Site through theodolite/transit to determine where on measuring rod to place steel rule
onto rod to allow visibility of steel rule through theodolite/transit/laser level at all (6) six
measurement locations around reflector. Securely fasten both ends of steel rule to mea-
suring rod with adhesive tape (see Figure 62).
Temporary supports should be positioned as shown in Figure 63, close to but not inter-
fering with diameter setting bands.
Referring to Figure 63, mark the measuring location at each of the six temporary sup-
port locations with a small dot (use felt tip marker) to be used as reference point in sub-
sequent measurements.
