(4) Target Preparation for Scanning
Using chalk (or similar) make markings on the concrete surface to indicate where to start
testing (starting line) and where to scan (scan test line).
Make
sure the start line and the scan test line are orthogonal.
(As necessary, in order to perform a retest, use and endpoint of the wall as a standard
for the start line and scan test line)
A scan test applicable set up example is shown in Fig. 3-6.
