6. Make sure the ends of the truss rest on the span supports,
overlapping the supports at least 1/2 inch on both sides (Figure
19). If needed, use the thumbscrews on the back of the tester
to move the span supports where needed to support the truss
(Figure 20). Retighten the thumbscrews.
7. For triangular trusses, select the proper angle on the angle block
for the truss being tested (Figure 21). For flat trusses, unscrew the
angle block from the tester and replace it with the square block
(Figures 22-24).
