default will be set as known diameter. Project No. of this detection is
set.
3. The probe is placed in air and away from the metal (at least 0.5m
away from the metal) and strong electromagnetic field interference.
Press the ENTER key to reset and eliminate the environmental
influence.
4. According to design data or experience, the rebar direction is
determined. If rebar direction is not determined, horizontal &
longitudinal direction and position of grid pattern rebar are detected
according to detection method of rebar.
5. The trolley and probe are placed on the surface of detected body
and the probe is moved at uniform speed in parallel with detected
rebar. The speed should be less than 20mm/s. According to → shown
on the right upper corner, firstly, longitudinal rebar of grid pattern is
detected. Detected point should select the position among crossing
points of grid pattern horizontal rebar to avoid the influence on
detected longitudinal rebar by grid pattern horizontal rebar. The trolley
held by hand is moved horizontally from the left to the right (the
speed is not more than 20mm/s). One black block shown on the screen
is moved horizontally from the left to the right. After hearing the
alarm, it indicates there is rebar under the probe and rebar is showed
on the screen in the formation of being vertical to X-axis. At the same
time, covering layer thickness of current detected rebar is showed
under the T. During continuing to move the trolley to the right, when
D (distance that the trolley moves) is not less than 500/1000/2000, it is
