prompted by means of continuous alarm. At this time, press the↓ key
to change the direction into↓. Then detect the horizontal rebar of grid
pattern. Similarly, detected point should select the position among
crossing points of grid pattern longitudinal rebar to avoid the influence
on detected horizontal rebar by grid pattern longitudinal rebar. The
trolley held by hand is moved from up to down (pay attention to the
direction of trolley). One black block shown on the screen is also
moved from up to down. After hearing the alarm, detected rebar is
showed on the screen in the formation of being parallel 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
downwards, when D (distance that the trolley moves) is not less than
500/1000/2000, it is prompted by means of continuous alarm. At this
time, press the SAVE key to save detection results into current set
project No.
