concrete and paralleling with tested rebar, then moving sensor along
a direction in a uniform speed, when sensor going towards rebar,
scrollbar will be lengthen and the signal value will become larger
and larger , current thickness value is decreasing(figure 3-11(A));
when the sensor going over rebar , the thickness value of cover will
be locked automatically( figure 3-11(B)). If the method of storage is
set in “automatic storage”, instrument will store the thickness of
cover automatically and the storage amount will increase by 1
automatically at the same time. If it is set in “manual storage”,
after instrument locking the thickness of cover, pressing the
【SAVE】key, the value will be stored and the amount will increase
by one. When the sensor goes over rebar, the buzzer will alarm.

If you want to identify the rebar’s location and direction precisely,
please operate as follows:
1) Moving sensor in a reverse direction and identifying the
location of minimum current thickness value, then equaling the
current value with thickness of cover, therefore, the position of
