to adopt the general measurement mode.
2) When rebar space of object is small, such as beams, it is
better to adopt the dense rebar measurement mode.
ZBL-R800 designs a specific measurement method to dense
rebar objects.
In beams or pillars, there are often densely packed rebar, sometimes,
the pure rebar space is about 1.5 times rebar diameter. Under this rebar
distribution, there is little change of thickness value of cover, and
generally rebar detector is difficult to indentify number and location of
rebar.
At this point, it is recommended to use the method of
dense rebar measurement.
In the general-scan interface, pressing 【a】 key for a shift between
general measurement and dense rebar measurement. When in dense
rebar measurement, “
” symbol will occur in status bar. Under dense
rebar measurement, rebar location, measurement of thickness of cover,
stored method is the same with general measurement.
When using dense rebar measurement, users should pay
attention to following points:
1) The scanning speed should not be too fast, it is better to
be less than 15mm/s.
2) During scanning, to maintain one-way movement of
sensor and ensure the parallel between sensor and
tested rebar.
3) To try to select the larger position of cross bars for
measurement.
4) After completion of first scanning, it is recommended for
an inspection in reverse order to improve its reliability.
Attention: when pure rebar space is less than 1.5 times
rebar diameter and thickness of cover is greater than 2 times the
space, the last rebar can not be interpreted automatically. Under
