move your cart back to the baseline that you started from.
Zigzag Line Order:
Turn your antenna around and position the center over the next line, but going in the
opposite direction.
Start/Stop Buttons
The Start and Stop buttons offer different functions depending upon how long you press them.
Green Start Button:
Long and Short presses both start collection of a single line or continuation of a
paused line when using Add Segment.
Red Stop Button:
Short press ends data collection along a line. Long press saves the grid and exits data
collection.
