Using “Set Dielectric”
The Set Dielectric function requires that the data contains at least one hyperbola. This hyperbola should
come from a target that you have scanned across at a 90 degree angle.
1
Collect a section of data and back the Mini XT to your chosen hyperbola.
2
Use your finger to position the horizontal crosshair at the top edge of positive wavelet (for metal
objects).
3
Select Calibrate from the menu carousel and then select Set Dielectric.
4
Select Step and click the middle keypad button to change fine/coarse adjustment and the click
Up/Down to chance the dielectric value.
5
Match the shape of the blue hyperbola template to the actual hyperbola in the data.
6
Click Accept when done.
Using “Auto Depth”
The Auto Depth option is designed to calibrate for depth by automatically calculating the concrete
dielectric. Auto Depth is designed to return a dielectric value that is within 0.5 of the actual dielectric
value. Like Set Dielectric, Auto Depth requires that you have hyperbolas in the data. Those hyperbolas
should also be at least 2” (5 cm) deep in order for the algorithm to return accurate values.
1
Collect a section of data containing hyperbolas which are at least 2” (5 cm) deep.
2
Select Calibrate from the menu carousel and then select Auto Depth. The Mini XT will automatically
calculate the dielectric value and adjust the vertical scale using the new dielectric to recalculate the
depth of targets.
