Page 29 ZBL-R630A Rebar Detector Figure 3-36 Measuring line Buzzer sounds. At that time, the instrument prompts sensor goes over rebar, then moving sensor in the opposite direction to find the location of minimum value of current thickness—exact location of rebar. Signal value changes from small to big and then to small. When sensor gradually approaches rebar, signal value gradually becomes larger, or signal value becomes smaller.

Page 31 ZBL-R630A Rebar Detector 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.
Page 32 ZBL-R630A Rebar Detector 2) Quick check of whether thickness of cover meets the minimum designed value. Operation steps: 1) To set default diameter of tested rebar diameter. 2) To set the minimum cover thickness value for alarm. 3) While scanning the tested object, when thickness of cover is less than the set value, the buzzer alarms.
Page 33 ZBL-R630A Rebar Detector 4. Guide of quick operation 4.1 On-site preparation Before the start of test, grind or polish the tested object first. Uneven surface of objects will affect test results. Try best to keep the surface of objects even, it is conducive to sensor sliding on component surface. 4.2 To connect sensor to host To insert one end plug (in black) of signal wire to the left side corresponding socket of host, rotating clockwise and locking.
Page 34 ZBL-R630A Rebar Detector 4.7 Attention for field detection General principles of rebar test 1. Scanning surface should be relatively flat without higher protrusion. If surface is too rough and unable to remove, placing a thin plate on scanning surface and minus thickness of the thin plate in test result. 2.
