Original image
Restores the image processed result to the original state and displays
unprocessed raw data.
Distance feed
scan
Scan method that performs scanning in accordance with Handy Search's
traveling distance, using the distance detector mounted on the wheels of
this product.
Time feed scan
Scan method that performs B-mode scanning at preset time intervals,
regardless of movement of this product.
Relative dielectric
constant
Object-specific coefficient. The radio wave propagation velocity changes
with the relative permittivity (dielectric constant). Therefore, the wave
propagation velocity and search depth change based on the relative
permittivity of the concrete. Calculation error of search depth can be
reduced by setting a depth calibration value.
