4. OPERATION

1) Remove the cover protecting the base plate surface (The Base Plate should be kept covered
when not in use.)
2) Referring to Figure 6, move the right sliding sight (A1) so that when looking through the
hole in the sight, the pendulum wire lines up with the left front sight (A). Read and record the
reading on the steel rule to the nearest millimeter.
3) Repeat Step 2 for the left sliding sight (B1), aligning it with the pendulum wire and the front
right sight (B). Read and record the steel rule reading to the nearest millimeter.
4) The calculation of the X and Y coordinates is done by software loaded as an app onto an
Android smart phone. The software can be downloaded off the Geokon website. Selecting
the App brings up the screenshot shown in Figure 4. Using the touch screen, enter the values
of A1 and A2 in millimeters and then touch the 'calculate' icon whereupon the X and Y
coordinates appear in the center of the screen.
