Here's what an "out-and-back" Run
looks like before using the "Test
Track" Routine:
It's 100 ft long, and it is symmetric
about the Turnaround Point at 50 ft.
After using EDIT/TEST TRACK,
here's what it looks like when you
graph both parts of the line:
Now we have two separate 50-ft lines,
and the profiles lie on top of each
other. The only place the profiles
show some minor deviation is where
the operator walked off line for a short
distance but eventually got back on
line.
This shows that the “Out” portion of the Run matches the “Back” portion of the Run almost
exactly. You should now compare this data to data that you collected in the past on this same
“Test Track”. If today’s data matches the data collected several years ago, this means that three
things have happened:
1. The floor where your Test Track is located has not changed because of an earthquake,
expansive soils, or thermal effects.
2. You measured along the same line. If you measure only as little as ¼ or ½ inch off line,
the profile will be different because the elevations on the floor will be different at
different locations.
3. The Dipstick is still working exactly the same as it was two years ago when you last
measured the Test Track.
