Arrow indicators will appear to guide to the center of an object. Once
the object center is detected, a center line icon will appear. The
alignment lines (Fig. 2, E) on top of the hand-held radar scanner can
then be used to guide marking the wall.
Confidence Meter
The confidence meter (P) gives a relative indication of signal strength.
A fully lit confidence meter indicates a strong data signal and high
confidence of the material identified below the surface.
A partially lit confidence meter indicates a weaker signal and less
confidence of the material identified below the wall.
To improve the signal strength, follow these tips:
– Scan in a straight line, either horizontal or vertical.
– Scan uniformly without lifting from the surface of the wall.
– Always scan SLOWLY to achieve maximum sensitivity.
– Do not touch the surface being scanned with your other hand or
– Review Detection through Special Surface Conditions
Material Identification Window
The material identification window (Q) will give further detail of the item
identified below the wall surface. Multiple items could be displayed if
they are all directly below the hand-held radar scanner's position.
Items identified include:
Plastic / PVC
NOTE: When the hand-held radar scanner is directly over a live wire,
the live electric graphic will appear in the main scanning window (O)
and the live electric icon will blink in the material identification window
(Q).
When the hand-held radar scanner is near, but not directly over a live
wire, the live electric icon will blink in the material identification window
(Q). This indicates that there is live electric in the vicinity of the hand-
held radar scanner.
