Position (6) temporary supports near panel seams exactly as shown in Figure 29.
Note: Temporary supports should be large enough to adequately support the reflector
and strong enough to easily support reflector weight without compressing.
Position theodolite, transit or laser level about 10 feet [3m] from outside perimeter of
reflector (see Figure 30).
Level theodolite/transit/laser level. If using theodolite, position view scope at 0.0 degrees
elevation, lock down elevation adjustment.
Site through theodolite/transit/laser level to determine where on measuring rod to place
steel rule onto rod to allow visibility of steel rule through theodolite/transit at all (6) six
measurement locations around reflector. Securely fasten both ends of steel rule to mea-
suring rod with adhesive tape (see Figure 30).
Temporary supports should be positioned as shown in Figure 31, close to but not inter-
fering with diameter setting bands.
Referring to Figure 31, 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.
Position measuring rod point down over temporary supports and on the flat portion of
the aperture face as shown in Figures 30 and 31, using theodolite/transit/laser level
carefully measure and record relative height of each of the (6) temporary support loca-
tions. Note: Measuring rod must be held in a vertical position during all measurements.
From the recorded data determine the relative height of each of the locations as com-
pared to the highest measured location. The differences between the highest location
and a lower location will be the amount of shim material required to place between the
reflector and the temporary support.
