Figure 6-14: Concrete Cal menu
A red crosshair will appear on the screen, along with a dialog box showing the position and
depth to the center of the crosshair. Once you have determined the Concrete Cal (see below),
you can touch the screen and drag the crosshair to accurately determine the depth and position
of any object.
The Concrete Cal can either be manually set by pressing Concrete Cal -/+ or set automatically
by pressing Auto Cal.
Pressing Auto Cal will analyze the hyperbolas on the screen and determine the proper
Concrete Cal value. If you are satisfied with this value, press Apply and it will re-display with a
new depth scale (Figure 6-14). If you don't want to change the value, press Cancel instead.
Note: in most cases, the Concrete Cal value should typically be between 85 – 130.
You could manually set the Concrete Cal if you've verified the depth of the concrete or an
object, by moving the crosshair to the top of that object response and adjusting the Concrete
Cal until the depth indicator matches what you've measured (also known as " ground-truthing").
Press Apply to accept this value and it will re-display with a new depth scale (Figure 6-15).
