sensor is where the rebar is in (figure3-11(C)).
2) Rotating the sensor and making the signal in maximum state. At
that time, the direction of sensor is the direction of tested
rebar.(figure3-11(D))
4. Measurement of rebar diameter
1) Resetting sensor in accordance with the method 2.
2) Identifying rebar’s location and direction precisely.
3) Placing the sensor above the tested rebar and paralleled with it.
Pressing 【a】 key, after about 2 seconds, the tested result of
diameter will be directly shown in the position of “Dia”. The
instrument will measure the thickness of cover simultaneously
shown in “Cover” in figure 3-12. Under the mode of automatic
storage, it will store diameter value and thickness of cover
automatically and the storage amount increase by 1. Under the
mode of manual storage, if pressing 【SAVE】, it will store
diameter and thickness of cover and the storage amount
increase by 1.

3.4.2 Grid-scan
Grid-scan mainly displays the distribution of grid-distributed rebar
through grid diagram, and display the location of rebar and the
thickness of cover at the same time.
